How do salmon protect themselves?
To hide, salmon fry change their skin colour. They develop camouflage markings known as Parr marks, which are dark bars across their bodies. The mixture of light and dark helps them blend into the shadows on the stream- or lakebed so they are less visible to predators. They also dart very quickly from spot to spot.
Why do Salmon change colors?
Salmon change color to attract a spawning mate. Most of them stop eating when they return to freshwater and have no energy left for a return trip to the ocean after spawning. After they die, other animals eat them (but people don’t) or they decompose, adding nutrients to the stream.
How do salmon adapt to their environment?
Most Atlantic Salmon adaptations pertain to their habitat and means of feeding. The sleek design of a salmon allows it to quickly escape predators and also be an efficient predator itself. Atlantic Salmon have four sets of gills with specialized cells that allow them to migrate between salt and fresh water.
How does salmon get energy?
In the ocean, salmon travel in large, loose schools, and feed on small fish, krill, and crustaceans. Adult salmon head upstream, toward their spawning grounds—usually the same waters in which their lives began. Once salmon begin the trip, they will not stop to feed, deriving all their energy from stored fats.
