註釋
Mako sharks, shortfin mako and longfin mako, belong to the family Lamnidae, which also includes the great white shark. Makos have very ancient origins, appearing in prehistoric oceans between 40 and 60 million years ago. The elegant shape, the curved prominent teeth and the tail shaped like a halfmoon make them unmistakable. The shortfin mako can be considered among the fastest of all sharks, since it can reach speeds of 35-56 km/h and can jump out of the water to more than 6 meters in height. Makos have the speed and agility to catch fast swimming prey, such as tunas, swordfishes and dolphins. Some makos have been found with a swordfish bill driven into their body after fighting with prey. Makos are considered dangerous animals: attacks on divers, swimmers and boats are known, but are rare because these predators prefer offshore waters. The shortfin mako is fished all over the world and is prized for the high quality of its meat. Moreover its fighting temper makes it one of the most sought-after prey by the sport-fishermen.
