The oceanic
whitetip shark is a stocky and heavy set animal, up
to 4 meters (13 feet) in length, with an enlarged first
dorsal fin and large paddle like pectoral fins. The
tips of the dorsal fins, caudal lobes and pectoral fins
are mottled white on adults while juveniles may also
have black marks. However the amount of pigmentation
on the fin tips varies and is occasionally completely
absent. The rest of the body is dark gray or olive gray
in colour. The upper teeth are broad and triangular
with serrated edges while the lower teeth have narrow
serrated cusps and broad bases.
