The Spatangidae are a family of heart urchins. There are four recognised genera within the family; Maretia, Paramaretia, Pseudomaretia and Spatangus.[1] Additionally, Spatagus and Prospatangus were previously recognised genera within the Spatangidae, but are now accepted as part of the genus Spatangus.[1]
The Spatangidae are marine heart urchins that feed on subsurface deposits and graze.[1]
