Explore the blue coastal waters of southern Florida with Brian Skerry as he discovers the underwater world of the most lovable marine mammal - the manatee. Children will discover that this roly-poly gentle giant is actually quite fun to observe.

With their playful natures and clumsy qualities, manatees roll around when playing and even squeal with delight when they are excited.

But their world is in danger - pollution is putting their freshwater habitats in peril and the over-population of local rivers and streams is leading to more and more accidents with humans.

Learn all about manatees, and why we should do our best to protect their habitats and way of life.
