Distribution and ecology

Lissocarcinus orbicularis grows to about 4 cm (1.6 in), and has a smooth, glabrous carapace with distinctive spots. The carapace is slightly shorter than it is broad and has a highly convex shape.

This species has a commensalistic relationship with certain sea cucumbers. It can be found within the gut cavity, or near the oral tentacles and anus of sea cucumber species Holothuria whitmaei, Actinopyga obesa, and most commonly Holothuria atra.[3]

Distribution

The type locality for this species is Fiji, and it is widely distributed in the Indo-Pacific. It is also found in the Red Sea.
