Common name: Pincushion Urchins
Scientific name: Chaetasteridae
The family Chaetodontidae, commonly known as Pincushion Urchins, includes a variety of sea urchins found in tropical and subtropical oceans. These echinoderms are characterized by their round, spiny bodies which play a significant role in their defense mechanism. They are detritivores, feeding on algae and decomposing organic material, which makes them beneficial for controlling algae growth in reef aquariums. Hobbyists appreciate them for their unique appearance and their utility in maintaining a clean tank environment.
