Definition of blacktip shark
: a small, grayish requiem shark (Carcharhinus limbatus) with black-tipped fins that is widely distributed in coastal tropical and subtropical seas The vast majority of shark bites are from so-called hit-and-run attacks by smaller species, such as blacktip sharks. They mistake thrashing arms or dangling feet as a prey item, dart in, bite and let go when they realize it's not a fish. — Tim Friend
