THE AMPHIBIANS OF BHUTAN

This book: “The Amphibians of Bhutan” is all about the frogs, toads, salamander, and the obscure and enigmatic caecilians that occur in Bhutan. Of the more than 8,000 species of amphibians currently known worldwide, only 80 anurans, a single species of salamander (Caudata), and at least two undescribed caecilians (Gymnophiona) are recorded in Bhutan. This number is likely far less than accurate since there have been no serious attempts to document this group of animals by researchers or institutions, due to the fact that these moist-skinned animals, who use both land and water to complete their life cycle, do not attract funds for researchers and institutions to generate serious research. Species presented in this primer are thus through the interest of a few of us devoted, like-minded individuals who believe that these animals are extremely important to the life-support system for the Earth to survive.

This work is a result of the collection of information through an online group on the amphibians and reptiles of Bhutan created to educate the public about these neglected groups of animals. I wish to encourage more individuals to value and conserve these diverse and useful creatures. This book is not intended to replace formal batrachology courses nor is it designed for academic purposes. The goal of this book is to strengthen and facilitate connections between amphibians and the people who have a genuine or even a casual interest about the natural history of these interesting animals. And while this book touches on some academic aspects, it intentionally is more conceptual than statistical. For the average reader, common names have been provided while scientists and researchers must look at this work as something in between the core and the casual science. There are several new country records and a few undescribed and unknown species documented for the country (for further work), otherwise, nothing herein is ecologically or biologically new except for those few which are undescribed and unknown. I also freely admit that I have used all the information made available from all forms of media and from many individual citizen scientists and field foresters. In writing this manuscript, I have consulted numerous experts and sought their advice making the MS more than peer reviewed. But we humans all make mistakes – so, if you notice any, please do let me know. Being an amateur, it is even more susceptible to error. Therefore, I would like to suggest to my readers to view my primer less as a book and more as a resource that has its own style and character.

I did not initially think of writing a book; I thought of writing handouts that people can use and share to spread the word about amphibians being incredibly awesome. As such, you will see some vital facts repeated across the various topics, a combination of formal and casual fundamentals, and possibly other characters that might be considered mistakes in other settings.

I hope that book enthusiasts can take this work for what it is and not find its weaknesses too off-putting. This primer may benefit many interested English-speaking readers but I must confess that the examples and photographs are mostly those from Bhutan, not just to do justice to the title of the book but because I am one of those rare Bhutanese who takes batrachology very seriously. Consequently, the species in this primer are those that I am most familiar with, and as a result, not all the amphibian species occurring in Bhutan are covered. Hopefully, readers in other areas of the world can infer from the context which information may be applicable to their regions. Where an amphibian that is endemic to Bhutan appears as an example, there is likely a species which fills a similar ecological niche in your region, and a nominal amount of research should tell how the lesson might apply to your locality.

I wish to restrict the use of any of this information in any way unethical. So please contact me before doing so. I will almost certainly grant permission, provided you are using this material for educational purposes and public awareness and not for any political or commercial mileage. I have tried to be simple and straightforward, but this book does cover biological subject matter, and occasionally being exposed to unfamiliar scientific terms is a part of learning about the natural world. There is a glossary of herpetological terms available for you to refer to at the end of the book. I sincerely hope you enjoy my work!

Before concluding, I wish to make mention about our only endemic amphibian, the Bhutan Cat-eyed Toad, Scutiger bhutanensis. We have an obligation to investigate this species which was described at the turn of the century by scientists from Europe because we were not confident enough about its exact population or even its distribution. It is time that we take the future of these amphibians seriously and protect them using relevant research, funds and legislations. Otherwise, Bhutan might lose some species even before they have been described. It wasn’t too long ago that the endangered Gharial (Gavialis gangeticus) was extirpated from the Manas River in southern Bhutan. Let’s not allow history to repeat itself and let’s do our best to protect all animals, small or large that live in Bhutan. We must allow their survival so that our future generations may enjoy them as well. Happy reading!


Final Cover edited by the publisher Chimaira Books, Frankfurt aM, Germany. This primer talks about as many as 83 species found in Bhutan.

My late wife used to help me catch frogs although she did not like so much!
The cold mountains of the Kingdom are home to a number of flora and fauna including the batrachians.
A toad species from Chukha represents a unique Bhutan species.
Himalayan Toad is the most commonly encountered toad species in Bhutan.
The beautiful torrent frogs are part of the Bhutan Himalayan ecosystem that makes the Kingdom
special. 
The number of undescribed Minervarya species makes Bhutan a special place for further research.
Minervarya cf. orissaensis is my guess, but my colleagues think it otherwise.
This extremely healthy Nanorana is a signal that the Kingdom has a healthy population of amphibians.
A megophryd may be one of the most diverse sub groups in Bhutan.
Amolops species is another most diverse species in Bhutan.
The yet to confirmed Tylototriton cf. verrucosus is the only Salamander of the Kingdom which needs attention in case of local disease to the animals.
These caecilians from Tsirang and Dewathang are definitely undescribed and the Kingdom has a lot to do when it comes to this animal group.

A Guide to the Reptiles of Bhutan

Bhutan's First Reptile Book Available on Pre-Order

Our intention in writing this book is to trigger an interest in the subject - the science of reptile biology. “Herps”, as the group, along with amphibians, is popularly referred to, are thought to be sensitive to changes in the environment. Understanding their ecology and conservation problems can help us understand threats we face, such as climate change. These animals are also useful for agriculture and other industries, as they are predators of insect and rodent pests that damage the crops, and for disease control through their feeding on insects, snails, and others. 

Bhutan, a small kingdom in the eastern Himalayas is home to diverse flora and fauna. Conservation in Bhutan is currently focused on significant (here implying larger or economically useful) plant and animal species. Consequently, the tiger, snow leopard, elephant, and red panda, receive great attention, while snakes, lizards, tortoises, and turtles do not have conservation priority even if endemic or endangered. This book thus is an attempt to create awareness about this neglected group of animals. This book covers 82 species of snakes (out of ca. 102 species), 39 lizards and six turtles, a tortoise, and a crocodile. King cobras, Walnut kukri, Pythons, and almost all turtles and a tortoise are under the threatened category of the International Union for Conservation of Nature. Endemics of the country include the Bhutan Skink (Eutropis quadratilobus) and the Bhutan Agama (Calotes bhutanensis), both known only from the original descriptions. The species lost from the country’s fauna in the wild is the Gharial (Gavialus gangeticus). We have made an effort to limit the use of technical words, unless unavoidable. Common names and current scientific names have been mentioned. Range countries have been mentioned, and locations within Bhutan, if known, are specified.

Sizes

The sizes given are the maximum body length recorded for the particular species. For turtles and tortoises, it is the straight carapace length (CL) while for the lizards and snakes, the snout to vent length (SVL), and for crocodilians, total body length (TL).

On the cover is an Ampheisma snake which is yet to get a name. Concluded amateurishly as an A. parallelum, it could well be any species that are yet to be described. She is from Trashiyangtse Bumdeling and gave birth to three oblong white eggs in the first author's office at BWS headquarters.

We have beautiful lizards like Japalura variegata that occupy our beautiful forests. Sangay Tshewang like Foresters gets to see these animals in the wild so very frequently. By the way, the animal is from Dagana and its name is ........................ 

And then we have a critically endangered Yellow Tortoise, Indotestudo elongata from Pema Gatshel. Bhutan does have this species in various places like Sarpang, Gelephu, Samdrup Jongkhar, Zhemgang, etc. Gyembo Namgyal, an educated villager had to report its occurrence from Pema Gatshel.

We also have the King, Ophiophagus hannah that controls the herp food web in the wild. The image submitted by one Tashi, a Forester, comes from Jomotshangkha Wildlife Sanctuary in Samdrup Jongkhar District was feeding on a Trachischium species when Tashi took the photographs.
Not only that, but we also have some unnamed vipers. The suspected Trimeresurus medogenssis was first considered T. yunanensis by one Jigme Tshelthrim Wangyal, the only then Bhutanese Herpetologist. He later informed the scientific community that it could be a different species. Jigme Tshering in Trongsa thinks it is endemic to Bhutan which must be true!

The beautiful Russel's Viper is considered in India as one of the great four that causes fatalities in India. But in Bhutan, the species has never killed (no data at all but the possibility is not ruled out) a person to date. With just three sightings around the same places in the Sarpang district, I give the species a rare status in Bhutan. Sangay Dorji in Sarpang thinks that the species is rare in Bhutan.
Spectacled Cobra gets its name from the morphological appearance of the species on the back of its neck which bear two circular marks that appear like spectacles that people use. These are the animals that keep people safe and sound by eating animals that harm people. Ecosystem balancers!

The wonderful Himalayan Krait is a species of krait that does not come out much even in the breeding seasons. They carry venoms but they never bite human beings. Thus, the issue of the species being venomous is insignificant.
The innocent banded wolf snake lives in the temperate zone by elevations.

The Assam roofed turtle or Sylhet roofed turtle (Pangshura sylhetensis) is from Phuntsholing and is a critically endangered animal that Bhutan should be concerned about. But looks like it will not happen anytime soon since we have to focus on our stomachs more than animals. 

So, please order a copy. What are you waiting for?
