The slowest animal in the world is typically considered to be the three-toed sloth. These sloths move at an average speed of about 0.24 kilometers (0.15 miles) per hour. They are known for their slow movements, both on land and in trees, due to their low metabolic rate and unique muscle structure. This slow pace helps them conserve energy, which is essential for their survival, as they primarily eat leaves that provide minimal energy.Another extremely slow animal is the garden snail, which can move at a pace of around 0.03 miles per hour. However, the sloth is still considered slower overall when looking at larger distances or typical movement in their natural habitats.
