Borenan Dark-necked Slug Snake (Asthenodipsas borneensis)

https://youtu.be/071uogTZ1Ro

Range: The island of Borneo.

Habitat: Mature forest.

Place in the ecosystem: The Bornean Dark-necked Slug Snake and its close relative the Malayan Slug Snake are unique among slug snakes in that they appears to feed exclusively on slugs and not snails. This could be why unlike other slug snake species they shows no asymmetry in its jaw and tooth structure.

The Bornean Dark-necked Slug Snake was once considered the same species as the Malayan Slug Snake (Asthenodipsas malaccana) despite quite clear visible differences. A January 2020 paper by Quah et al. described them as distinct species for the first time.
