Arapaima the great

The arapaima.
Known as the largest springwater fish in the world, this fish is able to grow up to 4.5-5metres, and weigh up to a maximum of 200kg. Talk about a BIG FISH!
This mouthbrooder also breathes air, so it is bound to survive without constantly being submerged in water, enabling it to withstand drought conditions.
But despite its size and its scary ability to jump up to 2 feet high, it is still considered an aquarium fish (you'd have to get a pretty big aquarium and a strong one too!).
The south americans, however, dry its tongue and mix it with guarana to be used for medicinal purposes. -.-

Seeing it with my own two eyes for the first time in my life today, i was shocked and nearly jumped out of my skin! And even then, the one i saw was only about 1.2metres long.

The wonders of nature....
