How far a salmon travels in the ocean and the direction it goes can vary. Many salmon travel along with the ocean currents in circular routes. Some wander as far as 2,000 miles from their stream. Others stay closer to home. The salmon grow to adults on rich seafood diets including small fish like herring and anchovies.
Salmonids can become food for larger fish and animals like tuna, seals, dolphins and whales.
But even in the ocean a salmon has ways to help it escape these predators. They feed mostly at night when they are harder to see. Their color also helps to hide them. Seen from above they look dark like the deep ocean. But since the water looks white or silvery from below, they have silver, shimmering bellies.
