Centrostephanus nitidus

Centrostephanus nitidus is a sea urchin in the family Diadematidae. It is a marine echinoderm with the characteristic hard test and spines associated with sea urchins.

The species is associated with a smooth or glossy appearance, reflected in the name nitidus. That feature helps distinguish the item from sea urchins described mainly by spine length or coloration.

It is primarily associated with deep marine environments and the seafloor. Records place the species in the Indian Ocean region, although species-level distribution should be checked against a current taxonomic database.

Yes, it belongs to Diadematidae, the family that includes many long-spined sea urchins. Its family placement connects it with the genus Centrostephanus and other deep-water echinoids.
