Rajidae (Skates)
Etymology: Caliraja: The prefix name Cali- refers to the state of California, United States and Gulf of California, Baja California, Mexico, the regions where the types of all four recognized species were described.
Eponymy: The etymologies do not help, but we believe these species are named after the Sea of Cortez where the holotypes were caught, or in the case of the eelpout, Cortez Bank off San Diego, California. (Ref. 128868), visit book page.
