Eziokwu
It often shelters commensal shrimps, including Allopontonia iaini and Periclimenes colemani, and the parasitic gastropod Leutzenia asthenosomae.1
Until 1998 it was considered a colour variant of Asthenosoma varium.1
Sea urchins are close relatives of starfish, crinoids, brittle stars and sea cucumbers. Together these are called echinoderms, meaning 'spiny skins'.1
