How do sloth hairs contribute to their camouflage?

Sloth hairs play a crucial role in their camouflage by allowing algae to thrive on them. This unique relationship between sloths and algae provides an effective form of camouflage. The green color of the algae blends with the surrounding foliage, making it difficult for predators to spot sloths while they hang motionless in the trees.

This adaptation demonstrates the interconnectedness of ecosystems and how various species can evolve traits that benefit one another; in this case, the sloths provide a habitat for the algae, while the algae help conceal the sloths from potential threats. The presence of algae not only aids in camouflage but also introduces an interesting dynamic to the sloths’ habitat.

Other options present different ideas about sloth hairs, such as color-changing abilities, growth patterns, or light reflection, but these do not contribute to the sloth's camouflage in the same effective manner as the algae growth. The reliance on algae highlights how some animals have developed unique strategies for survival that go beyond mere physical appearance.
