Dr. Anslem De Silva …… Herpetologist Renowned
A Facebook Note from Avishka Mario Seneviratne, April 2025
Buddhika Dassanayake and I were lucky to meet Sri Lanka’s foremost herpetologist (expert on amphibians and reptiles), the legendary Dr. Anslem de Silva, at his charming abode in Gampola. A skilled magician from Matara, de Silva has penned over 500 works since the ’60s.
Here he cradles “Floral Unicorn,” a Laki Senanayake piece, gifted to him by the late artist. For months, he’s generously guided me on my upcoming exploration of the mystical snake stones—said to draw venom from serpent bites.

He won two national awards at All Island Magic Competition and conducted massive shows from Matara to Jaffna. He also published 22 papers on magic. His son Panduka de Silva is also a naturalist where he worked in Andaman Islands on crocodiles.[2]
While at the school, he rescued a rat snake, which led him to move further in field of science. Then he started to rear few non-poisonous snakes, a baby saltwater crocodile, and a few sea turtles in his home, and villagers started calling him Hoony Mahaththaya (Mr Gecko) due to his frequent outings around the village to catch geckos as a food for snakes. At the age of 17, he read the book Snakes of Ceylon written by Frank Wall which induced him to start researching snakes throughout the country.[2]
In 1964, he joined Faculty of Medicine, Peradeniya, as the museum technician of the Department of Public Health. He retired from Department of Community Medicine in 2000.[4]
He is the founder and president of Amphibia and Reptile Research Organisation of Sri Lanka (ARROS), which he started in 1990.[4] ARROS is the first NGO in Sri Lanka aimed at reptile conservation. Due to his enormous contribution, de Silva was appointed as the chairman for Declining Amphibian Populations Task Force in the World Conservation Union (now the IUCN) for Sri Lanka. In 2015, he worked as the co-chairman of the Amphibian Specialist Group of the World Conservation Union.[4] He has published more than 450 research publications on herpetofauna in Sri Lanka for last fifty years. He was the first author to publish a reptile guide with coloured photographs. To create public awareness of reptiles and amphibians, de Silva published the Sri Lanka’s first series of posters illustrated with coloured photographs in 1990 and 2001.[2]
De Silva organised a number of events at fourth World Herpetology Congress and World Crocodile Congress. In 1991, University of Peradeniya conferred a Master of Science degree for his contributions to the field of zoology.[2] He also worked as a visiting lecturer at the Faculty of Veterinary Medicine and Animal Science, University of Peradeniya and Rajarata University of Sri Lanka.
