Vietnam’s Rhino Ratsnake Hatched in a European Zoo for the First Time


Keepers capture the moment a rhino ratsnake (Rhynchophis boulengeri) emerges from its shell at ZSL London Zoo — the first time this species of snake has been bred in a European Zoo.

ZSL London Zoo’s Reptile House produced a clutch of eight snakes, three of which have been exchanged with other European zoos in a program to increase the captive population of this species, which originates from the mountains of Vietnam.

The reptiles, which are often nicknamed “green unicorns” because of their hornlike features, will turn green when they reach around one year of age. They will reach about 40 inches (one meter) long and feed on geckos, frogs, and rodents.

Note: I will be adding photos from zoos to my blog from time to time. Zoos play a vital role in teaching urban people about animals and nature, which hopefully will encourage support for conservation of the same species in the wild. Increasingly, zoos are also serving as arks to shelter endangered species from the global extinction crisis.
