We all wonder what alien life might look like, but there are some strange creatures swimming in our oceans that are more bizarre than anything Hollywood has imagined. About 71 percent of the surface of the Earth is covered in water and we are still only beginning to discover the incredible biodiversity and unusual denizens of the oceans. Ocean life and sea animals are full of surprises, and there are all kinds of cool fish (and a few scary ones) living in the ocean.

What fascinating fish facts should you know about the many creatures of the ocean depths? Did you know that until 2013, no one had ever recorded a video of a giant squid alive? The coelacanth was thought to be extinct for millions of years until one was caught alive in 1938. There are also an array of alien-like jellyfish and terrifying deep-sea monsters that look like something out of a horror movie.

So what is the weirdest, wildest ocean creature alive? Believe it or not, all the ocean animals and fish below are 100% real. Vote up the most interesting and maybe slightly scary facts about ocean life below!
