According to Russ Sittloh, 78, he called the creature Normandy Nessie because he lives on the Normandy Road. Sittloh has seen this Madeira Beach Monster, as it's been referred to, six times over the last few months. A biologist from Florida Fish and Wildwife reviewed the video that Sittloh took and said that the "monster" might be a manatee. Sittloh said this creature might be an anaconda but it's tail is nothing like that of a giant snake. He said that whatever it is, this thing could be dangerous.

Well, below are pictures of a manatee:

I think, if this mammals could be what Sittloh had seen, then these creatures are not monsters. They are friendly in nature and are mainly herbivores. Manatees spend most of their time grazing in shallow waters and at depths of 1-2 metres (3-7 ft). Much of the knowledge about manatees is based upon research done in Florida. So that monster mentioned above might actually be a manatee.
