Chelomys megalonyx, or the large long-clawed mouse, is a rodent with very long claws on its front paws. The animal is well adapted for digging deep burrows in the soil of South America.
The large long-clawed mouse differs from other rodents by its very long claws on the front paws, which allow it to dig the ground effectively. It is important for nature because it mixes the soil and serves as food for snakes, birds and other predators.
