Lissocarcinus orbicularis, common names sea cucumber crab[2], red-spotted white crab,[1] and harlequin crab[3] is a species of crab in the family Portunidae,[1] gaining one of its names from its close-knit relationship with holothuroids, the sea cucumbers.[3]
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.[4]
Diet
L. orbicularis has an obligatory relationship with sea cucumbers of the genera Thelenota, Bohadschia and Holothuria, feeding on the surface tissue of these tropical echinoderms. Although their primary source of nutrition, this species is also known to feed on a diverse array of food including sea grasses, and they also absorb and digest organic matter.[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.
