Description

Echinocardium cordatum is a sea urchin that may reach 9 cm in length. The thin test is globular, slightly oval and its upper face is flattened. It is densely covered by yellowish short thin spines. As it lives buried in sand or mud, this type of spines creates a ventilated space between sand and its tegument preventing asphyxiation. It can bury 10 cm deep in sand where it feeds on various micro-organisms.

Distribution

Echinocardium cordatum is found from 5 m to 200 m deep, in the Atlantic Ocean from Norway to South-Africa, in the English channel, the North Sea and the Mediterranean Sea.
