Nudibranchs & Flatworms of Lembeh

← Return to the main gallery · view other critters of Lembeh

This is a continuously updated documentation of all the Nudibranch & Flatworms species that live in the waters of Lembeh, made possible by our guest photographers and videographers. So far 101 species have been documented here, across 51 different genera. The newest addition is from August 2026.

How to navigate this page

Species are grouped by genus. Open Species documented to see every genus and the species recorded in each; choosing one jumps to its section and filters it.

Inside a section the pills filter to a single species. The number on each pill counts photographs and film moments together. Selecting a species hides anything that does not show it, so a species known only from film displays its film moments and no photograph rail.

Timestamps open the film on YouTube at that moment. Photograph captions link back to the gallery section the photograph came from, with its date and photographer.

Identifications & corrections

All the identification was done to the best of our personal knowledge. If you notice there’s an incorrect identification, then please let us know and we’ll update the documentation accordingly.
