The Atlantic blue marlin (hereafter, blue marlin) feeds on a wide variety of organisms near the surface. It uses its bill to stun, injure, or kill while knifing through a school of fish or other prey, then returns to eat the injured or stunned fish. Marlin is a popular game fish. The relatively high fat content of its meat makes it commercially ...
Marlina Hirasaka & H. Nakamura, 1947. Orthocraeros J. L. B. Smith, 1956. Makaira (Latin via Greek: μαχαίρα "sword") is a genus of marlin in the family Istiophoridae. It includes the Atlantic blue and Indo-Pacific blue marlins. [2] In the past, the black marlin was also included in this genus, but today it is placed in its own genus ...
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 Peterson Field Guides (PFG) are a popular and influential series of American field guides intended to assist the layman in identification of birds, plants, insects and other natural phenomena. The series was created and edited by renowned ornithologist Roger Tory Peterson (1908–1996). His inaugural volume was the classic 1934 book A Field ...
Classification. The marlins are Istiophoriform fish, most closely related to the swordfish (which itself is the sole member of the family Xiphiidae). The carangiformes are believed to be the second-closest clade to marlins. Although previously thought to be closely related to Scombridae, genetic analysis only shows a slight relationship.
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 ...
Ascension Island is an isolated 88-square-kilometre (34 sq mi) large volcanic island in the Atlantic Ocean. [1] It rises from the sea floor as part of the Mid-Atlantic Ridge. [2] The protected area covers the entirety of the island's territorial waters and exclusive economic zone. [1] [3] : 2 In total, 443,571 square kilometres (171,264 sq mi ...
The Peterson Identification System is a practical method for the field identification of animals, plants and other natural phenomena. It was devised by ornithologist Roger Tory Peterson in 1934 for the first of his series of Field Guide s [1] (See Peterson Field Guides.) Peterson devised his system "so that live birds could be identified ...
