Humpback Anglerfish
You have to be a savage sort of fish to actually fish while underwater. The Anglerfish is supremely popular thanks to an appearance in the film Finding Nemo but most ocean dwellers aren’t happy to see it hanging around. The Humpback Anglerfish is a wide jawed creature with a protruding stalk coming out of its forehead that is used to lure in prey.
Blue Ringed Octopus
Don’t get it twisted, the Blue Ringed Octopus doesn’t make this list due to its physically imposing nature. In fact, the octopus is rather small and actually quite pleasant to look at thanks to its wide array of colorful markings. However, the Blue Ringed Octopus is probably the most dangerous creature in the ocean. This octopus has enough venom within its body to kill up to seven adult males. There’s also no antivenom known to man. So, watch out.
