Three-Toed Sloth, Costa RicaThe three-toed sloth, also known as the brown-throated or three-fingered sloth, spends most of its life hanging upside down in the rainforest canopy, moving so slowly that algae actually grows on its fur, helping it blend into the greenery. They sleep most of the day, but I caught this guy up and at it. Well, sort of. Nikon Z8 with Nikkor 500mm PF lens, ISO 220, f/5.6 at 1/125th of a second.
