The paiche, also known as arapaima, is an iconic fish from the Amazon basin that has captured the attention of both scientists and sport fishers. This fish stands out not only for its large size but also for its extraordinary adaptation to the dynamic environment of the Amazon rivers. In this blog, we’ll reveal some of the most interesting facts about the paiche that are sure to surprise you.
The Giant of the Amazon
The paiche is famous for being one of the largest freshwater fish in the world. It can reach lengths of up to 3 meters (10 feet) and weigh over 200 kilograms (440 pounds). Its size gives it a dominant position in the food chain, capable of hunting everything from small fish to birds that accidentally fall into the water.
A Fish That Breathes Air
Unlike many fish that rely solely on dissolved oxygen in the water, the paiche, an Amazonian fish, has a modified swim bladder that functions as a primitive lung. This allows it to surface every 20 minutes to breathe air. One of the most fascinating facts about the paiche is its ability to adapt to environments with low oxygen levels, enabling it to survive where other fish cannot.

An Almost Indestructible Skin
One standout fact about the paiche is its incredibly tough skin. It’s so durable that people in the Amazon traditionally use it to make protective shields. This skin is made up of a layer of thick, hard scales, protecting the fish from predator attacks, including piranhas.
Hunting and Feeding Behavior
Despite its size, the paiche is a stealthy hunter. It uses its impressive size to set up powerful ambushes. Swimming near the surface, it detects its prey with smooth, quick movements. When it finds its target, it swiftly sucks in the unsuspecting fish or bird with incredible force.

Importance in Local Culture
In many Amazonian communities, the paiche is not only an important food resource but also a cultural symbol. Its meat is prized for its mild flavor and low fat content, and its fishing poses a challenge for sport fishers due to its size and strength.
The paiche is not just a giant of the Amazon rivers but also an incredibly well-adapted fish full of fascinating curiosities. Its ability to breathe air, its imposing size, and its capacity to survive in extreme environments make it one of the most intriguing species in the Amazon. As conservation efforts grow, it’s essential to recognize the importance of this species and its contribution to biodiversity.
