This sloth hangs from a tree.


Sloth Surprises One day, Avey-Arroyo walked into the room. Buttercup turned to see her. Buttercup turned her head almost all the way around. T at really surprised Avey-Arroyo. Most mammals can’t do that.


Sloths can. T ey have extra bones in their necks. T is is helpful in the wild. Here is why. When a predator is near, a sloth


doesn’t move its body. It just turns its head to see. T e movement makes no noise, so predators can’t hear it. T at helps keep the sloth safe.


T is wasn’t the only sloth surprise


for Avey-Arroyo. Buttercup’s fur looked green. It was covered in algae. Algae help sloths blend in with the


trees. Without it, predators can spot sloths easily. Buttercup’s algae soon disappeared in her new home. She didn’t need it.


Curved claws help a sloth climb and cling to branches.
