Looks like Rocks...these are all Manatees.....           We swam with the Manatees today. An UNBELIEVABLE experience. We were lucky enough to have a special day. Even the guides were amazed at how many there were. One of the guides said there were more than two hundred in a very small area.
Swimming with them was amazing...they are 12-18' long and several thousand pounds, but they are incredibly gentle. They seem to like human contact and come right up to you and right in your face to check you out. Hopefully some underwater pix we took will come out.
Well worth seeing and doing if you ever get a chance.
