Black Howler Monkey

Living in extended family groups, howler monkeys spend most of the day feasting on leaves in the treetops. As a group, they howl to defend their territory. The howling is so loud and deep that it can be heard from nearly two miles away, thanks to a deep jaw and specialized voice box.

White-bearded Wildebeest

The wildebeest is known for its annual migration across the plains of Africa in search of greener pastures. Up to 1.5 million of these large antelopes travel over 1,800 miles every year. Hundreds of thousands of wildebeest fall prey along the way to lions, hyenas and other predators that follow the herds.

Hippopotamus

Hippos spend the majority of the day soaking in water or mud to keep their skin moist and bodies cool. When submerged, just their eyes, ears and nostrils stick out of the water so they can still see, hear and smell what’s going on around them. At night, they come out to munch on grass.

White-Faced Saki

It’s easy to tell whether an adult white-faced saki monkey is male or female. The males are all black except for the white fur around their faces while the females are overall brown.

 

Cape Porcupine

When threatened, the Cape porcupine erects its spines and quills to look bigger. Contrary to popular belief, a porcupine cannot shoot its spines and quills. However, the spines and quills can embed in an intruder’s flesh if they come into contact. The porcupine grows new spines and quills to replace those that are lost.

Southern Tamandua

Also called the lesser anteater, the tamandua uses its long snout to sniff out ant, termite and bee colonies. Long claws enable it to dig into nests, and a long sticky tongue licks up the insects. A single tamandua can eat up to 9,000 ants in a single day!

Golden-headed Lion Tamarin

Golden-headed lion tamarins are tree-dwelling monkeys that live in small social groups with a single breeding female. Offspring often remain in the group as they mature to help raise their younger siblings, thereby sacrificing their own reproductive opportunities.

Screaming Hairy Armadillo

As its name implies, the screaming hairy armadillo squeals when threatened, perhaps by a hungry jaguar. Resting inside a burrow dug deep into a sand dune, it escapes the heat of a summer day. In winter, the armadillo is more active during the day.

Capybara

The capybara lives in a social group of 10 or more led by a dominant male. Males mark their territory by rubbing a scent gland on top of its snout, called the morillo, onto vegetation. With slightly webbed toes, the capybara is an excellent swimmer and often rushes into the water to escape predators.

Meerkat

Like other mongooses, meerkats spend the night in a burrow. In the early morning, they stand tall on their hind legs, exposing their bellies to the sun to warm up before the day’s foraging activities can begin. A nearly bald patch of darker skin acts like a solar panel to soak up the sun’s rays.

It’s fascinating to watch the meerkats work together. While the rest of the mob scurries about rustling up grub, they take turns standing tall on…
