If a brave SCUBA diver wishes to explore the dark and murky waters of the Amazon, they are sure to encounter a number of strange fish. Some, like the infamous, flesh-eating piranha, are well-known and should be avoided when possible. Other are spectacular and strange due to their habits and appearance. Here are just five unusual species residing in the Amazon River and its tributaries that would make interesting characters to see on a dive.
Peacock Bass
The Tucunaré peacock bass is a brightly colored fish that populates rocky substrates in the calmer waters of the Amazon. These bass are distinguished from all other fish in the Cichla species by spectacular rainbow bands that are not seen in other bass of this genus. These bass grow to 30 inches in length, forming vibrant schools with flashing colors, making them an ideal subject for underwater photography.
Arapaima
Divers will need to go deep into the wilds of the Amazon to catch a glimpse of this strange fish. Found only in the Amazon River basin, the Arapaima, also known as the Pirarucu, is one of the largest freshwater fish in the world, growing to nearly 15-feet in length and weighing more than 400-pounds. This fish is an obligate air breather. It rises to the surface and audibly grunts for air, a noise which can be heard for a good distance.
Wolf Fish
This ferocious-looking denizen of the Amazon’s tributaries has a fierce reputation for biting people. The lacerdae species can grow to 40-inches in length and weigh 20 pounds. They have sharp, round teeth and steel jaws.
Electric Eel
These fish are closely related to catfish and can deliver a shock of 600 watts, which is enough to knock out a grown man. Multiple shocks can cause respiratory failure. They hang out in the same domain as a catfish.
Payara (Vampire Fish)
These strange fish are obviously named in reference to their large, vampire-like teeth. At about four feet in length, Amazonians consider this the most ferocious fish for its size. Two giant fangs grow from its lower jaws which can reach six inches in length. It feeds on piranhas — just a hint at how tough it is in case you were curious.
