The diagram below is one example of many illustrations found in the "Illustration Gallery" and it shows where certain anatomical structures occur on baby fish shown in this Web site. Each species is unique with its anatomy. In the "Illustration Gallery" the fins and other anatomical features on the illustrations are not labeled, so it is necessary to learn how to identify these features. Notice that there are usually three views of the same baby fish, a dorsal (back), lateral (side) and ventral (belly) view. This arrangement allows observers to view the baby fish in a 3–dimensional perspective. If you have questions and/or uncertainty when viewing a particular species, refer back here for clarification. The melanophores were emphasized and drawn as close to their actual appearance and position as possible.

Whole specimens were drawn almost symbolically because greatest attention and time was to be put upon individual and groups of melanophores on their bodies (Ref. 22). Myomeres, which are prominent on preserved specimens, were consciously omitted because they interfere visually with certain patterns of pigmentation on the bodies. Fin rays were usually drawn symbolically with a solid line along one side of a ray and either an incomplete, dashed line or (sometimes) nothing at all along the other side. A dashed line is the symbolic representation for the tissue (precursors of hypural bones) that is thickening and becoming opaque in the caudal fin area. The symbolic representation of yolk materials is a dashed line showing different quantities but not different kinds of yolk. The symbolic representation of eyes involved shading highlights in black optic cups and lighter lenses.
