Considered by many scientists the fastest fish in the ocean, [8] sailfish grow quickly, reaching 1.2–1.5 m (4–5 ft) in length in a single year, and feed on the surface or at middle depths on smaller pelagic forage fish and squid. Sailfish were previously estimated to reach maximum swimming speeds of 35 m/s (125 km/h), but research published ...
At the species level, length is significantly related to swimming ability. However, at the family level, only 16% of variation in swimming ability can be explained by length. [32] There is also a negative correlation between the fineness ratio (length of body to maximum width) and the swimming ability of reef fish larvae. This suggests a ...
Marlin are among the fastest fish, but speeds may be exaggerated in popular media, such as reports of 132 km/h (82 mph). [4] A 2016 study estimated maximum swimming speeds from muscle contraction times, which in turn limit the tail-beat frequency; the study suggested a theoretical upper limit for the black marlin's burst speed of 36 kilometres ...
Many sharks in the family are among the fastest-swimming fish, although the massive great white shark is slower due to its large size. Genera and species The family contains five living species in three genera and these selected extinct genera and species: [ 1 ]
The length of this fish is up to 3.15 m (10.3 ft) and the maximum published weight is 58.1 kg (128.1 lb). [ 4 ] In previous studies, sailfish hunting schools of sardines rely heavily upon stealth and quick slashing or tapping with the rostrum in order to temporarily immobilize prey and facilitate capture in small prey.
A great cormorant swimming. Aquatic locomotion or swimming is biologically propelled motion through a liquid medium. The simplest propulsive systems are composed of cilia and flagella. Swimming has evolved a number of times in a range of organisms including arthropods, fish, molluscs, amphibians, reptiles, birds, and mammals.
The larger species include the Atlantic blue marlin, Makaira nigricans, which can reach 5 m (16 ft) in length and 820 kg (1,810 lb) in weight [4] and the black marlin, Istiompax indica, which can reach in excess of 5 m (16 ft) in length and 670 kg (1,480 lb) in weight. They are popular sporting fish in tropical areas.
It grows to a length of about 9.5 cm [3] and is a carnivorous opportunist feeder. It feeds on small prey such as small crabs and other arthropods . [ 27 ] However, a recent molecular study suggests that P. argentilineatus is in fact a complex of species, with at least three separate lineages, one in East Africa, and two in the Indo-Malayan ...
