So what is the rarest animal on the planet? Actually, that is a surprisingly difficult question to answer. Accurately determining the number of animals in a particular species is not a walk in the park since most don’t really participate in censuses. Some animals are so rare that they might already be extinct and we just don’t know it yet. Others are extinct in the wild and can only be found in captivity. But from what we know, the four creatures featured below are as rare as prime rib.
Pygmy Three-toed Sloth
The sloth is already one of the most adorable creatures on Earth, but to be honest, it’s not really much of a survivor. You put it in any kind of dangerous situation and it is likely to perform poorly. Therefore, it shouldn’t be that surprising to find out that the pygmy three-toed sloth is critically endangered.
