Tag: Black Sea Cucumber (Holothuria Atra)

The Black Sea Cucumber (Holothuria Atra) is by far the most common species of Sea Cucumber (Holothuroidea) found in local waters.

Growing to a maximum length of around 60cm, this species is easily identified by its overall black/dark brown colouration, sometimes with lighter spots. Its "retractable feeding tentacles" are the same colour as the body.

Although a Benthic species, Black Sea Cucumbers are usually found in close proximity to coral reefs, and are often found with their body partially hidden under overhanging rocks or coral heads.

This Warty Sea Cucumber (Cercodemas Anceps) was photographed under Chaloklum Pier, Koh Phangan (one of the best places to find one) and was obviously feeding at the time as its colourful "retractable feeding tentacles" are fully extended.
