25 strangest creatures on Earth that you probably don't know

With more than 8 million species of living things on Earth, no wonder that nobody knows or has seen them all.

And with scientists discovering new rare animal species almost every day, this operation sounds quite unrealistic. That's why we've chosen the most curious and weirdest animals of the bunch, so you won't have to spend a decade checking them out yourself.
