The giant fish, known as the Mekong river monster, is in danger of extinction because of the destructive fishing behavior of humans.

Although this large fish was known by locals as sea monster many centuries ago, scientists know very little about them. Photo: Facebook/Sportex Italia.

Currently, Mekong giant catfish very rarely appear. Scientists have not yet determined their habitation area as well as their living habits. Photo: Boredom Therapy.

Due to over-hunting, the fish only exists in small schools in the central region of the Mekong River. Photo: Boredom Therapy.

They grow very quickly. Adults can reach nearly 350 kg in weight and over three meters long. Photo: National Geographic/Zeb Hogan.

Due to their large size and weight, the Mekong giant catfish is among the largest freshwater fish in the world. Photo: Facebook.

The food of this fish is quite strange. In their first years of life, they eat only plankton. As adults, they mainly feed on algae growing on submerged rocks and sometimes even pigeons. Photo: WordPress.

The Mekong giant catfish is listed as critically endangered, with numbers declining by more than 80% in the past 14 years. Photo: WordPress.

If the authorities do not take tough measures to protect them in time, the Mekong giant catfish may remain a legend. Photo: WordPress.
