Biology:Ichthyoelephas

From HandWiki

Ichthyoelephas is a genus of South American freshwater ray-finned fishes belonging to the family Prochilodontidae, the bocachicos or flannel-mouthed characiformes.[1]

There are two species in the genus: I. humeralis reaches a length of at least 40 cm (1.3 ft) and is found in the Santiago, Chimbo, and Guayas river basins in Ecuador,[2][3] and I. longirostris reaches a length of 80 cm (2.6 ft) and is found in the Cauca–Magdalena river basin in Colombia,[4] and additionally reported from the Rio Ranchería.[3]

They feed on algae and detritus (aufwuchs) that are taken off rocks with their fleshy lips.[5][6] They are commercially important food fish.[5][6]
