Hang in there. Slow down for a moment of #NatZooZen with two-toed sloth Athena and her kale. Two-toed sloths are native to Central and South America and live in the canopies of tropical rainforests. They are very slow moving and have a metabolic rate of about 40% to 45% of what would be expected for their body weight. Their body temperatures range between 86 to 93 degrees Fahrenheit, which helps them conserve energy.
