Raja cortezensis (lat.) Is a species of cartilaginous fish of the rhombus family of rays of the order of stingrays. They live in subtropical waters of the east-central part of the Pacific Ocean between 28 Β° C. w. and 25 Β° c. w. They are found at a depth of up to 80 m. Their large, flattened pectoral fins form a rhombic disk with a slightly elongated snout. The maximum recorded length is 38.5 cm. Eggs are laid. They are not the target fishing target [1] [2] [3] .

The species was first scientifically described in 1988 [4] .
These demersal ramps live off the coast of Mexico in the Gulf of California . They are found on the continental shelf to a depth of 80 m [2] [3] .
The broad and flat pectoral fins of these slopes form a rhombus disk with an elongated snout and rounded edges. On the ventral side of the disc are 5 gill slits, nostrils and mouth. On the long tail there are lateral folds [1] . The maximum recorded length is 38.5 cm [3] .
Like other rhombic, these stingrays lay eggs enclosed in a rigid horn capsule with protrusions at the ends. Embryos feed exclusively on yolk [3] . Males reach puberty at a length of 34 cm [2] .
These skates are not subject to targeted fishing. May be caught as by- catch when trawling shrimp. The data for the assessment of the conservation status of the species by the International Union for Conservation of Nature are insufficient [2] .
