    Species of salmon can spend from 1 up to 6 years in the ocean as they mature and grow into adults. While in the ocean growing, salmon feed on small fish, squid, eels, and shrimp. When salmon are ready to reproduce, they migrate from the ocean back into freshwater rivers and streams to their spawning grounds.

During this time, the male salmon develop hooked jaws and humpbacks, while the female salmon develop a swollen belly and reddish coloration.
