Fish are aquatic vertebrates that are typically cold-blooded; covered with scales, and equipped with two sets of paired fins and several unpaired fins. Fish are abundant in the sea and in freshwaters, with species being known from mountain streams (e.g., char and gudgeon) as well as in the deepest depths of the ocean (e.g., gulpers and anglerfish). They are of tremendous importance as food for people around the world, being either collected from the wild (see fishing) or being farmed in much the same way as cattle or chickens (see aquaculture). Fish are also exploited for recreation, through angling and fishkeeping, and fish are commonly exhibited in public aquaria. Through the ages, many cultures have featured fish in their legends and myths, from the "great fish" that swallowed Jonah the Prophet through to the ever-popular half-human, half-fish mermaid.

Deep sea fish is a term for fish that live below the photic zone of the ocean. Examples include the lanternfish, flashlight fish, cookiecutter shark, bristlemouths, anglerfish, and viperfish
The fish of the deep sea are among the most strange and elusive creatures on Earth. Since many of these fish live in regions where there is no natural illumination, they cannot rely solely on their eyesight for locating prey and mates and avoiding predators; deep sea fish have evolved appropriately to the extreme sub-photic region in which they live.
Many deep sea fish are bioluminescent, with extremely large eyes adapted to the dark. Some have long feelers to help them locate prey or attract mates in the pitch black of the deep ocean. The deep sea angler fish in particular has a long fishing-rod-like adaptation protruding from its face, on the end of which is a bioluminescent piece of skin that wriggles like a worm to lure its prey. The lifecycle of deep sea fish can be exclusively deep water although some species are born in shallower water and sink on becoming adults.
Selected fish of the month
The weather loaches or weatherfishes of the genus Misgurnus is a genus of loaches in Asia and Europe. They receive their common name from the ability to detect changes in barometric pressure and react with frantic swimming or standing on end. This is because before a storm the barometric pressure changes, and this is known to make these fish more active.
The dojo loach, or Misgurnus anguillicaudatus, an Asian weather loach species, is a common aquarium and food fish. Like many other loaches, they are slender and eel-like. They can vary in color from yellow to olive green, to a common light brown or gray with lighter undersides. The mouth of the loach is surrounded by three sets of barbels. It uses them to sift through silt or pebbles to find food. It also uses them to dig under gravel and sand to conceal itself out of nervousness or defense unlike the other loaches who use the spines beneath the eyes.

The spotted gar (Lepisosteus oculatus) is a primitive freshwater fish of the family Lepisosteidae, native to North America from the Lake Erie and southern Lake Michigan drainages south through the Mississippi River basin to Gulf Slope drainages, from lower Apalachicola River in Florida to Nueces River in Texas, USA. The fish is a voracious predator feeding on various kinds of fishes and crustaceans. They are notable for being one of the few extant fish species with ganoid scales
