Oncorhynchus rastrosus (originally described as Smilodonichthys rastrosus [2]) also known as the saber-toothed salmon (now known to be a misnomer), [3] or spike-toothed salmon [1] is an extinct species of salmon that lived along the Pacific coast of North America and Japan. [4]
This is a list of North American animals extinct in the Holocene that covers extinctions from the Holocene epoch, a geologic epoch that began about 11,650 years before present (about 9700 BCE) [A] and continues to the present day. [1] Recently extinct animals in the West Indies and Hawaii are in their own respective lists.
Oncorhynchus is a genus of ray-finned fish in the subfamily Salmoninae of the family Salmonidae, native to coldwater tributaries of the North Pacific basin. The genus contains twelve extant species, namely six species of Pacific salmon and six species of Pacific trout, all of which are migratory (either anadromous or potamodromous) mid-level predatory fish that display natal homing and ...
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 65 extinct fish species, 87 possibly extinct fish species, and six extinct in the wild fish species. [ 1 ] [ 2 ] Cartilaginous fish
The taimen appears to be the largest salmonid in the world, being heavier at average and maximum sizes than the largest North American salmonid, the chinook salmon. [ 3 ] [ 4 ] [ 5 ] Most mature fish caught weigh from 15 to 30 kg (33 to 66 lb). [ 6 ]
Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of July 2017, the International Union for Conservation of Nature (IUCN) listed 1,000 critically endangered fish species, including 87 which are tagged as possibly extinct. [1] [2] Of all evaluated fish species, 3.0% are listed as critically endangered ...
The IUCN also lists ten fish subspecies as endangered. Of the subpopulations of fishes evaluated by the IUCN, 24 species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction".
