If there's one thing we know about nature, it's that it's really weird. Here are 38 animals you might not know about - but won't soon forget.

Tibetan sand fox

This little-known fox is native to parts of Tibet, China and a few other Asian countries. Their behavior is similar to that of other fox species, but they stand out for their unusual facial features.

Long-eared jerboa

This tiny rodent was first caught on film in 2007. They live in parts of China and Mongolia, and it's believed that their ears help them cool off in the desert.

Chevrotain

Also known as mouse-deer, chevrotains live in parts of Asia and Africa. There are several different species, but the smallest ones weigh as little as 4.4 pounds and are the tiniest known ungulates.

Babirusa

These wild pigs are native to Indonesia. Males have unusual upward-curving tusks that actually pierce through the top of their snout; if not worn down, the tusks can actually curve back and into their skull.

Panda ant

These furry creatures are actually wingless wasps - and despite their cute appearance, they pack quite a sting.

Glaucus atlanticus

Commonly known as blue dragons, these tiny sea slugs have been found in warm waters across the world. They float along on water currents and attack prey with a venomous sting.

Honduran white bat

At less than two inches long, these bats would be cute even if they weren't fuzzy. They make tents out of leaves to shelter themselves and their white fur helps them blend into the green glow of the leaves when the sun shines on them. They live in Honduras and other parts of South America.

Shoebill

These prehistoric (and angry) looking birds are found in the swamps of South Sudan and neighboring African countries. Reaching up to five feet in height, they're related to pelicans and use their notable beaks to go after fish, turtles and even small crocodiles.

Leaf-tailed gecko

This unusual gecko is endemic to Madagascar, where it uses its leafy shape to - of course - camouflage. Also known as the satanic leaf-tailed gecko, its scientific name, Uroplatus phantasticus, was chosen because of the creature's unbelievable appearance.

Gelada

Geladas live in the Ethiopian mountains and are the last living species of grass-eating primates. They're noteworthy for their impressive hair coats and the patch of hairless skin on their chests that can be a bright crimson color.

Glass frog

These unusual frogs look normal from the top, but their stomachs are highly translucent. There are several species of glass frogs, which can be found in Mexico and South America.

Golden snub-nosed monkey

This monkey's heavy coat helps it survive the cold mountain climate of central China. They're endangered due to habitat loss and poaching for fur, meat and use in traditional medicine.

Orange tortoise spider

While this rare spider is almost too cute to be real, very little is known about the species except that they live in South America.

Gerenuk

Gerenuk means "giraffe-necked" in Somali and it's easy to see why. These unusual antelope stand on their back legs to feed, allowing them to reach branches and vegetation their short-necked cousins can't get. They're found predominately in Ethiopia, Kenya and Tanzania.

Proboscis monkey

These unusual monkeys are endemic to Borneo, where males use their prominent noses to attract mates. It's believed that their noses create an echo chamber to amplify their mating call. They're unfortunately endangered due to habitat loss from logging and human expansion and are hunted for meat and bezoars, stone-like objects found in their stomachs that are used in traditional Chinese medicine.

Waxy planthopper nymph

This nymph is just one of the thousands of the planthopper insect species, many of which exude colorful, artistic wax displays from special glands. The displays serve several purposes, including protecting them from predators. Species can be found worldwide.

Maned wolf

These long-legged canids (they're not actually wolves) look like a cross between a fox and a deer, and can be found in South America. The hair on their necks can stand erect when they're alert, giving them their namesake manes.
