Eurynome aspera

Lore & Background

Eurynome aspera has a bipartite rostrum forming a double point, with the two points widely separated, each broad at the base and tapering forwards. The postorbital spine is laterally expanded, and the antorbital spine is absent. Many areas of the carapace have tubercles. The second and third peduncular segments of the antenna are broad, and the eyestalks retract. The chelipeds are equal in size, but those of the female are shorter and less developed than in the male. The body and legs are pale red to brown, occasionally blue-grey, and the tubercles (warts) are white or brown. This species has been confused with Eurynome spinosa, as noted by Hartnoll, 1961.

Reader's Guide

Eurynome aspera is significant as a species within the family Majidae, distinguished by its small size and cryptic coloration. Its carapace and legs are often encrusted with algae and mud, providing effective camouflage in its habitat. The species has been historically confused with Eurynome spinosa, a taxonomic uncertainty preserved in the literature. Its depth range extends from the lower shore to 180 metres, and it is found in the East Atlantic, Mediterranean Sea, and South Africa. The description of its rostrum, spines, and tubercles aids in identification, and the sexual dimorphism in cheliped development is noted. References include works by Ingle (1997), de Kluijver & Ingalsuo, and Hartnoll (1961), which clarify its distinction from related species.
