What is a Finger Monkey?
The arapaima gigas also known as the paiche or pirarucu is a true river monster. One of the world’s largest fresh water fish, they are known to reach up to 10 feet (3 meters) in length and perhaps even weighing in excess of 400 lb (180 kg). This species is also one of the rare air-breathing fish in existence which means it needs to come up to the surface to breathe.
