Read the Latest Sloth Science News
The Sloth Institute is one of the few organizations in the world conducting and publishing peer-reviewed sloth science directly from the field. Based in Manuel Antonio, Costa Rica, our research team, including veterinarians, biologists, and wildlife rehabilitation specialists, investigates sloth biology, cardiac anatomy, anthropogenic threats, and rehabilitation medicine to advance the clinical care and long-term conservation of both sloth species found in Costa Rica: Bradypus variegatus and Choloepus hoffmanni.
This Sloth Science Journal brings together our published studies, press releases, and conservation reporting, making sloth research accessible to scientists, biologists, veterinarians, and sloth lovers!
