“Black Sea Cucumber” (Holothuria leucospilota)

…a species of Holothuriid sea cucumber which occurs in shallow waters around the east coast of Africa and the western Indo-Pacific region, including Australia. Black sea cucumbers typically inhabit areas with “cover” like corals and seaweed clumps, and is notably tolerant of changes of salinity/temperature. Like other sea cucumbers H. leucospilota is a scavenger feeding on a range of detritus and other nutrients it can find in the benthos.
