Tag: Marbled Sea Cucumber (Pearsonothuria Graffei)

The Marbled Sea Cucumber (Pearsonothuria Graffei), also known as the Blotched or Black and White Sea Cucumber, is a reasonably common species around the shallow, inshore reef areas (particularly around Koh Tao), although it is not found in the large numbers of some of its relatives.

Although often classified as Bohadschia Graffei, this species was apparently re-classified as Pearsonothuria Graffei in 1984 due to differences with other Bohadschia species.

As one of the more active species of Sea Cucumber in local waters (in relative terms of Sea Cucumber "activeness"!!), it is also one of the easiest to identify with its overall pale/mottled brown colouration. The prominent brown/black "retractile feeding tentacles" at the front of the body are white on the underside.

This photo of a Marbled Sea Cucumber (Pearsonothuria graffei), taken at Tanote Bay (Koh Tao), shows a less common colour variation of its "retractile tentacles". In local waters they tend more often to be black and white.
