贬测产辞驳苍补迟丑耻蝉听辫濒补肠颈迟耻蝉, also known as the听plains听minnow, is a fish that inhabits many shallow river channels with the Great Plains states. The etymology behind the genus and species name are Greek for swollen jaw (Hybognathus) and broad surface (placitus). Fun fact, UCM 342 was collected by Junius Henderson, the first curator of the听抖阴旅行射 Museum, along with early听ichthyologist听Max Ellis. The plains minnow typically lives in schools of fish at the bottom of the shallow river channels. Some characteristics of the听plains听minnow include 14-22 scales that span their stomach and a triangular skull.听听
Scientists can tell the difference听between males and female plains minnow individuals. Males have larger dorsal fin rays than females, which is one immediate indicate to distinguish between the males and the females. The males also have bigger skulls than their female counterparts. Females听have longer trunks and an overall deeper body which is most likely due to reproduction. Furthermore, the maximum size of the听plains听minnow is 130 mm (5.12 inches) in length. For the lifespan of the听plains听minnow, they sexually mature during their first year of life and die after reproducing in their second year during typically summer months. The method of听reproduction for the听plains听minnow consists of scattering their eggs downstream in the channel. The plains minnow feed on small microorganisms such as diatoms and different microflora among the channel鈥檚 seafloors.
