3. Gulper Eel
The Gulper is one of the largest animals in the world and is able to reach a length of over 60 feet. In fact, there is little information known about this mysterious deep sea fish because none of it is seen alive in the world today.
Most of the information we have has been deduced from the dead skeleton washed up the shore or pulled to the ground by fishermen’s nets. These animals are known to be carnivores and can therefore eat anything that comes in their way. Some unconfirmed reports suggest that these deep sea fish have at certain times invaded small boats and pulled out people for prey.
