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 ...
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 ...
The latter group swim slowly, but can turn rapidly, as is needed when living in coral reefs for example. But they can not swim as fast as fish using their bodies and caudal fins. [1] [2] Skeletal anatomy of Tilapia [3] Consider the tilapia shown in the diagram. Like most fish, the tilapia has a streamlined body shape reducing water resistance ...
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 is a fast-swimming fish with a prominent lateral keel and four to six finlets after the anal and second dorsal fins. [3] Escolar can grow to over 2 metres (7 ft) in length. Like its relative the oilfish ( Ruvettus pretiosus ), escolar cannot metabolize the wax esters (gempylotoxin) naturally found in its diet.
The guinea pig (or cavy) is noted as having an excellent swimming ability. [38] Mice can swim quite well. They do panic when placed in water, but many lab mice are used in the Morris water maze, a test to measure learning. When mice swim, they use their tails like flagella and kick with their legs. Many snakes are excellent swimmers as well.
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 ]
Mudskippers can grow up to 30 cm (12 in) long, and most are a brownish green colour that ranges anywhere from dark to light. During mating seasons, the males will also develop brightly coloured spots in order to attract females, which can be red, green or blue. Unlike other fish, the mudskipper's eyes protrude from the top of its flat head.
