Two-lined Caecilian

Rhinatrema shiv


The two-lined caecilian lives in just 777km²!

This species is very rare but is likely to be widespread across Kaieteur National Park. The main threat to the species is gold and diamond mining, which affects the habitat this species lives.

Improved management of the national park where the two-lined caecilian lives is required along with further research into the distribution, population status, life history and ecology.
