All sharks in the Endothermic teleosts (bony fishes) are all in the suborder Scombroidei and include the billfishes, tunas, and one species of "primitive" mackerel (Gasterochisma melampus). Some species of fish maintain elevated body temperatures to varying degrees. However, hyper-saline lakes like the Great Salt Lake do not support fishes. // Fish ecology Fish can be found in almost all large bodies of water in salt, brackish or fresh water, at depths from just below the surface to several thousand meters.
Endothermy, though metabolically costly, is thought to provide advantages such as increased contractile force of muscles, higher rates of central nervous system processing, and higher rates of central nervous system processing, and higher rates of central nervous system processing, and higher rates of central nervous system processing, and higher rates of central nervous system processing, and higher rates of digestion. See also gigantothermy. The degree of endothermy varies from the billfish, which warm only their eyes and brain, to bluefin tuna and porbeagle sharks who maintain body temperatures elevated in excess of 20 °C above ambient water temperatures. All sharks in the family Lamnidae – shortfin mako, long fin mako, white, porbeagle, and salmon shark – are known to have the capacity for endothermy, and evidence suggests the trait exists in family Alopiidae (thresher sharks). Endothermic teleosts (bony fishes) are all in the suborder Scombroidei and include the billfishes, tunas, and one species of "primitive" mackerel (Gasterochisma melampus).
