Bechleja rostrata is a freshwater variety of shrimp from the family Palaemonidae. Today palaemonids are ecologically diverse, with some species living in freshwater and some living in marine environments. They are true shrimp, but are sometimes called "prawns." Bechleja rostrata was probably an important food source for several fish species that possessed dentitions suited for crushing arthropods such as stingrays like Heliobatis and Asterotrygon.
