we saw a mangrove slug.

There are more than 15 species in several genera of shell-less mangrove slugs all over Singapore mangroves, burrowing in the mud, on the forest floor, under wood and even climbing trees!Species identification is difficult, requiring an examination of the texture and features on the dorsal and ventral surface, and even the arrangement of internal organs! Hence they are often referred to collectively as 'Onchs' - which means lump! (Onchidium is the Latinised derivation of the Greek word for 'little lump'!).
