怎样认出它

Its spines regularly cover the whole aboral (back) side of its body.1
Its body plates are articulated, which makes the test (shell) quite flexible.1
It is most active at night.1

常被误认为： It was once considered a colour variant of Asthenosoma varium. In the Red Sea fire urchin, the spines cover the whole back side evenly. In A. varium, the spines are grouped in rectangular patches separated by bare areas.1

事实

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
