The Manatees (Trichechus manatus latirostrus) shown here are from Three Sisters Spring, Crystal River, Florida. The warm water springs provide habitats for the manatee populations that migrate here each winter. The shots in blue water were taken inside the springs, the low viz shots in green water in the canal outside the springs.
Manatees are mammals that belong to the order of Sirenea. Which is derived from mermaids. It seems that Columbus when he spotted manatees along the coastline of America believed that what he saw were the legendary mermaids.
One says that the manatee is closely related to the elephant, with which they share a common ancestor. There are definitely some striking resemblances: the manatee is a vegetarian equipped with flexible muscular lips for ripping of vegetation like the elephants trunk. It has molar teeth that move forward in the mouth. A grey skin covered with sparse hairs, finger nails like the elephant toenails and a spherical shaped heart. See album: Manatees
