Pacific Salmon have a remarkable migration pattern. After spending several years in the ocean, they return to the exact river or stream where they were born to spawn. This can involve traveling hundreds or even thousands of miles from the open ocean to the freshwater spawning grounds.
During the spawning season, male Pacific Salmon develop a hump on their back and a hooked jaw, also known as a kype. They use these features to fight other males and attract females. Female Pacific Salmon dig nests called redds in the gravel beds of rivers where they lay their eggs. Male Pacific Salmon then fertilize the eggs by releasing sperm over them.
