Could you imagine the world without tigers or African elephants in the wild? These are just two of the many animals that could go extinct in the while within the next hundred years, thanks in part to habitat loss, hunting, fishing, and disease.
There are animals with badass names, and then there's the Ozark Hellbender. This salamander-like creature might sound like a reject from a particularly gritty and/or rural episode of Avatar: The Last Airbender, but it's actually a critically endangered species.
Darwin's frog, found in the forest streams of Argentina and Chile, has quite possibly the weirdest birthing method of any creature. Instead of hanging out in ponds, these little tadpoles help give new meaning to fathers with big fat mouths.
