Arapaima gigas

Arapaima gigas reproduce during periods of high water but it is when the water recedes that they dig their nests on a sandy bed. A female lays an average of 47,000 eggs. After hatching, the tiny fish, attracted by a pheromone, remain around the heads of the parents.

Where is the animal to be found?

The arapaima gigas lives in fresh water, in the Amazon River and its large tributaries.

How can it be recognised?

It is often quoted as the largest freshwater fish. It can grow to a maximum size of 5m.

What is distinctive about it?

This fish is also known for its many primitive features such as its bony scales that protect it from being attacked by piranhas. Even though it has gills, the arapaima gigas can breathe air at the surface. This allows it to survive in oxygen-starved, dead water.

Threat and protective measure

The flesh of the arapaima gigas is a source of food and is highly prized by the local population. Its teeth are also used to make jewellery and tools.
