Where seen? This large sea cucumber with a spiky surface that resembles durian skin are sometimes seen on Pulau Semakau, on sandy areas near seagrasses. It appears to be more active at night. Elsewhere it is common on rubble and sandy areas; hidden under rocks or dead corals.

Features: About 20cm long, but can grow to 50cm long up to half a kilo in weight! Body hard, squarish in cross-section with a distinct upper and underside. The upperside has soft conical spine-shaped structures. The underside is flat with lots of short tube feet.
Yellowish or greenish grey. It is said that the sea cucumber disintegrates when it is removed from water or otherwise stressed.

Human uses: This is one of the sea cucumbers whose body fluids are harvested in Malaysia for 'Air Gamat', a local health tonic that believed to aid healing and other ailments. Choo describes how in some places, the fluids are drained from the sea cucumbers which are then returned to the net cages holding them. The fluids are boiled in oil together with some herbs.

According to SeaLife Base, it is probably not harvested for the sea cucumber trade because it disintegrates too rapidly to be processed for sale. According to the IUCN Red List: "Although it is not one of the most important species (low value) for fishery purposes, it can may become more popular after the depletionof other species of higher commercial importance and value."
