The slowest mammals on earth, sloths were born to be tree-dwellers. Sloth mothers give birth while hanging upside down! With their long, sharp, curved claws, baby sloths spend their days clinging to tree branches in the rain forest. They make their way down from the trees only once a week for a bathroom break, which makes them vulnerable to predation. Readers will enjoy an accessible yet informative look into how baby sloths grow up. Amazing full-color photographs will fascinate animal lovers while fast facts and words to know sections extend the learning experience.
