Echinocardium Explained

Echinocardium is a genus of sea urchins of the family Loveniidae, known as heart urchins. The name is derived from the Greek ἐχῖνος (echinos, "hedgehog, urchin") and καρδία (kardia, "heart").^[1]

Taxonomy

The genus was first described in 1825 by John Edward Gray,^{[2] [3]} and the type species is Spatangus pusillus Leske, 1778 by subsequent designation.^[4]

In 1836, the genus Amphidetus was described by Louis Agassiz,^[5] and is now considered a synonym of Echinocardium.^{[6] [7]}
