Normandy Nessie, the Bay area's version of the Loch Ness Sea Monster?Russ Sittloh, who first video taped a mysterious black 20-foot long creature in the canal behind his Madeira Beach home more than a year ago, believes it could be Normandy Nessie.Sittloh named the creature Normandy, after the road he lives on.Photo Gallery: Sittloh's images of Normandy NessieExperts say what Sittloh and others have seen could be anything from a manatee to an anaconda."Most of the time when people see this stuff, they don't get to see it for any real length of time and it's so far away, it's really hard to make out," said Vernon Yates of Wildlife Rehab and Rescue.Sittloh now believes Normandy is an anaconda and he believes he's seen more than one swimming in the water behind his home."People don't want to believe that. They don't want it to be true, because of the tourist stuff," Sittloh said.Yates says he's captured several dozen anacondas in the Bay area over the years with the largest measuring about 15 feet long. But Yates says anacondas will usually stay away from salt water."Does the possibility exist it could be an anaconda? Very much so. Probability, not really, because again, he would stay out of the salt water," Yates told 10 News./>
