The central mudminnow tends to spawn in mid-April in temperatures of 13 degrees Celsius with the higher temperature stimulating the spawning.

The eastern mudminnow (U. pygmaea) can be found across the eastern United States and south eastern Canada.

The Olympic mudminnow is the only species in genus Novumbra, and one of seven species worldwide in the family Umbridae.

According to Robinson et al. the average age of the central mudminnow is three while they can reach ages of five or six, according to their study in 2009.

Chironoids and gastropods, when taken from the dissection, had a combined volume of about 60 percent which proves that the mudminnow feeds mainly in benthic areas (1984).

The eastern mudminnow, Umbra pygmaea, is a freshwater fish of eastern North America, reaching a length of up to 15 cm.

This mudminnow uses a modified gas bladder to breathe air pockets that are trapped between the ice and water during the winter months to feed and stay active.
