These petite and impossibly slow sloths have found that the ocean offers a quick and safe way to get around.
It’s not easy being the slowest mammal in the world. While a cheetah can go from 0 to 60 miles an hour in only three seconds, it takes a sloth all day to cover 41 yards. Sloths are r-e-a-l-l-y slow.
But in the turquoise waters off the coast of Panama, a group of pygmy three-toed sloths (Bradypus pygmaeus) have found an alternative, and quicker, mode of transportation: Swimming! As you can see on the following pages.
“If they have to change trees, they just plop into the water,” says Becky Cliffe, a British zoologist and founder of the Sloth Conservation Foundation. “They’d rather swim than crawl on the ground.”
Discovered in 2001, these compact cuties are found only on a small island 10 miles from the mainland. And while they’re not the only sloths to swim, they are the only sloths known to swim in seawater. In addition, writes Hillary Rosner at bioGraphic “these diminutive tree-dwellers seem to swim far more frequently than their larger cousins, placidly paddling with just their flat-snouted, hairy heads protruding from the turquoise sea."
As it turns out, the sloths’ diet of leaves leads to the generation of gas during digestion, which means “they’re like big balls of air,” Cliffe says, which makes them relatively buoyant and makes swimming easy. And in fact, they can swim three times faster than they can move through the trees. How amazing to see these dedicated canopy dwellers take to the sea. They may be slow by nature, but they've found a way to game the system.
