3The slow-moving sloth spends so much time sitting still that green algae often grows in its fur.

Nature's Children series provides young readers (Ages 8-10) with fascinating information about the planet's most incredible wildlife species. Each title offers a complete picture of the animal- from birth to adulthood- and describes its place in our world, including how humans impact it and its environment. Readers will follow these unique mammals as they use their long, strong limbs to climb through the treetops of South America's jungle habitats. They will also discover what sloths eat, how they raise their young, and why they so rarely spend time on the ground.
