Missouri Fish Identification

A dichotomous key is a tool used to ID trees, wildflowers, mammals, reptiles, rocks, and fish. "Dichotomous" means "divided into two parts.” Therefore, dichotomous keys always give two choices in each step.

Start With Family

Begin at beginning.Need to use glossary for

definitions. One bad guess and you lose.Ex. Pectoral and pelvic fins

absent, Lampreys Go to page 38.

On To Genus

Need to use pictures of anatomy. One bad guess and you lose.Ex. Eyes developed; Dorsal fin divided

into two distinct parts - go to page step 6.
