What is "phenacobius"

Phenacobius mirabilis, the suckermouth minnows, is a genus of cyprinid fishes endemic to the United States. Historically the suckermouth minnow was not found as far eastward as Ohio, now they seem to be a stable species living throughout the Midwest and parts of southern states such as Texas, New Mexico, and Alabama. Many forests and prairies were cleared out to make farmland, this caused for drainage streams and rivers to take form, moving the minnows eastward. Originally the suckermouth minnows probably never crossed the Mississippi River prior to the developed farm land.They have a lifespan of roughly 3-5 years, but is hard to measure due to predation, survival rate of about 50 percent. There are currently five described species. Etymologically, "phenacobius" means "deceptive life", possibly because these species eat insects despite an herbivorous appearance.
