Family

Common name: Sea Urchins

Scientific name: Parechinidae

The family Parechinidae encompasses a group of sea urchins found in various marine environments. Members of this family are characterized by their globular shape and spines that can vary in length and sharpness. They play a crucial role in the ecosystem by grazing on algae, which helps prevent overgrowth and maintain the balance of reef systems. In the aquarium, they can serve as a natural form of algae control. However, care should be taken to ensure that they are compatible with other tank inhabitants and that their spines do not harm more delicate species.
