Blue marlin are distributed throughout the tropical and subtropical waters of the Atlantic Ocean. A bluewater fish that spends the majority of its life in the open sea far from land, [2] the blue marlin preys on a wide variety of marine organisms, mostly near the surface, often using its bill to stun or injure its prey. Females can grow up to ...
One family, Xiphiidae, contains only one species, the swordfish Xiphias gladius, and the other family, Istiophoridae, contains 11 species in four genera, including marlin, spearfish, and sailfish. [13] [14] Controversy exists about whether the Indo-Pacific blue marlin, Makaira mazara, is the same species as the Atlantic blue marlin, M. nigricans.
The classification of the Indo-Pacific blue marlin (M. mazara) and the Atlantic blue marlin (M. nigricans) as separate species is under debate. [1] Genetic data suggest, although the two groups are isolated from each other, that they are both the same species, with the only genetic exchange occurring when Indo-Pacific blue marlin migrate to and ...
Makaira nigricans Lacepède, 1802 (Atlantic blue marlin); Makaira mazara (Jordan & Snyder, 1901) (Indo-Pacific blue marlin); Although they are traditionally listed as separate species, recent research indicates that the Atlantic blue marlin (Makaira nigricans) and Indo-Pacific blue marlin (Makaira mazara) may be parapatric populations of the same species.
A taxidermied marlin greets visitors to Dare County, North Carolina. In the Nobel Prize -winning author Ernest Hemingway's 1952 novel The Old Man and the Sea , the central character of the work is an aged Cuban fisherman who, after 84 days without success on the water, heads out to sea to break his run of bad luck.
The title of the largest member of this order, the most numerous order of all vertebrates, is a matter of some debate. A large marlin is the biggest of these fishes: the black marlin (Makaira indica) of the Indo-Pacific, the Atlantic blue marlin (Makaira nigricans) and the Indo-Pacific blue marlin (Makaira mazara). All of these similarly sized ...
There is a dispute based on the taxonomy of the sailfish, and either one or two species have been recognized. [3] [4] No differences have been found in mtDNA, morphometrics or meristics between the two supposed species and most authorities now only recognize a single species, Istiophorus platypterus, found in warmer oceans around the world.
The heart is a muscular organ found in most animals.This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]
