Biology:Hemiodontidae
The Hemiodontidae are a small family of freshwater characins found in northern South America, south to the Paraná-Paraguay Basin. The larger species are popular food fish.[1]
Hemiodontids have a streamlined body shape; many are fast-swimming, and are able to leap out of the water to escape predators. The adults of all species except Micromischodus sugillatus have no teeth on their lower jaws. Most species have a round spot on the side of the midbody and a stripe along the lower lobe of the caudal fin. The largest hemiodontids are around 50 cm (20 in) in length.[1]
Fossil remains of Hemiodus are known from the Middle Miocene-aged Pebas Formation of Peru.[2]
