The Most Massive Animals Roaming Planet Earth

Freshwater Stingray

The freshwater stingray can weigh up to 1,300 pounds. These are the other large creatures found in the Mekong River, often hunted for meat and recreation. Their powerful jaws can easily crush the shells of clams and mussels, and they will occasionally eat small fish. Though docile animals, they are responsible for more injuries to humans each year than any other species in the Amazon.
