Титикака
The Titicaca orestias, Lake Titicaca orestias, or Lake Titicaca flat-headed fish ("Orestias cuvieri"), also known by its native name amanto, is a likely extinct freshwater killifish from Lake Titicaca in South America. It belongs in the pupfish genus "Orestias", endemic to lakes, rivers and streams in the Andean highlands. With a total length of up to , it was the largest member in that genus. In the hope that an undiscovered population remains, it is listed as Data Deficient by the IUCN. Despite its common name, it is not the only "Orestias" from Lake Titicaca.
