Black Spine-necked Swamp Turtle

Acanthochelys spixii

The dark turtle with a groove along its shell and a neck bristling with soft spines. Much harder to see than the side-necked turtle.

The groove that names it in Spanish (canaleta) runs along the shell from front to back. The neck, folded sideways like its lagoon cousin, is covered in small soft spines. It lives in shallow, heavily vegetated marshes, hunting invertebrates and amphibians.

Behaviour

Aquatic and discreet: it spends its life among the vegetation of shallow water and rarely exposes itself on open logs.

How and when to see it

Spring and summer, in shallow marshes. Seeing one is a small prize: log it if it shows up basking on the bank.
