Why does moss grow on manatees skin?

Moss and other epiphytic organisms can grow on manatees' skin because their slow-moving, aquatic lifestyle provides a suitable environment for these organisms to attach and thrive. The warm, shallow waters where manatees often reside can promote growth, and the rough texture of their skin offers a favorable surface for moss to cling to. Additionally, the algae and other microorganisms present in their habitat can contribute to the growth of moss. While this growth is generally harmless, it can indicate the health of the manatee and its environment.
