English: Manitou darter, zebrafish; French: Dard-perche, fouille-roche.
Maximum total length 7 in (18 cm). Long, fusiform fishes with conical nose and banding on the sides of the body that becomes more irregular posteriorly. Body color is greenish brown.
North America from Hudson Bay east to the Atlantic coast, west to Saskatchewan, and south through the Great Lakes region to the Gulf of Mexico.
Spread through many habitats, but primarily gravel- or sandybottomed, medium-sized rivers. Also bottom dweller in weedy lakes, usually some distance from the shoreline.
Perhaps their most notable
occurs during feeding, when they frequently use their noses to root prey out of the substrate and from beneath stones.
FEEDING ECOLOGY AND DIET
Feeds on zooplankton, particularly copepods.
Moves into shallow waters or rivers to spawn in the spring. The male becomes more vividly colored and develops tubercles on its ventral side. A gravid female approaches a school of males, which follows her to the substrate. Following the release of eggs and milt, the female and often the males engage in rapid wriggling, which serves to churn up the bottom and bury the eggs. No parental care for eggs or young.
Not listed by the IUCN.
