Muscle of the Atlantic salmon, Salmo salar. Muscle comprises a large part of this fishes body. Its arrangement on the skeleton permits very flexible fish movements. Blocks of muscle (myotomes), as seen here, contain fibres running longitudinally down the body. Their contraction gives the salmon the whiplash action of its tail. Such muscle is well supplied with blood and fat which gives it its colour and rich flavour. With this muscle equipment the salmon is able to migrate long distances across the sea. And it has the arduous task of having to swim powerfully upstream rivers to spawn.
