59. Cantor’s Giant Softshell

Pelochelys cantorii


Cantor’s giant softshell is an exceptionally large freshwater turtle, with individuals known to reach over 1 metre in length and weigh more than 100 kilograms! Sadly, these extraordinary turtles are on the brink of extinction.

This strange-looking turtle is also referred to as the ‘frog-faced softshell’ due to its odd facial features. These turtles have an extremely large distribution, from Bangladesh to the Philippines and Borneo, and it is possible that it actually comprises more than a single species. Cantor’s softshell is a freshwater turtle but, unusually for most freshwater species, is also found in brackish coastal waters.

There are three extant softshell species of the genus Pelochelys, and these three species diverged from all other turtles over 40 million years ago. This is more than 10 million years before the divergence separating humans and baboons! The family to which these amazing turtles belong diverged from all other living creatures more than 140 million years ago, when dinosaurs still roamed the Earth.

Cantor’s giant softshell is under threat from harvesting by local people for meat, accidental killing and persecution from fishermen when caught in fishing gear, and the destruction of its freshwater and coastal habitats. The species is listed as Endangered by the IUCN Red List however, at the time of writing, this assessment is long out-of-date and in urgent need of updating.

Cantor’s giant softshell is listed under Schedule I of the Indian Wildlife Protection Act, designated as a First Grade Protected Animal in China, and is also a protected species in Myanmar and in Vietnam. The species is listed on CITES Appendix II. Despite the dire situation facing this species, the establishment of Asian turtle conservation initiatives provide hope for the survival of this and many other threatened species.
