Brought into Colombia as exotic pets by the most notorious drug kingpin in human history, have been breeding at an alarming pace over the last few decades and have become a serious threat to the Colombian flora and fauna.

In the 1980s, Pablo Escobar smuggled four hippos from an American zoo into Colombia, as exotic pets. They were kept at his luxurious Hacienda Napoles, in Puerto Triunfo, Antioquia, but after the collapse of his crime empire, they were set loose into the jungle. With no natural predators, plenty of water sources and suitable climate, the hippopotamuses thrived and multiplied. The initial four water giants have now ballooned to an estimated population of over 100, which scientists say could reach over 1,400 specimens by 2039.

Despite having round anuses like all other mammals, bare-nosed wombats do not produce round pellets, tubular coils or messy piles; they are the only creature on Earth that poops cubes.

Wombats, marsupials native to the grassy plains and eucalyptus forests of Australia, are among the most adorable animals in the world, but to animal experts they have been a tough-to-solve mystery for a very long time. And it has all been because of their poop. You see, wombats have the unique ability to produce up to 100 distinctive, cuboid pieces of poop every day. Now, researchers say they have uncovered how the wombat intestine creates this unusually-shaped excrement.

The Common Baron Caterpillar is a true master of camouflage. When it positions itself perfectly on a mango tree leaf, it is nearly impossible to spot, even if you know it’s there.

Some animals naturally develop camouflage in order to make themselves harder to spot by predators, but some are much better than others, and some blend into their natural surroundings perfectly. The Common Baron Caterpillar (Euthalia aconthea), a critter native to India and Southeast Asia, fits in the latter category. It has evolved to blend into its preferred background so well that it is nearly impossible to see.

Black egrets, a species of African herons, have a very unique hunting technique – they use their wings to from an umbrella, which not only reduces glare, but also lures fish into false sense of security.

Called “canopy feeding”, the hunting technique used by black herons has to be one of the sneakiest observed in the wild. The black wading bird walks about slowly through shallow water and then spreads its wings around its body, to create an umbrella of sorts that blocks out the light. Although it’s not perfectly clear why the African heron uses this specific technique, scientists hypothesize that it has several advantages, like reducing glare and attracting the fish into a trap.

Poltys mouhoti, aka the Rolled-up Leaf Spider, is a fascinating arachnid that uses incredible camouflage to protect itself from predators during the day.

Native to Vietnam, but also spotted in other Asian countries like Cambodia, Thailand or Malaysia, the aptly-named rolled-up leaf spider is part of the Poltys genus of spiders, which numbers 43 known sub-species, most of which have this amazing ability to mimic plant parts as a self-defense mechanism. They accomplish this by tucking their legs in towards their abdomen, and extending a long, stem-like appendage outward. Even their body has a brown and green coloration and a shape reminiscent of a broken branch, which enhances the camouflage even more.

Serama chickens are the smallest in the world, but you really couldn’t tell by their attitude. Seeing them pose with their head pulled back and chest sticking out, you’d think they were some sort of feathered bodybuilders.

The Serama chicken breed can be traced back all the way to the 1600s, to the Kelantan province of Malaysia, but the current strain can be attributed to Wee Yean Een, a breeder who popularized it during the 1970s and even gave the chicken the Serama name, after King Rama of Thailand. However, the breed was rendered almost extinct by the bird flu pandemic of the early 2000s. Luckily, they had already been exported to many countries around the world by that point, including the US and UK, and were able to make a comeback.

Mao Mao, a two-year-old British Shorthair from Chongqing, China, works as a professional cat model and earns between 5,000 yuan ($775) and 10,000 yuan (1,550) per appearance.

Her owner, a man surnamed Zheng, works in the automotive industry, and during an auto show he had the brilliant idea of putting his pet cat into one of the cars.

Nowadays, the cat is a household name at auto shows and routinely lands a few appearances per month.

Male and female Northern Flickers are popularly known as “machine gun woodpeckers” because of the sound they make when hitting their beak on metal, which sounds a lot like the sound of a real machine gun.

The Northern Flicker is a woodpecker native to most of North America, parts of Central America, Cuba, and the Cayman Islands. It is 7 to 15 inches long , with a brown, barred back and black spotted under-parts. From early spring and into midsummer, this bird likes to make its presence felt by making a loud, evenly spaced, rapid drumming sound by hammering their beaks against metallic surfaces. This sound is both a mating call and a way to establish territory, but to the human ear it sounds just like a machinegun, hence the bird’s nickname, machine gun woodpecker.

The caterpillar of the rare pink underwing moth has a very peculiar defense mechanism. When disturbed, it suddenly arches its back to reveal a pair of large, frightening eyes and what looks like a two rows of barred teeth.

The pink underwing moth is a rare and enigmatic insect found from subtropical New South Wales through Queensland and New Guinea. It feeds on rotting fruit and, although nocturnal, doesn’t seem to be strongly attracted to light. The moth’s name was inspired by the bright pink bars on its hidden hind underwings, which some experts believe act as a defense mechanism. The theory is that a sudden display of color can startle or surprise a predator for long enough to let the moth escape. But that defense strategy pales in comparison to that used by the pink underwing moth in caterpillar form.
