Cruriraja

Cruriraja is the only rajid genus of the Crurirajidae family of the stingrays. These are cartilaginous fish leading the bottom lifestyle, with large, flattened pectoral fins in the shape of a rhombus and a protruding snout. On the ventral side of the disc are 5 gill slits, nostrils and mouth. The tail is long and thin.

These stingrays live in the western Atlantic Ocean , off the southern coast of Africa in the Indian Ocean from shallow water to depths over 1000 m. They reproduce by laying eggs enclosed in a strong horn capsule with protrusions at the corners ^{[1] [2] [3]} .

The name of the family comes from the words lat. crus - “limb” and lat. raja - "stingray".
