Ashok Captain, Herp Photography, & his Love for India

Ashok Captain is a world renowned herp photographer and Indian snake enthusiast. Read on to learn about some of favorite spots, hear some photography advice, and get a peek into his favorite herping trips.

How did you first become interested in reptiles/amphibians (particularly snakes) and photography?

A. Captain: In the 90's, we used to go on a lot of jungle trips - initially in the Western Ghats - places close to Pune (where I live). Most trips were during the monsoons (our rainy season) and we'd see a lotta creepies. Initially I tried to 'study' everything - monsoon plants, spiders, solifuges, amblypygids, scorpions, frogs, caecilians, lizards and snakes. I photographed all of these and needed captions for my slides (now digital images)! I soon gave up trying to 'id' everything and drifted towards snakes 'cos it was possible to do a lot (but not all) of the identification without killing 'em/ collecting 'em/ dissecting bits and pieces. This wasn't possible with several of the other animals.

Was anyone influential in your decision to go into herpetology as a profession?

Umm, nope. Snake taxonomy isn't a profession for me. Pros get funded to do this kinda thing. I spend most of my own money doing this stuff! Three guys who were extremely helpful (when I was a newbie) were Anil and Neelimkumar Khaire (brothers who run both the snake parks in Pune) and Rom Whitaker (he needs no introduction)! (Drum roll as Rom takes a bow).

Where is your favorite herping spot in the world?

Pretty much anywhere in India (I have a distinct Indian bias) though I have spent most of my 'field time' in the northern Western Ghats and eastern Arunachal Pradesh. 

Do you have any favorite herps to find in the wild? Anything that still gets you excited to find?

No favorite spots as such. Finding any herp is exciting for me!

Do you have a life list? If so, what herp is at the top of your list to find in the wild?

No life list as such, but I would love to see Indian Trimeresurus (Peltopelor) macrolepis; the Sri Lankan Trimeresurus (Craspedocephalus) trigonocephalus and the African Bitis gabonica (all in the wild).

Is there any country/area that is at the top of your list to visit still?

Injun bias again! In India, there are still so many places left to visit - the deserts, southern Western Ghats, Eastern Ghats, the Andamans, Nicobar Islands . . .


Do you keep any herps as personal pets? If so, what species and any favorites?

Nope. 'Tis illegal in India. We have a 'Wildlife Prevention Act' that does just that! Did not know that!

I know when I’m behind the camera I get pretty focused, have you had any “close calls”?

Nope, again. Yup, I get pretty focused too, but I usually have several folks I trust helping [me] with the snake and photography. If it's a hot 'un, there are usually two guys (with their mobiles switched off) with snake sticks between me (camera, tripod and flashes) and the model. Most of my pics are posed. There may be another 2-3 guys holding the flashes and/ or umbrellas. Sometimes its not possible to get a pic. That's okay.

What’s more exciting, winning a cycling competition, discovering a new herp species, or getting that perfect photo published on a cover?

All three are equally exciting! : )

What has been your favorite/most memorable herping trip you’ve ever made?

Actually 4 of 'em! 1. I once spent 8 months in Arunachal. It was to be a year, but I had to meet my landlord in Pune! Anyways, I saw 26 Trimeresurus (Viridovipera) medoensis and several other beautiful snakes in the wild. One of the Medo Pit Vipers made the cover of a Christmas supplement of Geo (Germany)! Impressive! 2. On another trip to Arunachal, with the help of the villagers, we found a Protobothrops kaulbackii. 3. In Maharashtra (the state I live in), some young herp enthusiasts found a snake they couldn't identify - I took a bus there and the snake turned out to be Elachistodon westermanni (previously thought to be extinct)! This was like finding a live dinosaur. 4. A professor who studies fish, found a snake in Trivandrum (it was netted by some fishermen). I went there and it was a Homalopsinae - Enhydris dussumierii. The only place in the world its found in is Kerala state, India. So its not always in the deep dark jungles (as seen on telly)!


Of the new species you’ve described and helped to describe, has there been a favorite?

Ahaetulla c.f. nasuta - Green Vine Snake           A. Captain/ R. Whitaker/ A.R.R.S.
I've not described any new species yet! New records for India, several - Sinonatrix percarinata; Trimeresurus medoensis; Lytorhynchus paradoxus, Protobothrops kaulbackii, Amphiesma venningii. . . . No favorites! I apologize for my mistake, as I had read some false information that stated otherwise.

For those of us that know nothing of Indian herp culture, is it a developing hobby to keep snakes as pets there?

In a bad (according to me) way. Though illegal in India, there are several 'sarp mitras' (snake friends) who keep snakes in the name of 'educating' folks. Let's be honest - its a man against dangerous 'beast' adrenalin rush. My opinion is that this is extremely uncool. We've so few wild spaces left in India that preserving our wild populations is way more important than having 'em in (usually) smelly bags/ boxes/ jars. This is very different [compared] to the herp culture elsewhere in the world.

A lot of people have a negative outlook of snake charmers in India, do you have an opinion you could share?

Chrysopelea ornata - Ornate Flying Snake
           A. Captain/ R. Whitaker/ A.R.R.S.
               (Agumbe Rainforest Research Station)
For me its kinda complicated. Sure, I'd rather see snakes in the wild, sure, but these guys are making a living 'using' snakes and have been for generations. Unless they get an equally profitable/ more lucrative means of getting cash, I doubt they're gonna quit (even if a few snakes are 'seized' by the authorities). In fact I think taking away their snakes is bad for the wild population. They'll go get some more (and deplete the wild population still further). Besides this, we misguidedly release the rescued snakes. This is daft 'cos we've no idea where the snakes originally came from; they'll most probably die in new territories/ ranges and if they're infected with mites or something worse, they could wipe out an entire wild population. 

I also see an amusing double standard - guys in the US catching snakes/ herps for profit are no different (from the snake's point of view) to Injun snake charmers. (Whoops, they got me! There goes my 'wild' life). Yet these folks are called snake wranglers! I'm not dissing 'em, nor am I pro-snake charmer (I am not). 

You’ve worked with several other herpetologists – anyone you’d like to work with again?

Yup lots of 'em actually! Rom (Whitaker), Kedar (Bhide), Varad (Giri), Aaron (Bauer), Mark (Wilkinson), David (Gower), Andreas (Gumprecht), Frank (Tillack), Patrick (David), Gernot (Vogel), others whom I've written to and would like to work with are Frederick (Wagner), Wolfgang (Wuster), Anita (Malhotra), Anslem (de Silva) and Van (Wallach).
  
Do you have any photography tips for shooting herps?

Be patient (be prepared to spend all day/ several days if necessary). Corny, but I think herps sense 'impatience' and one never gets a good picture if one is in this 'zone'. Use the best equipment one can afford. [It is] better to have a macro lens (as opposed to a zoom with a macro feature) than a 'fill up the memory card' fancy camera - 6 MP is fine. The lens is IMPORTANT. I use smart flashes off camera and a light tripod with an 'action head'. *Pelican cases (in plastic bags that are carried in rucksacs) also keep the camera gear alive in rain forests. I put a sock full of fresh silica gel into the case every time I open it (if I'm on a long trip). This keeps the inside relatively dry. *This sounds ridiculously unwieldy but read on . . . I wrap the cases in plastic bags 'cos we once crossed a river and, though the cases were watertight, I couldn't open them until water in the gutters had dried (this took ages in a rain forest). If you open them when wet, drops from the gutter actually enter the case and water is sealed into the case. I carry the cases in a rucsac, 'cos its impossible for me to carry a suitcase-type piece of luggage in rough terrain.

How did it feel to have a snake named after you in 2007 (Captain’s Wood Snake - Xylophis captaini)

Embarrassing actually, 'cos we didn't find it first. My mum dampened the mild euphoria (that came later) by saying something like - "It's dirty and brown like your room." Actually there are two snakes named after me (more embarassment). The other is Dendrelaphis ashokii.  

Here in the US, I hear a lot about how great the tropics are to herp – do you think India gets proper recognition for it’s herpetological diversity?

The tropics are different. Great to herp, I don't know. If one is out in the right season and at the right time, there is lots of 'stuff'. Off season (at least in our neck of the woods) everything disappears. Proper recognition? I don't know.

A school of herpetology at the North Orissa University has (or will be) opening this year in India, how do you think further herpetological education will influence the conservation of India’s herpetofauna? **Edit - I received some misinformation, corrected by Ashok. As it turns out, this school had been opened previously and was run more as a short course.

About 5 years back Dr Sushil Kumar Dutta got the Department of Science & Technology to part with some cash and arranged this 'school' once every year in different Universities/ institutions - the first was in northern Orissa (and the last from this grant), the others were at the Wildlife Institute of India (Dehra Dun), Guwahaty (Assam), and at SACON (Salim Ali Center for Ornithology and Natural History) close to Coimbatore. The 'school' lasts about 10-12 days and is pretty intense. Most of the 30 or so folks that attend are really sharp, and some of them have already started doing really good work, so it's helping. However, these efforts are all drops in the ocean till we sort out our problem of rapidly vanishing wild spaces. This issue is kinda political and ecological, and I'm gonna stick to taxonomy and not get stuck in conservation arguments.

Any herp publications in the works? A possible follow-up to 2004’s Snake of India, The Field Guide?

A few short notes. Rom wants 'at least 25 species additions' before we consider a follow up. Guess who has to go get 'em? Kidding. But yup, we'd definitely like to do another version. I'd like to add an annotated key as well, but Janaki (the editor) is of the firm opinion that no one will be able to lift the field guide if we keep adding stuff, so negotiations on point number two are still on.

Dr. William Lamar, Close Calls, & an Avian Life List

A look into how Dr. Lamar got his start in herpetology, what he's currently up to with research, and a very close call with one big, angry Bothrops atrox.

How did you first become interested in reptiles/amphibians?

Dr. Bill Lamar: I found a California Ribbon snake in my yard, it thrilled me and my mother was gently encouraging about it. Had she scolded me, likely I would be a Republican today. Also, from birth I was fascinated by dinosaurs.

Were your parents or friends influential in your decision to go into herpetology as a profession?

Only in the sense that no one ever discouraged me.

I’m in love with Central and South America myself, what draws you to those areas?

I was always drawn to tropical areas filled with mystery. As it happens, I landed a position with the Smithsonian Environmental Program that moved me to Colombia and I have concentrated on Latin America ever since.

Where is your favorite herping spot in the world?

Hmmm, I can't say I favor one over all others. I know of some places that have been extremely productive over the years, and they include spots in Costa Rica and Ecuador. In Ecuador I once collected 60 species of herps in one night.
Playa Ballena, Costa Rica

Do you have any favorite herps to find in the wild?

Not really. I have worked with all major groups and collected broadly. Certainly there are snakes that make me smile, such as boa constrictors, some ratsnakes, etc., and I am deeply interested in most kinds of New World venomous species of snake, so I like turning them up.

Do you have a life list? If so, what herp is at the top of your list to find in the wild?

I do not have a life list of herps, although I do of birds, interestingly enough. I suppose if I were to name a species it would be some nearly mythological species such as Corallus (Xenoboa) cropanii.

Is there any country/area that is at the top of your list to visit still? Why?

I would like to spend time in French Guiana because such large tracts of habitat are still intact. Unfortunately most parts of the world, no matter how remote, have become significantly compromised owing to human intrusion during my lifetime.

Do you keep any herps as personal pets? If so, what species and any favorites?

I do keep herps, although I do not consider them pets. Everything I keep is venomous and I do so to further familiarize myself with them.

Any crazy herping stories?

Oh, I could fill a couple of books with crazy stories. I did publish some viper encounters in an article in FAUNA Magazine. 
An excerpt from Dr. Lamar's article in FAUNA (2001) titled "Lucky Strike" - 
A couple of years ago, I hiked in a beautiful upland forest along the Rio Tahuayo, in Peru. It is filled with arching tress, and mosses and ferns so strange it seems like another planet. A clear, flat stream cuts the land like a flooded road. There is basically no rock in this part of the Amazon Basin, but the broad creek bed is aged clay that has the consistency of asphalt. At one point, it has collapsed creating a four-foot waterfall that crosses the stream like a jagged smile and forms a plunge pool below. On that day the water was chilly and running swiftly because it had rained all the previous evening. It was a classic "swimming hole," so I decided to jump in and cool off.
Eventually my companions began to arrive. They would be hot and sweaty and would waste no time in joining me for a dip. All were wading in the shallow stream in lieu of using the trail and one of them reached the pool ahead of the others. "There's a big snake swimming in the creek!" he shouted above the din of falling water. "What kind is it?" I yelled back. "I think it may be poisonous!" he replied. he kept glancing upstream behind him so I gathered that the snake was about to make its appearance. 
Standing with difficulty in the chest-deep, folling water, it was nearly impossible to ascertain anything about what was happening above. The laborious climb up from the pool was out-of-the-question. "Here it comes!" he said suddenly. I was bouncing up-and-down in an effort to see the streambed above, but the current kept knocking me back. "Just point your arm like a rifle at the snake to show me where it is swimming!" I instructed him. He did this, indicating - to my horror - a spot precisely in front of where I was standing.
I lunged sideways just as a large and thoroughly aroused B. atrox, floating high and striking at everything, came over the waterfall. Mouth half-open, she quickly turned her attention to me and I hit her point-blank in the face with a hard splash of water, pushing her back. In an instant, the current swept her past and she was thrown against the bank downstream where she (big ones are always females) made her way rapidly into the forest. Had I not been forewarned, the first thing that frightened snake would have contacted after plunging over the precipice would have been my head. Somehow, waterfalls will never be quite the same.

What has been your favorite/most memorable herping trip you’ve ever made?

Honestly, there have been so many I cannot single any one out.  Each has been special for different reasons: location, results, sights, some special species, etc. But I would have to say that the locals who have worked with me are what have really made those trips successful or at least memorable.

Of the new species you’ve described and helped to describe, which has been the favorite?

Hmm, again, there is no favorite. I have concentrated on each one and thoroughly enjoyed dealing with them. Currently, I am at work on a watersnake from the Amazon so that is where my attention lies, but I can honestly say I have enjoyed all of them.

You’ve worked with a bunch of other herpetologists – anyone you’d like to work with again?

Well, some of my favorites are no longer with us: my mentor Federico Medem, my friends Arthur Loveridge, James A. Peters, Charles Bogert, among many others. Among extant herpetologists, I enjoy the company of Jonathan Campbell, Roy McDiarmid, Bob Reynolds, Norm Scott, Jay Savage, Bill Duellman, and young guys such as Dante Fenolio.
  
Being into photography and herps, what do you find more satisfying finding a species in the wild you haven’t seen before or having a photo published on the cover of a book or magazine?

They are very different things but finding something new is always exciting, although it usually will be a small, drab brown thing...nothing spectacular.

Any advice for people that want to get more involved in field herping, but don’t have the educational herpetology background?

Well, formal education is not really all that conducive to learning herpetology. I, like most herpetologists, am basically self-taught. Live with books, ask lots of questions, THINK about things, observe, observe, observe.

Who do I go to if I need a Costa Rican herp identified, you or [Costa Rican herpetologist] Alejandro Solorzano?

Craugastor bransfordii, Costa Rica - identified
 by Jay Savage through e-mail.

Either one of us could likely help, as could Mahmood Sasa, Quetzal Dwyer, Jay Savage, and others.


Diasporus diastema complex, Costa Rica - identified
 by Jay Savage through e-mail.
Do you think the increase of interest in the herp-keeping hobby has helped or hindered reptile & amphibian conservation?

I wish I could put a pretty face on conservation, and I certainly believe in it, but the sheer mass of humanity and the damage they do is so overwhelming I have to admit that I mostly feel it to be something of a fait accompli that all this stuff is going away. Certainly, during my 37 years spent in the Orinoco and Amazon Basins as well as Central America and Mexico, the steady disappearance of species has, if anything, accelerated.

Are you currently carrying out any herp research at UT Tyler you could let us all in on?

Right now all I am involved with are descriptions of a new lizard and a new snake. I am also working on an amphibian conservation program in Chile. It involves captive reproduction as well as field studies.

Anything else you’d like to share?

As I look back on my life I am deeply grateful for all the wonderful times spent in primitive situations far from human settlements.  I feel as though I have come as close to living my life as though I had been born 100 years prior, that I am satisfied with this. For me, the natural world is everything, so I cherish the opportunities I have had to enjoy it.

Dr. Marc Hayes, Integral Bd Research, & Herp Photography

Ever wonder how herpetologists got started in their professions or the current research their performing? Read on to get some insight into the life of Dr. Marc Hayes, the Oregon spotted frog, and how photography can play a part in furthering herp research.
Jade Tree Frog (Rhacophorus dulitensis) - Sabah, Borneo

How did you first become interested in reptiles/amphibians?

Dr. Marc Hayes: Walking ephemeral streams checking for breeding Anopheles mosquitoes on algal mats as an entomologist for the Goleta Valley and Carpinteria Mosquito Abatement Districts in Santa Barbara County, California.

Were your parents or friends influential in your decision to go into herpetology as a profession?

No, but they always encouraged me to follow my interests in the biological arena. I began actually in Marine Biology and got a Bachelors degree in Marine Biology with [an] Entomology Minor, which led to my first job with the Mosquito Abatement District. My reason for trying Marine Biology was the influence of my mother's mother, who is French, I am first generation American; my mother was a war bride. In any case, my grandmother has a rather strong personality and she wrote Jacques Cousteau several times indicating I wanted to be a Marine Biologist; of course, that was her idea, not mine. In any case, I tried Marine Biology for awhile, and liked it, but it was just not my passion as much as it was my grandmother's. I was fairly interested in Entomology for awhile, but the herps really caught me.

What led your interests towards amphibian conservation specifically?

Seeing the loss of habitat for amphibians in California in the 1970s and rapid development eliminating or degrading habitat.

However, among herps, I was originally interested in snake conservation, but it was difficult to cuItivate an interest in snake conservation in the 1970s, and I saw the early handwriting on the wall with amphibian problems and began working on ranid frogs that I knew would become at risk species; that panned out faster than I ever imagined.

Where is your favorite herping spot in the world?

The Great Basin of Oregon

Is there any herp that still gives you chills and sends your excitement levels through the roof when you spot it?

California Kingsnake

We all have animals we would love to find in nature, what herp is at the top of your list to find in the wild?

Bushmaster
Bushmaster (Lachesis stenophyrs) - Costa Rica


Is there any country/area that is at the top of your list to visit still? Why?

Borneo-Sarawak - because there is still much unexplored area there herpwise.
Brown Bullfrog (Kaloula baleata) - Sabah, Borneo


Aside from specimens for study, do you keep any herps as personal pets? If so, what species and any favorites?

Not any more, I prefer to see them in the wild. Historically, I kept as many as 25 different snakes, but it takes a lot of care if you are going to do it right, which I have always viewed as a must. Now, I take great pleasure in doing macrophotography of herps.

Could you share any crazy herping stories?

Got bit by a green palm viper in Costa Rica back in 1983. I was measuring a juvenile that I hand pinned on the table. Its head slipped out from under the pin because I was trying to hold it down too delicately. I did not pull my hand away fast enough and it struck me on the tip of the index finger. When I pulled away, I pulled the fang out of its mouth and ended staring at the fang for a few seconds. The tip of the fang [had] hit a blood vessel and I could see the blood move up through the venom canal in the translucent fang (it was a very small snake – roughly 200 mm snout-to-vent). Anyway, that made be realize it was a dry bite, but I nevertheless sucked on it for awhile and watched it carefully over the next few hours; fortunately, nothing happened.

Your known for your work with Washington State’s declining amphibian populations, what has been your greatest achievement (to date) towards amphibian conservation?

Finishing a 150+ page literature review on tailed frogs (genus Ascaphus), which is in the review process as we speak.

If you weren’t a herpetologist, what would you be doing professionally?

I would be a hydrologist because stream systems fascinate me.

What is the number one conservation threat to Washinton’s endangered amphibians – over-collection, pollution, global warming, Bd, invasives? Why?

Habitat loss and degradation related to human activities of diverse kinds, because humans are a historically and still growing impact that will not be reversed until the human population size shows a reversing trend.

In a 2010 study you carried out on the Oregon Spotted Frog (Rana pretiosa), you found that your exposed specimens recovered from the Batrachochytrium dendrobatidis (Bd) fungus. Do you believe the species may hold a key to preventing Bd in other amphibian populations?

Not clear, some species are resistant, others are not, that situation is largely genetically based. Oregon spotted frog resistance appears to be related to have some unique skin peptides, one of which is not shared with any other frog species (at least known to date). How that might contribute to making other species resistant is unclear with modification of the genome of the susceptible frogs to include the coding for the resistant peptide. Technology has the potential to do this, but there are complications to actually effecting it in frogs.

What would a cure to Bd mean in the herpetological world?

Wonderful for the susceptible species. A lot of the spread of Bd, however, is via the pet trade and Bd prophys [prophylactics] are available, so this is a great way to cut down on spread if you can get pet trade folks interested enough to do it. It would also cut down on captive animal losses considerably saving dealers considerable $$.

What’s the best avenue people can help your conservation efforts (donation links, volunteering, becoming part of the Pacific Rivers Council, etc)?

I do not think there is any absolute best way, and folks can contribute in ways that their means allow them to. However, education is very high up there among better ways. People cannot be interested in what they do not know about; and there are a lot of folks out there that are ignorant of the biological riches of this earth.

I have a few friends currently doing amphibian and Bd research abroad in Australia and Guyana for PhDs, any advice for them? Or students looking to get into the herpetological research profession?

Choose a project you can be passionate about and that will never feel like a drudge, co-operate with folks willing to share equally, and do as much as you can without burning yourself out (you only live so long).

Do you think the increase of interest in recent years in the herp-keeping hobby has helped or hindered reptile & amphibian conservation?

I think it has helped enormously. Many, if not most herp hobbyists have a really [strong] interest in taking the best care of their charges, which has greatly improved the quality of care for many hard to keep species. Further, quality captive breeding reduces the need to collect in the wild. Academics and others can learn a lot from the pet hobbyists and vice versa, they just have to be tolerant of their respective directions.

If I need a US amphibian species identified, whom do I turn to?

There is a Professional Herpetologist blog linked to Facebook that trades ID info all over, it is global, not just US.

Anything else you’d like to share about you or your research?

You must come up with these questions in your sleep. I recently got into wildlife camera work that either takes video footage or stills at almost any frequency of resolution one would want. We tried it first by putting cameras on the first Oregon spotted frog egg mass lay-site we have been monitoring for several years (here, you have to understand that the species lays communally). One day out, at a frame [capture rate of] every 30 seconds resolution we got gorgeous shots of two ovipositional sequences, and I got completely sucked into it. Herp folks using this will revolutionize natural history knowledge of diverse herp species
