It’s not a secret we’re living in a world filled with amazing creatures, but in our everyday lives we tend to forget just how peculiar and versatile the animal world can be. Some of the creatures have extra big ears or noses, while others are completely transparent, allowing us to observe what’s happening inside their bodies. Nature’s imagination has no end, and sometimes the result is more than just mind-boggling – there are animals that look like they’ve come from another world! Here are 10 times Nature went over the top to impress us, and it worked. The greater sage-grouse is one stylish fella. He wears a chic fluffy white collar endowed with two big bright-yellow sacs. Like everything in nature those two have a purpose – they get inflated to attract the female during courtship displays.Meet aye-aye, a long-fingered lemur and the only nocturnal primate you’ll find in Madagascar. He may not look like it, but he’s in close relation to chimpanzees and humans!Pink fairy armadillo is the cutest out of all armadillos and maybe animals in general. Living mostly in the grasslands and sandy dunes of Argentina, this species of armadillo is active during the night, hunting for insects or munching plants. It’s already on the list of endangered species!When looking at okapi it’s hard to tell what animal are looking at exactly – it has stripes like a zebra and it’s built like a horse, when in fact it’s closer to giraffes than any other animals! Okapi dines on grass, plants, and various other greens.Pacu fish will certainly surprise you once you take a sneak peek inside its mouth – there are teeth that look just like human’s! No wonder, because pacu fish is closely related to piranha, but unlike its meat-eating relative it mostly eats nuts and seeds.
