[42] [43] Teleost diversity becomes low at extremely high latitudes; at Franz Josef Land, up to 82°N, ice cover and water temperatures below 0 °C (32 °F) for a large part of the year limit the number of species; 75 percent of the species found there are endemic to the Arctic.

The Arctic lamprey is a commercially important edible fish with fatty flesh. It is reared in aquaculture. [4] The ammocoetes are used as bait. Threats to the spawning habitat of this species include pollution and the regulation of water flow by damming. Nevertheless, the IUCN has assessed this species as being of "Least Concern". [1]

They are demersal fish living on or near sand, gravel or clay bottoms at depths of between 50 and 2,000 m (200 and 6,600 ft). The halibut is among the largest teleost (bony) fish in the world, and is a threatened species owing to a slow rate of growth and overfishing. [3] [4] Halibut are strong swimmers and are able to migrate long distances ...

Water is an important part of human survival. Because of its cold temperature, much of the Earth's water comes from the polar regions. 90% of the world's water comes from the Antarctic ice cap although a lot of this water is not used. [11] Water environments are important for many species around the world.
About two percent of fish species can change their sex during their lifetimes. Some tropical fishes like many in the wrasse family (Labridae) actually change sex based on their age and size.
Alaska blackfish are small, with an average length of 108 mm (4.3 in), but have been known to reach 330 mm (13 in). [3]They have an easily distinguishable morphology (a branch of biology dealing with the study of the form and structure of organisms and their specific structural features), with relatively large, posterior dorsal fin and anal fins, large, lobed pectoral fins located just ...
