Arapaima (Arapaima gigas)

Did you know?

That the Arapaima fish is one of the largest freshwater in the world? They can reach lengths of up to 3 meters and a weight of up to 200 kilograms.

The Arapaima can grow to a length of about 2 meters or more, with a weight of 90-130 kg. It has an elongated body, depressed head and a wide mouth. The lower jaw is prominent and has no barbels. They have more than 50 lateral line scales. The scales on the posterior half of the body to the caudal fin are more and more red-lined. The fins are rounded and without elongated rays. The Arapaima’s breathing regularly comes to the surface of the water for respiration (approximately every 10 minutes). 

In adults the back is colored black to steel-blue, the sides are silvery gray and the underside is yellowish gray. Spawning occurs in shallow lakes, especially during the months of October and November. The “incubation by mouth” seems to take place. The parent guards the eggs are known to carry them in your mouth and move to another location. The youth are led by the male in a group, once they are able to swim.
