Red-bellied Sawtooth Carp

Red-bellied Sawtooth Carp, also known as the piranha, has a terrible reputation and is the most notorious fish in South America, but this is exaggerated. They are known for their frantic feeding, but only in the dry season and when the fish are concentrated in large numbers in a shrinking pond.

Piranhas have highly developed hearing, which is very important in detecting prey. They have sharp teeth that can bite their prey and are extremely sensitive to vibrations in the water. When prey falls into the water, they will rush over and chew it up completely. This process usually takes less than two minutes. It is really bloody.

Arapaima

Dragonfish

Arapaima and dragonfish are both representative fish belonging to the species of Osteoglossus. They only live in the Amazon basin, but because these two fish have high commercial value and are highly ornamental, they are introduced to various parts of the world for breeding. They are currently very popular in the market as ornamental fish, especially some rare dragon fish, which are priceless.

Wild Arapaima is the main source of protein for local Amazon residents because of its high edible value. Due to overfishing by humans, this large freshwater fish has gradually become endangered. Fortunately, the government has issued relevant policies to protect it and strictly control the number of catches. The number has now stabilized.

Amazon Catfish

Amazon catfish is a large catfish and is ranked first in the world's top ten most ferocious freshwater fish. Its body is extremely strong and powerful. It can grow to more than 3 meters long and weigh more than 240 kilograms. The terrifying thing is that it has extremely strong bite force and physical strength. Its spindle-shaped body allows it to migrate fast enough in the turbulent river. Amazon catfish feeds on rotten wood in the water and is a good helper for natural circulation.

Toothpick fish

After talking about the large Amazon catfish, let's talk about the small catfish. The toothpick fish is a terrible fish with a body length of only 2.5 cm. It has its own unique lifestyle. They live in the Amazon basin and can swim into the gills of a larger fish to eat the host's blood. The most terrifying thing is that they can find the host based on the urea content in the water. If someone urinates in the river where he lives, then this demon will quickly find your urethra and drill into it. Just thinking about it makes me shudder.

Because the toothpick fish will be attracted by body fluids, and quickly drill into the human body to suck blood and even eat human tissue, causing severe pain and bleeding, and sometimes even death. Unless surgery is performed, the toothpick fish will not drill out of the human body. Even the locals are frightened and it makes people feel creepy.

Electric eel

Electric eels are native to South America and live in the Amazon River basin. They are not related to real eels, but to freshwater fish and characins. They cannot absorb enough air through their gills and can only breathe air through their mouths. Their bodies are full of blood vessels, which are like lungs. Most of the body of the electric eel is the tail, which is covered with thousands of muscle cells that can discharge electricity. They swim by emitting and detecting weak currents. Large electric eels can emit strong electricity of up to 500 volts to stun their prey, which is enough to stun humans, so it is very unwise to go into the Amazon River.
