The Sloth Institute


In 2019, The Sloth Institute rescued and rehabilitated 65 sloths. Here are our Top 5 favorite rescue stories of 2019.

Dolly is a two-fingered sloth who was electrocuted and fell from the top of a transformer. She sustained damage to her eye and arm but she recovered surprisingly well. She is the first sloth we’ve tried acupuncture treatment to help with lost motor skills.

The Sloth InstituteHumpty Dumpty’s body was so broken, it was a miracle he survived. Multiple fractures, contusions and neurological issues are no match for his fighting spirit, however—he was climbing trees in no time!

While reuniting an abandoned crying baby with his mother we noticed odd behavior from mom. We brought Mrs. Jumbo and Dumbo in and found a bacterial infection. With care and a very trusting mother sloth, they became well enough to be released and are tracked daily with a collar.

Nemo’s eyes were covered with skin membrane from his eyeballs. His face was full of thorns and was possibly attacked by bees. Stem cells and other treatments allowed us to nally gaze in his sweet, beautiful eyes.

Schumer is not a sloth but a Tamandua anteater. Orphaned at two weeks, she’s now an adolescent and learning skills she’ll need in the wild. She’s named after a certain comedian 😉

What To Do If You See A Sloth In Danger

If you see a sloth who is in need of help, please call or send a message via WhatsApp to The Sloth Institute’s Sloth Response Team at +506 87SLOTHS. Ideally it is best to send photos or a video of the sloth in need of rescue. The TSI Sloth Response Team can then properly assess the situation. There are times we get a call about a sloth in danger when they aren’t in need of rescue.

You can also call your local Bomberos (Fire Department). If a sloth is on the electric wires you can also call ICE.
