16. Frilled Sharks
You thought we were done with underwater spooky creatures? Here is the frilled shark, a deep water creature that doesn’t know a lot – meaning that this is the most primitive shark species on Earth. With a body structure that reminds us of snakes, a lizard head and a giant mouth, this is definitely something you don’t want to cross paths with.
What you see inside its mouth is 300 extremely sharp teeth that point inwards so its prey never – ever – escapes once it’s caught.
