Brown-throated sloth

The Bradypus variegatus (Brown-throated Sloth) currently lives in the tropical rainforests of Central and South America. These rainforests are densely packed with lush trees and are moist, humid environments with a heavy annual rainfall, often exceeding 100 inches. Sloths are adapted to these rainforests with their long, curved claws, coarse fur that can appear green due to algae growth, a multi-chambered stomach that helps them digest fibrous leaves, and more. However, in about a hundred years, the rainforest is predicted to change into a savanna, a yellow-colored, subtropical grassland biome known for its continuous carpet of grasses, intense dry seasons, scattered trees, and woody shrubs. The brown-throated sloth is not suited for a savanna-like environment, so over a very long time, drastic changes would need to be made: a new diet, yellow-tinted fur to blend in with the colors of the savanna, burrowing behaviors, even higher energy conservation and more.
