What Is An Arapaima?
An arapaima is considered to be the largest freshwater fish. This fish is also known as pirarucu. The scientific name of it is Arapaima gigas. This fish is the natural habitat of Brazil and Guiana. It may be of length of some 16.5 ft as well. Apparently an arapaima looks like an ancient creature – asymmetrical tail fin and a swim bladder functioning as an air-breathing appendage make an arapaima to exhibit as an outmoded phenomenon. Arapaima feeds fishes by pressing and grinding them using their strong jaws, and sometimes ravening among the school of fishes when abundant in numbers. One important feature is observed during reproduction – that is, colour change. At the mating time, adult arapaima gets paired and both of them actively participate in hollowing out to lay eggs. In general, this hole is made in light water and surrounded sufficiently by vegetation. The young arapaima stays close to its parents all the time until it learns how to protect itself from its predators.
