Great hammerhead

Description

The streamlined body of the great hammerhead with the expanded cephalofoil is typical of the hammerhead sharks.Adult great hammerheads can be distinguished from the scalloped hammerhead and the smooth hammerhead by the shape of the cephalofoil,which has a nearly straight front margin (as opposed to arched),with prominent medial and lateral indentations.The width of the cephalofoil is 23–27% of the body length.The teeth are triangular and strongly serrated,becoming more oblique towards the corners of the mouth.There are 17 tooth rows on either side of the upper jaw with 2–3 teeth at the symphysis (the midline of the jaw),and 16–17 teeth on either side of the lower jaw and 1–3 at the symphysis
