The animal known for its slow movement and shell is the sloth. Sloths are native to Central and South America, primarily found in tropical rainforests. These creatures are renowned for their extremely slow pace, often moving at a speed of just 0.03 miles per hour. Sloths are well adapted to a life spent hanging upside down in trees, where they feed on leaves, fruits, and flowers. Their slow movement is an evolutionary adaptation that helps them conserve energy and avoid detection by predators. Additionally, sloths have a unique algae ecosystem growing on their fur, which provides them with camouflage.
