The Arapaima is grey and has a reddish orange color along its belly and underside. They mostly eat other fish, but arapaima will also eat birds and any other animal that it can catch. Part of what makes an arapaima so unusual, besides its size, is that it needs oxygen from the air to survive.
Arapaima fish have built in sacks, or air bladders, that can fill with air as the fish takes a gulp of air from the water's surface. The sacks help the arapaima float well, or create buoyancy. The lung-like bladders are an advantage in the Amazon River because the river's water does not have much oxygen. This fish is able to survive extensive drought periods by gulping air and burrowing into the mud or sand of the swamps.
Arapaima scales are used as tools in the rainforest.
Arapaima are smaller today than they were in the past is because of over-fishing. Over half of the giant fish is made up of meat, which makes it a very popular fish for people to eat.
Scales can be used as nail files.
