The Curimatidae, toothless characins, are a family of freshwater fishes, of the order Characiformes. They originate from southern Costa Rica to northern Argentina. The family has around 95 species, many of them frequently exploited for human consumption. They are closely related to the Prochilodontidae.
This family lacks jaw teeth, although they do sometimes have small teeth on their pharyngeal plates. They eat films of slime coating underwater surfaces, which consist largely of algae, with some fungi and microscopic animals.
