Definition for View source for Trapezia rufopunctata

''Trapezia rufopunctata'' is a species of guard crabs in the family Trapeziidae. ''T. rufopunctata'' can reach the size of about 5 cm. It has quite long, flattened clawed legs (chelipeds). The squarish carapace has a spectacular mottled drawing, with about 100 to 200 reddish or orange spots on a white or pink background. This guard crab, like other members of the family, lives symbiotically in association with corals (usually hard corals of the genus Stylophora and Pocillopora), hiding deep within the coral branches. It feeds on coral tissue and mucus, and defends the corals from predators, like the coral-eating starfish ''Acanthaster planci''.
