Atlantic Blue Marlin - Makaira nigricans
The Atlantic blue marlin (Makaira nigricans) is a species of marlin endemic to the Atlantic Ocean. The Atlantic blue marlin (hereafter, marlin) feeds on a wide variety of organisms near the surface. By using its bill, it can stun, injure, or kill while knifing through a school of prey and then return later at its leisure to eat. Marlin is a popular game fish and has commercial value because its meat has a relatively high fat content. Marlin are distributed throughout the Atlantic's tropical and temperate waters; they are more populous in the western parts. It is a blue water fish that spends the majority of its life in the open sea, far away from land. The biggest females are more than four times as heavy as the biggest males. Males rarely exceed 160 kilograms (350 lb) in weight, and females commonly weigh over 540 kilograms (1,200 lb). The longest females can reach a length of more than 4 metres (13 ft) with the bill, from eye to tip, constituting about 20% of the total body length. Both sexes have twenty-four vertebrae, of which eleven are precaudal and thirteen are caudal. The bill is long and stout. Both the jaws and the palatines (the roof of the mouth) are covered with small, file-like teeth.
Swordfish - Xiphias gladius Swordfish, also known as broadbill in some countries, are large, highly migratory, predatory fish characterized by a long, flat bill. They are a popular sport fish of the billfish category, though elusive. Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific and Indian oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft). They commonly reach 3 m (9.8 ft) in length, and the maximum reported is 4.55 m (14.9 ft) in length and 650 kg (1,400 lb) in weight.
