Giant mouse discovered to be as big as humans in Amazon

This giant mouse weighs 80kg and is up to 1.5m long. It is the largest rodent that ever lived in South America.

Scientists say it is most likely the ancestor of modern giant water guinea pigs . It inhabits wetlands, which later become lush forests.

With this huge size, they have very few enemies in the wild. It is thought that their rare enemies are large crocodiles, waiting for giant mice to pass by to attack.

They were named biologists Neoepiblema ac Greensis. This species possesses two giant front teeth while the brain is strangely small weighing only about 114 grams.

This can be explained by the good living environment, not many enemies, so they do not need to be too smart.
