Paracentrotus is a genus of sea urchins commonly known as the Purple Sea Urchin. They are notable for their robust, spiny appearance and are found in various marine environments, often in rocky areas.

Hobbyists should be cautious as their spines can be sharp and potentially harmful to more delicate tank inhabitants.
