Gulper Eel
This weird looking eel has a mouth that resembles a pelican. This deep-sea monster is very rare and very few facts are known about it. It is known that they live 3,000 meters under the sea and can grow up to a stretch of 6 feet long. One terrifying fact about this creature is that its strange elongated jaw and flexible stomach enable them to swallow their prey that could be of their same size.
