About Carpilius convexus (Forskål, 1775)
Carpilius convexus, commonly known as the marbled stone crab, is a species of crab that occurs in the Indo-Pacific region, ranging from Hawaii to the Red Sea and South Africa. It was first described by Peter Forsskål in 1775 under the name "Cancer convexus", and has sometimes been classified as a variety of the larger species Carpilius maculatus. Overall, the biology of the entire genus Carpilius is poorly understood. The body of Carpilius convexus is yellow-brown or red, with mainly brown patches, and individuals can grow up to 25 cm (9.8 in) across. Beyond its size, coloration, and general distribution and habitat, very little additional information is known about the biology of this species.
