Black Mamba
This animal’s name is derived from the black lining of its mouth. You’ve probably heard of the terrifying Black Mamba before! Their speed, in our opinion, is what makes them truly terrifying. After all, not many venomous snakes can travel at speeds of up to 12 and a half mph.
Giant Pacific Octopus
With a name like that, it’s only natural to assume this creature will be enormous. You’ve probably figured out where it’s kept. The Giant Pacific Octopus can reach a length of 16 feet and a weight of 110 pounds. When hunting for food, it can also adapt to its surroundings and hide undetected.
