Ripsaw catfish

the ripsaw catfish or cuiu cuiu, is a species of thorny catfish native to the AmazonEssequibo and São Francisco basins in BoliviaBrazilColombiaEcuadorGuyanaPeru and Venezuela. It is the largest member of the Dorididae family

Ecology

Ripsaw catfish have been found in water with temperatures ranging from 24-29.8 °C, a pH range of 5–9, and an alkalinity range of 42–142. This species feeds on detrituschironomid and ephemeropteran larvae, and crustaceans. They are known to form schools

They typically inhabit muddy streams and lakes. During the rainy season, ripsaw catfish often migrate to large freshwater lakes and flooded basins, returning to their main river when floods recede. They are native to the Amazon River and have been found on the east coast of South America. Due to the size of the Amazon River, as well as the rainy season expansion of their habitat, they have been found across wide areas. This has allowed them to survive.
