FAMILY CETORHINIDAE

BASKING SHARKS

A large robust shark with 5 very long gill slits that almost meet at the top and bottom of the head, all before the pectoral fins; gill rakers long and hair like; many very small teeth with a single point; two dorsal fins, the first much larger and situated between the pectorals and pelvics; tail fin nearly symmetrical, concave; tail base very depressed, with a large keel on each side.

This family contains a single, circumglobal species, which is primarily temperate but enters the northern and southern fringes of our region.
