Cruriraja is a genus of small rays comprising eight speciesthat occurs in the tropical Atlantic and Indian Oceans .
features
Cruriraja species are 30 to 60 cm long and have a diamond-shaped body disc with more or less straight front edges and rounded rear edges. The pelvic fins are deeply split, the front section is leg-like and consists of three segments each, the rear lobe can be fused with the tail root. Like the rays of the Anacanthobatidae family , the Cruriraja species are referred to as leg skates in German because of this leg-like part of the pelvic fins and accordingly in English as "leg skates". Cruriraja species have two dorsal fins located on the upper end of the tail. The claspers are small and spade-shaped. Cruriraja species are oviparous (laying eggs).
