Belcher’s Sea Snake
These sea snakes are very dangerous. They are quite visible and several movies and TV specials have used them. It would not be a big surprise if you have seen one yourself. You can easily recognize one by the stripes on its body. They are usually shy and avoid contact with people as much as possible. However, it may not work in your favor if you threaten them. They will bite back if they sense trouble or fear for their lives.
