I was curious about the reality of many claims over the centuries of sea serpents or large ocean monsters so I thought I'd research this subject myself. There were many amazing stories such as the giant whale which attacked a ship in the nineteenth century. This event was the reason Herman Melville wrote the book "Moby Dick". There are many records of giant fish and serpents in the water. The question is which of these have some basis in reality. History records many types of monsters of the deep. The question is how many are real or just mythology. We also now have satellite pictures which show some incredible images of possible water monsters on our Earth. In this book I tried to do some comprehensive research on the giants of the deep and I hope you find this interesting.
