I remember when I was on holiday in Florida a few years ago we went on a tour of the waterways in the south west of the state close to Everglades City (a grand title for a small town) we briefly saw a manatee. It silently came up out of the water, looked at us and then with a gracefulness than defied its size, dived back down into the water it's large flat tale flapping on the water before it disappeared. A few seconds, but I was thrilled to see this shy creature at all. Special animals, and it is good that this little manatee has been saved. You can read more about it here.
