Paracetopsis bleekeri is a small freshwater fish from the family of whale catfishes. It lives in the rivers of the Amazon basin and hunts small animals in dark water.
Paracetopsis bleekeri differs from other catfishes by its elongated scaleless body and special barbels for hunting in the dark. It is important for nature because it helps control the population of small animals in the rivers of Amazonia.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
