Manatees are docile, large sea mammals who are eaten in some parts of the world, feared in others, and adored in still others. But human encroachment, disease, environmental hazards, and being hunted, among many other issues, are causing their numbers to decline. In Manatee Scientists, readers meet three scientists working very hard in three different parts of the world to save the manatee.
