Field Guide

In Missouri, the harlequin darter occurs only in our southeastern lowlands, in flowing streams and ditches with sandy bottoms. It is State Endangered because its small numbers and limited range make it vulnerable to extirpation.

Unlike most other darters, the swamp darter prefers swamps and sloughs with no current at all. Rare in our state, it’s found only in a few southeast Missouri locations.

The central mudminnow is is the only mudminnow that occurs in our state, and it is rare, occurring only in a few marshy locations near the Mississippi River. Mudminnows are closely related to the pikes.

The golden shiner is a deep-bodied minnow with a greenish-olive back and a faint dusky stripe along the midline. It has a fleshy keel along the midline of the belly. It is widespread in Missouri.

The fathead minnow has a blunt, rounded snout, rounded fins, a dusky stripe along the side, and a spot at the base of the tail fin. It is most abundant in pools of small prairie creeks because it tolerates rather high temperatures, extreme turbidity, and low oxygen.

The cypress minnow, like its Bootheel swampland habitat, is in danger of vanishing from Missouri. On the forward part of this fish's side, note the distinct cross-hatched pattern made by the dark-edged scales.

The brook silverside is a little fish that is very active in the daytime and on bright, moonlit nights.

One of the rarest Missouri minnows, the taillight shiner is known only from a few localities in southeast Missouri, in habitats representing the last remnants of low-gradient streams and swamps once common in that region.
