What is ribsaw catfish?

As an AI language model, the information I provide is limited to what is available publicly. Here is what I could find:

The ribsaw catfish, scientifically known as Pseudoplatystoma fasciatum, is a large freshwater fish native to South America, primarily found in the Amazon and Orinoco basins. It is also known as the barred sorubim, barred catfish, or tucunaré in Brazil.

Ribsaw catfish can grow up to 1.5 meters (4.9 feet) long and weigh up to 70 kg (154 lbs). They have a grayish or olive-green body with dark crossbars or bars on the sides and back. They have a flattened head and wide mouth with sharp teeth.

The ribsaw catfish is a predatory fish and feeds on other fish, crustaceans, and other small aquatic animals. They are also an important commercial and recreational fish species and are widely farmed in South America for food. However, overfishing and the destruction of their natural habitats have led to a decline in their populations in some areas.
