Blue-black urchin
The blue-black urchin is a spiny sea animal that lives on tropical coral reefs. It is black or blue-black, with long spines that show a blue shine in the light. It grazes on algae during the night and hides in cracks and under rocks by day.1

Yeroo baay'ee kan itti wal fakkeessan: Echinothrix calamaris has banded spines, except in juveniles, and dark forms show a greenish tinge rather than blue. Diadema setosum has longer spines, a smaller test (the body shell) and an orange ring around its anal sac.1

The shrimp Stegopontonia commensalis lives on it, and the shrimp Saron marmoratus stays close to it for protection.1
Fish of the families Apogonidae (cardinalfish) and Centriscidae (razorfish and relatives) also stay close to it for protection.1
Its grazing contributes to bioerosion, the slow wearing down of reef structures.1
It is active at night and hides in crevices, burrows and under rocks during the day.1
