Definitions of terms are given in brief as many can be found online in far more detail, but searches can turn up numerous definitions unrelated to fish, so this Dictionary helps narrow that search down and concentrates terms in one place. The illustrations complement the text and are not found in similar, shorter glossaries and in dictionaries based on, or borrowed from, this one. Browsing the Dictionary may prove educational for students of fishes.

Examples of less technical terms:- cornobbled = hit with a fish scaled = both having scales and lacking scales
