Wart Slugs are easily spotted on our Koh Lanta diving trips and are instantly recognisable by the warty mantle and lack of dorsal gills.
Most species look similar and are black and white, with a possible third colour usually being yellow or orange. A limited few species may also have some pale green or pale blue colouring. In some species, the warts may be connected by ridges.
The mantle skirt covers the foot, and unlike other nudibranchs, the gills are located along the underside and side of the body.
There are two tentacles on the dorsal surface of the head canned rhinophores, and these tentacles are used to detect water movement and scents in the water, and can be retracted if necessary. Wart Slugs have no jaws or teeth, instead sucking on their food, mainly sponges.
Wart slugs are hermaphroditic, meaning that individuals have both male and female reproductive organs.
