Stichopus Sea Cucumbers; Synallactida

The Stichopus Sea Cucumbers are squat, square-profiled, thick-bodied creatures. You can see many of them when scuba diving on the reefs at our local dive sites.
They are not easy to identify – amongst these underwater photos we might have a new species from Koh Phangan!!

Commonly known as the spiky or black knobby sea cucumber - for obvious reasons.

An ugly, warty, pustulose beastie - seen on 2 occasions.

A chunky beast - usually found around coral reefs, filter feeding away...

Some we are sure of, for others we are waiting for confirmation of identity...
