Toxopneustid Sea Urchins [Toxopneustidae]

Description

Toxopneustidae sea urchins are often found on reefs and rocky bottoms, where they graze and shelter among crevices. Divers may notice their spines and sometimes a more compact, “button-like” look compared to other urchin families. They’re typically calm to observe—just keep distance, as their spines can be sharp.
