Common name: Urchin Boring Genus

Echinostrephus is a genus of sea urchins known for their unique ability to bore into rock, creating habitats that can be used by other marine organisms. These urchins are characterized by their small size and distinctive, flattened spines. They are fascinating additions to reef aquariums, where they contribute to the bioerosion process and help maintain a natural balance. Hobbyists should provide them with ample rockwork to mimic their natural environment.
