The main predators of Arctic char include sea otters ("Enhyrda lutris"), polar bears ("Ursus maritimus"), humans ("Homo sapiens"), ferox trout (Salmo ferox), and other fish species. Dwarf Arctic chars are also often cannibalistically consumed by giant Arctic chars. As ferox trout are an apex predator, Arctic char is thus a key species throughout many lakes in its range.
