Our family enjoyed swimmimng with the manatees in Crystal River, FL. The manatees love to clean their teeth on the ropes around the boat. We were surrounded by mature and baby manatees - some very playful. There are very strict rules designed to protect the manatees from abuse. These gentle creatures are fascinating to watch and they often want to interact with humans. Our granddaughter (4 at the time) showed no fear and loved watching them playing around the boat.
