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 105 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, zooplankton and detritus.[2] It has been suggested that feeding behavior of some species like Psectrogaster essequibensis may change its diet pattern in function of the sediment content of the water, showing a regime mainly based on algae in waters with high sediment load, until an omnivorous or detritivore regime in waters with low sediment load.[3]
Classification
[edit]Curimatidae contains the following genera:[4]
- Curimata Bosc, 1817
- Curimatella C. H. Eigenmann & R. S. Eigenmann, 1889
- Curimatopsis Steindachner, 1876
- Cyphocharax Fowler, 1906
- Potamorhina Cope, 1878
- Psectrogaster C. H. Eigenmann & R. S. Eigenmann 1889
- Pseudocurimata Fernández-Yépez, 1948
- Steindachnerina Fowler, 1906
In addition, one fossil genus is known in †Plesiocurimata Figueiredo & Costa-Carvalho, 1999 from the Oligocene-aged Tremembé Formation of Brazil.[5]
