Stichopus horrens

Stichopus horrens is a variable, grey to green/black sea cucumber from the Indo-Pacific. It is often variegated with dark patches. It is a medium-sized species (to 30 cm) with a smooth tegument but large and irregular papillae. The big tubercles and irregular body form give an "irregular, soft and almost repulsive" appearance. Spicules are tables and large "C" bodies (S. horrens spicules). S. horrens many be found on reefs, below rocks on flats.
