r/sloths

Sloths can hold their breath underwater for up to 40 minutes.

Dolphins, on the other hand, need to come up for air after about 10 minutes.

This means a sloth—the poster child for doing absolutely nothing—can easily out-swim and out-hold-its-breath a dolphin simply by slowing down its heart rate to a near-dead stop. Slow and steady literally wins the aquatic race.
