Oceans are mysterious places. With 95 percent of the world’s oceans still unexplored, there are still so many things we don’t know, which, you have to admit, makes oceans not only mysterious, but also pretty scary. The truth is that oceans are full of strange creatures you may not even have heard of and who look downright terrifying. Let’s take marine iguanas, for example. These creatures look like some sort of a weird mix between Godzilla and crocodiles, only they can hold their breath underwater for long periods of time. These images were captured Cabo Marshall in the Galapagos Islands.
