Most of us don’t grasp the variety of animals species that inhabit the Earth today, and some even get surprised as they find out there’s an animal they haven’t heard of before. But seriously now – out of 1,367,555 identified non-insect animal species that live on Earth today, how do you expect to know every single one of them? Inspired by reddit, we put together a selection of 22 animals you probably didn’t know existed.

Dutch artist Florentijn Hofman goes big – so big, that it’s practically impossible to miss his artistic statements. His latest work is a 46 feet tall and 55 feet long inflatable rubber duck, which today arrived to Hong Kong’s Victoria Harbour and will stay there till June 9. Boldly called the Rubber Duck, this floating sculpture is described by Florentijn as a “very positive artistic statement that immediately connects people to their childhood”.

Eastern Europeans must have altered adrenaline glands! It hasn’t been long since we shared heart-stopping photos of Russian skywalkers, and this time it’s a former legal adviser Pavel from Ukraine that stops traffic and leaves people in awe. A 26-year-old rooftopper from Kiev, better known as Mustang Wanted, has shocked the world with the pictures of him holding on to various high-rise building with just one hand. It’s hard to believe, but Pavel doesn’t use any safety gear nor ropes.

National Geographic photographer Joe McNally snapped a shot that some call “the mother of all rooftopping photos.” Standing atop the Burj Khalifa, the world’s tallest building, Joe shared this amazing photo on Instagram from about 820 meters high!

While the humans have been looking for the elixir of life throughout every period of history, it appears that there is one species of jellyfish that are actually immortal. Turritopsis nutricula, or sometimes – Turritopsis dohrnii, is able to transform its cells from mature state back to immaturity, in other words – back to youth. The medusa leads a regular cycle of life, but after maturing and mating, it reverts back to its initial state – a polyp colony. The process is referred to as “transdifferentiation”, and it basically makes the jellyfish unable to die.

If you feel like you could use some inspiration to design your future home – or just like checking out the weird ideas some people have – this post is just for you! Would you choose to live in a former church, or a renovated water tower? Or how about a completely transparent house, or one that is a spitting image of the Flintstones’ cave? Check out our selection of world’s weirdest houses and share your thoughts in the comments!

This cold storage facility in Chicago may not draw your attention from the outside, but had you entered the building a few months ago, you’d be surprised to see what was inside. After nine decades of cold storage and lack of proper maintenance, the whole interior was full of cave-like stalagmites and stalactites. Once the Fulton Market Cold Storage Company, which was renting the premises, decided to move out, it was sold to a bike component manufacturer SRAM. However, in order to use their new space, SRAM had to defrost the building first.

If you’re torn between wearing fur and loving animals, the dispute has already been settled. The pictures by French photographer Erwan Fichou prove that you only have to love your pet long enough… to be able to wear it later! The dog owners in the photos would pet their buddies so much that they could collect enough of their fur to spun it into yarn and knit a sweater from it.

When, due to his feet injuries, British engineer Simon Beck could no longer run, he decided to get some exercise by taking long walks. To make it more interesting, 54-year-old would put on his snowshoes and walk in distinctly geometric patterns. Step by step, after 8 to 10 hours of walking it creates some jaw-dropping trampled snow art.

Be it climbing up as high as a 380-meter crane or a 22-storey building – two young Russians have got it all, and more, on their cameras. Vitaly Raskalov and Alexander Remnov call themselves skywalkers, and take pictures of each other on top of the highest buildings in Moscow and some other cities in Russia. The crazy skywalking pictures make you dizzy just by looking at them!

Finally, justice was served, and twittering was given back to the original source – the birds! Latvian conceptual artist and creative director Voldemars Dudums created a system for birds to type Twitter status updates: all he needed was a three-euro keyboard and some unsalted fat, attached to the keys with stainless steel screws. By eating off the fat, the birds would hit the keys with their beaks and post online!

In order to build a new road, the Chinese government had to move a village of over 1000 people – two, however, said they would stay till the bitter end and didn’t leave. It wouldn’t be a big deal, only now their house stands alone in the middle of a new motorway of Xiayangzhang village in the province of Zhejiang. The phenomenon of a lone house that wasn’t torn down due to the constructions is called a “nail house” in China, referring to the image of an ingrown nail that’s painful and almost unable to remove.
