Heart-Melting Pictures of Cute Sloths Who Just Want to Be Your Friend

These baby sloths raise cute to a whole new level.

The healing power of sloths

Sam Trull

“Loving sloths saved my life,” says writer/photographer Sam Trull in her book Slothlove. In an effort to move on with her life after painful personal losses, she went to Costa Rica three years ago to volunteer at a wildlife rehabilitation clinic run by the nonprofit Kids Saving The Rainforest (KTSR). Trull, a primatologist, was drawn to Costa Rica to work with the country’s monkey species, but at KTSR, she ended up falling hard for sloths. Can you blame her? Here, a sloth called Keychain peeks out of a cup.

Chuck: A curiously snuggly sloth

Sam Trull

This orphaned sloth was brought to KSTR when he was a couple of weeks old. It’s not known what killed his mother but possible threats include dogs, cars, electric wires, or deforestation. Due to his “crazy hair and sweet disposition,” Trull named him Chuck after her late father. Like others in his species, Chuck loves to cuddle. In the wild, sloths spend their early months holding on to their moms, so at KTSR, orphans are given stuffed animals to grip onto.

Kermie: Three toes, two fingers

Sam Trull

The common terms used are two-toed sloths and three-toed sloths, but those are misleading, says Trull. In fact, all sloths have three toes, but they have either two or three fingers on their “hands.” Kermie, here, is a two-fingered sloth, and this variety is near-sighted and nocturnal. Although their diet is primarily plant-based, sloths also eat eggs, insects, and small invertebrates.

Kermie and Ellen: Barefoot and fancy-free

Sam Trull

Three-fingered sloths have hair everywhere except for their noses. Two-fingered sloths like Kermie are hairless on their faces, palms, and soles of their feet. Kermie was the first first newborn sloth that the author cared for and the first of her charges to be released into the wild. In the fall of 2015, he was placed in a wilderness area in a large soft cage (along with a sloth named Ellen). This was so that they could adjust to the temperature, smells, and sounds of their new home. Food was still provided daily by KTSR staff, and after a while, the door to their cage was opened. Both Kermie and Ellen wear radio collars, so Trull can keep know where they roam.

Tiny: Secret of the sloth smile

Sam Trull

Here, Tiny, shows off his best sloth grin. Sloths always look like they’re smiling because that's the natural configuration of their facial muscles. Still, you can tell that a sloth is in a good mood when it is stretched out, showing it’s relaxed. Tiny’s claws are transparent because he’s very young, but they will become an eggshell color when he matures.

Monster: Trull's "slothy soulmate"

Sam Trull

Although moms aren’t supposed to have favorites (and that goes for sloth moms, too) Trull will admit that Monster, here, holds an extra-special place in her heart. Monster was taken in by KTSR when she was just two weeks old. Sloths that young need to be fed every two hours, and Trull carried Monster wrapped to her chest to provide comfort.

Monster: Munching on hibiscus

Sam Trull

Monster, like other three-fingered sloths, is a herbivore. Her favorite foods are hibiscus flowers, cinnamon leaves, and guarumo fruit. In February 2016, she and another sloth, Piper, were released into the wild, but they are being monitored via radio collar by Trull and her staff.

A sloth society

Sam Trull

Scientists have reported that sloths are solitary creatures, but Trull believes their finding may be due to the fact that in the wild, the animals can be hard to observe closely. At the Sloth Institute, Trull's orphans show distinct preferences for one another.

Chuck: up in the air

Here, Chuck hangs from a tree. Sloths typically spend most of their time in trees, but they are also excellent swimmers.

Pelota: Trull's first sloth

Sam Trull

Pelota, here, was “the first sloth I ever met. The first sloth I ever held. The first sloth I ever held. The first sloth I ever fed," writes Trull on the Sloth Institute blog. "The first sloth that I lost sleep for. The first sloth that made me proud. And … the first sloth I ever loved." Sadly, Pelota was a thriving two-and-a-half-year-old when she died from a venomous snakebite.

Locket and Elvis: Hairy hug

Sam Trull

Locket (left) and Elvis embrace, here. Locket, a three-fingered sloth, was found with his umbilical cord still wrapped around him. Two-fingered Elvis was not much older than that when he arrived at KTSR. Although Elvis is small in this photo, he will outgrow his friend: adult two-fingered sloths average 13 pounds; three-fingered sloths, 9 pounds.

Why help sloths? “Without animals, we would have no forests, and if we had no forests we would die,” Sam Trull said in an interview. “Everybody is interconnected, and we need each other to survive. So if we don’t care about what’s going on with the animals in the forests, then we’re basically saying that we don’t care about ourselves.” While Trull and her staff have bonded closely with the sloths in their care, Trull cautions that they do not make good pets. They are extremely high maintenance, and they have a vicious bite.
