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 ...
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.
Sailfish were previously estimated to reach maximum swimming speeds of 35 m/s (125 km/h), but research published in 2015 and 2016 indicate sailfish do not exceed speeds between 10–15 m/s (35–55 km/h). During predator–prey interactions, sailfish reached burst speeds of 7 m/s (25 km/h) and did not surpass 10 m/s (35 km/h).
[13] [14] Controversy exists about whether the Indo-Pacific blue marlin, Makaira mazara, is the same species as the Atlantic blue marlin, M. nigricans. FishBase follows Nakamura (1985) [ 13 ] in recognizing M. mazara as a distinct species, "chiefly because of differences in the pattern of the lateral line system".
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 ...
The average catch for 2013-2017 was 113,000Mt with swordfish and Indo-Pacific sailfish accounting for around two thirds of total catches followed by black marlin, blue marlin and striped marlin. [10] In the last few years, 75% of all billfish catches were recorded by five countries comprising Indonesia, Iran, India, Sri Lanka and Taiwan, China ...
Compared to similarly sized fish, mammals and birds typically have brain sizes fifteen times larger, though some species of fish such as elephantnose fish have very large brain-to-body ratios. However, fish still display intelligence that cannot be explained through Pavlovian and operant conditioning, such as reversal learning, novel obstacle ...
The World Wildlife Fund and the Zoological Society of London jointly issued their "Living Blue Planet Report" on 16 September 2015 which states that there was a dramatic fall of 74% in world-wide stocks of the important scombridae fish such as mackerel, tuna and bonitos between 1970 and 2010, and the global overall "population sizes of mammals ...
