Atlantic salmon return from the ocean to fresh water to reproduce, nearly always to the same river where they were hatched. As spawning time nears, the male's head changes shape to develop a pronounced hook on the lower jaw. While Pacific salmon die after reproducing, Atlantic salmon can spawn more than once.

Larval salmon stay in fresh water for the first 2-3 years of life before moving offshore. They are able to withstand cold temperatures in fresh or salt water. Adult salmon are eaten by seals, sharks, whales and humans.
