Horn sharks are found in the eastern Pacific ocean, from central California to Central America.
Females average about three feet, while males range from three to four feet.
They have five gill slits, two dorsal fins with anterior spines, an anal fin, crushing teeth. These sharks average about 3-4 feet in length. They are named after the spines on their dorsal fins which resemble horns. They are gray or brown with small spots scattered on their fins and body. They are aggressive only when stepped on, and inflict only a superficial wound.
