Average Size – Most sharks in this family are under 6ft with an average of 4ft
Kitefin Sharks have a slender body with a short, blunt snout, large eyes and thick lips and are brown or blackish in color. Often referred to as “Cigar Shaped.” They have very different teeth between the top and bottom jaws with the top being small and narrow and the lower larger and triangular in shape.
The most notable is likely the Cookiecutter Shark, known for their unique mouth and bite marks.
They live in tropical and temperate waters of the Northern Atlantic and in the Western and Central areas of the Mediterranean Sea. It can also be found in the Indian Ocean. They are most commonly found in depths of 200-600 meters(650-2400ft.) This family prefers outer continental shelves and upper continental slopes.
Bony Fish, Sharks, Rays, Cephalopods, Crustaceans, Polychaete Worms.
They have a large oil-filled liver allowing them to cruise through the water slowly and without using little energy.
They are strong predators with a powerful bite and large teeth and will sometimes take bites out of prey larger than itself. Cookiecutters have been known, on rare occasions, to take a nibble at a human, though they are not considered dangerous to us.
