With the exception of two sea urchin samples collected from Puerto Rico, most chromium residues reported in echinoderms have been less than l.Omg/kg DW. The elevated levels of 24.0 and 43.0mg/kg FW of whole organism in Puerto Rican sea urchins are exceptions, which were not reflected in sea cucumber muscle from the same vicinity, and thus should be viewed with caution. Echinoderms from the United Kingdom and environments were comparatively low in chromium concentrations were less than 0.46 mg Cr/kg DW whole organism. Embryos of a sea urchin (Anthocidaris sp.) developed normally in solutions containing 3.2. 2 mg Cr/L, but failed to develop at 8.4-10.0 mg Cr/L. Larvae of another species of sea urchin (Hemicentrotus sp.) were more sensitive, showing abnormal development or dying within 24 h at concenttations of < 1.0 mg Cr/L. Hexavalent chromium at 6.0 mg/L was associated with abnormal development in embryos of Anthocidaris crassispina. 

The shell of the sea urchin, Anthocidaris crassispina, contains a mixture of two sulphoglycolipids whose structures were confirmed by chemical and physicochemical methods.The lipids were l -0-palmitoyl-3-0-(a-D-quinovo-pyranosyl-6-sulphate)glycerol (96%) and its myristoyl counterpart (4%).
