Black-Fringed Sea Cucumber (Holothuria Leucospilota)

This front view of the frequently encountered Black-Fringed Sea Cucumber (Holothuria Leucospilota) clearly shows the "papullae" protruding from the skin.
These are one of the most obvious characteristics that distinguish this species from the closely related Black Sea Cucumber (Holothuria Atra).

Variegated Sea Cucumber (Stichopus Variegatus)

This photograph of a Variegated Sea Cucumber (Stichopus Variegatus) was taken at Sail Rock, at a depth of around 25m.
The light was pretty poor so the photograph isn't the best, but it shows quite clearly the characteristics of this species.

Magnum Sea Cucumber (Neothyonidium Magnum)

If i am correct in my assumption that this is a Magnum Sea Cucumber (Neothyonidium Magnum), then this photograph would indicate that they are present in differing colour variations.

Warty Sea Cucumber (Cercodemas Anceps), Black Sea Cucumber (Holothuria Atra), Medusa Worms (Synaptula Lamperti)

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.

Godeffroy's Sea Cucumber (Euapta Godeffroyi)

The Godeffroy's Sea Cucumber (Euapta Godeffroyi) is one of a number of related species of Sea Cucumber that are often found clinging to Barrel Sponges (Xestospongia Testudinaria).
These large sponges are often covered in a layer of algae, which is one of the main food sources of the Godeffroy's Sea Cucumber.

Marbled Sea Cucumber (Pearsonothuria Graffei)

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.
