The largest freshwater fish are:BelugaSturgeon, this fish can weigh up to tons and can grow up to 7 to 8 meters in length, and is a well-deserved hegemon in the water。Freshwater fish are very common, usually not very large, more than 20 catties belong to the minority. But if there is the world's largest freshwater fish, it is the sturgeon.

In fact, there are many types of sturgeon, such as the Chinese sturgeon.

White snow, tall sturgeon, etc., they all have a common characteristic, that is, they are larger, and among the many sturgeon, the beluga whale cod is the largest.

The body length of an ordinary freshwater fish does not exceed half a meter, while the beluga whale sturgeon can grow to 7 8 meters in length and weigh up to 2,000 kilograms, or tons, which is 4 5 times that of an ordinary adult man. With this height and weight alone, it can already be called the hegemon in freshwater. The main food of beluga whale sturgeon is waterfowl.

Carp and even seals can be a meal on his plate. If you trace the history of the beluga whale cod, it has to start from 100 million years ago, it belongs to the same era as the dinosaurs, and it is amazing how long it has survived.

In particular, the environment is getting worse and worse, destroying the environment on which they live, and finally declared extinct outright in 2019, and since then we can only see this "water tiger" in textbooks.
