External structure diagram

A diagram of general fish morphology.

These are generalised diagrams on the shape and internal structure of fish. There are great number of differences between species. These differences can relate to body shape, relative size of each fin, Number of rays, colour, shape and function, as well as internal structure and positioning of the organs.

These diagrams are based on the typical shape and internal structure of bony fishes.
