Three Hearts and Tentacles
Do you know that an Octopus can squeeze through a hole the size of a coin? To be even weirder, this creature has three hearts. The largest one, named Octopus dofleini, can weighs about 15kg. Hapalochlaena has enough venom in one bite to kill an adult human. They have two tentacles for walking and six remain free. This makes them look like an armed vehicle.
