Life Underground!
Linnaeus caecilian is well adapted to a life underground with their eyes covered by skin to protect them and having little purpose.
They spend their time seeking out insects such as earthworms on which they can feed.
This species is poorly studied and little is known of their breeding behavior and life history.
They occur in a number of protected areas and it is unlikely their numbers have suffered any significant declines.
Read on to learn more about these amazing amphibians.
Appearance
What does the Linnaeus Caecilian look like?
The upper side of their body is covered by bluish-gray skin with paler coloration on the underside. Across their body the skin is very smooth.
