Info
Echinoecus sculptus lives exclusively in association with the helmet sea urchin (Colobocentrotus (Podophora) atratus).
Some publications refer to a symbiotic relationship between the two species, i.e., a community of two different species that live together for mutual benefit.
Other reports indicate that Echinoecus sculptus lives as a commensal with the sea urchin, i.e., a relationship in which one species benefits while the other neither benefits nor suffers harm.
In the original description, carapace data from several crabs were documented. The largest female had a carapace length of 5.75 mm and a width of 6.45 mm, while the largest male measured 5.3 mm in length and 5.75 mm in width.
Nothing else is known about the biology of the sea urchin crab.
The crab Echinoecus sculptus (Pilumnidae) (A) was named in 1935 by the Australian carcinologist Melbourne Ward and is so far only known from Christmas Island near Australia.
