The Indo-Pacific mimic octopus is a master of disguise. It can replicate the colours and patterns of over fifteen different species, allowing it to elude predators and ambush unsuspecting prey.
South America's most formidable animal, the electric eel, can produce up to 600 volts of electricity, which it uses to identify prey in murky waters, much like a radar.
It is a dangerous predator because of its explosive claw, which it can use to snap shut at nearly 60 mph and produce a shockwave-producing cavitation bubble.
The incredible eyesight and quick reflexes of the mantis shrimp allow them to strike quickly underwater and produce shockwaves and bubbles that can reach temperatures of over 4,700 degrees Celsius.
The immortal jellyfish, despite being unable to revert to its juvenile polyp state, can potentially become biologically immortal, potentially continuing eternally.
Originating in the rainforests of Central and South America, the Hercules beetle is incredibly strong. It can move objects that weigh more than 850 times its own weight, mostly because of its evolved horn-like structure.
The cheetah is the fastest terrestrial mammal in Africa, with acceleration and agility that may approach 60 mph in a matter of seconds.
