Pale-throated Three-toed Sloth
The Pale-throated Three-toed Sloth (Bradypus tridactylus) is a three-toed sloth that inhabits tropical rainforests from southern Central America to northeastern Argentina. This sloth lives high in the canopy.
It has almost no tail or external ears. Its head is slightly rounded with a blunt nose. The body is covered with long and course hair. Very small green algae sometimes live in the pits of the hair, which gives the sloth an overall greenish appearance that serves as camouflage. Male sloths have a bright yellow or orange patch on the back. The females have two mammary glands in the chest region. The three-toed sloth is armed with long, compressed, arched, hollowed claws. The middle claw is the largest.
Bradypus tridactylus grows to a length of between 1.5 and 2.5 ft. The limbs are long and weak. The anterior extremities are nearly double the length of the posterior. The three-toed sloth has 9 neck vertebrae, giving it extreme flexibility.
The three-toed sloth can hang so securely with its hook like claws that it even falls asleep in this position. A sloth may even stay suspended in the trees for some time after it dies.
