Additional informationShortfin makos, otherwise known as bonito sharks, are powerful and active sharks, known for leaping out of the water when in pursuit of prey or when hooked. The shortfin mako has a rapid growth in comparison to other pelagic sharks, and grows almost twice as fast as the porbeagle (Lamna nasus). It is also more slender than the porbeagle and lacks a second caudal keel (Compagno, 1984).
