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 ...

Black marlins spend more time closer to the surface than most other billfish, except for sailfish. [17] Scientists found in one population of black marlin that at night the fish would spend up to 87% of their time at depths above 30 meters deep, but during the day less than 60% of their time was spent in the upper 30 meter depths of the sea.

The swimming ability of a reef fish larva helps it to settle at a suitable reef and for locating its home as it is often isolated from its home reef in search of food. Hence the swimming speed of reef fish larvae are quite high (≈12 cm/s - 100 cm/s) compared to other larvae.
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.
Mudskippers are any of the 23 extant species of amphibious fish from the subfamily Oxudercinae of the goby family Oxudercidae. [2] They are known for their unusual body shapes, preferences for semiaquatic habitats, limited terrestrial locomotion and jumping , and the ability to survive prolonged periods of time both in and out of water.
A water-quality problem will affect fish behaviour and can be shown by clamped fins, reduced feeding, erratic swimming, and gasping at the surface. [55] Seahorses require vertical swimming space to perform reproductive functions and to prevent depth-related health conditions like gas bubble disease, so a refugium that is at least 20 inches by ...
The kick is sometimes cited as the fastest way to swim. [2] [3] [4] An article published by Slate described it as the "fastest way for a human to swim" when executed properly. [4] An article in the International Journal of Performance Analysis in Sport noted that the kick provides "an incontestable advantage from a hydrodynamic point of view".
