1. A Sea Snake?
Again, sea monsters are commonly found in the deepest and darkest parts of the ocean, such as the frilled shark, which avoids attention of divers by staying at the bottom of the ocean. What’s scarier than its big mouth and odd shape? Its 300 sharp teeth.
2. The Goblin Shark
Another creature from the deeper part of the ocean, goblin sharks are slimy, disgusting and utterly scary sea creatures.
