Mammals Of Alaska
This is a list of all mammals currently found in the U.S. state of Alaska, whether resident or as animal migration, migrants. With 112 mammal species, Alaska ranks 12th of the 50 U.S. states in mammalian diversity. Not included in this list is the Steller's sea cow, an extinct sirenian that was once native to Alaska's Aleutian Islands before being hunted to extinction in 1768.Domning, D. 2016.

This article presents the common and scientific names for each species, along more information about the animal. Where the species is unique to Alaska, this article presents a brief overview of the species. Where the species is not unique to Alaska, this article gives information about the habits and distribution that are characteristic of animals occurring in the state.

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...
