why do fish have skeletons and muscles
Fish muscles come in three different types, red, pink and white. Most fish have a mixture of two, or all three, types of muscle, but keep the types in discrete groupings, however in the salmonid fishes the red and white muscle types are mixed to form a mosaic type of muscle.almon are a particularly good fish for studying the basic shape of fish muscle because the coloration of their muscles allows you to see the edges of each myotome, as in the picture above and the photos below. The myomeres are not flat sheets of muscle, but are folded into a 3-d shape.
