The Manatee -- an endangered species: Take students on a mission to see what's being done to save the manatee, a marine animal sometimes known as a "sea cow" because of its size and diet, which consists mainly of vegetation. We'll journey to points in Florida where the manatee lives and to the Sea World Aquarium in Orlando. There, you'll see how researchers and scientists are studying and protecting the peaceful manatee to ensure its survival. Dolphins -- how they live, learn & communicate: As mammals, humans and dolphins share a number of important biological characteristics. Both species are warm-blooded, have body hair, breathe air, give live birth and nurse their young. But is it possible that we have more in common? Do they like us? Can they reason and solve problems? Just how intelligent are these gentle marine mammals? In this program, join marine scientists from Florida to Hawaii who are trying to answer these and other questions about dolphins by studying how they live, learn and communicate. Spectacular sharks: Sharks have inhabited our oceans for more than 400 million years. Their ability to adapt to their environment over time has classified them as one of the world's most successful species. In this program, we dive into the ocean to take a closer look at these magnificent creatures and examine the qualities and characteristics that have enabled them to survive for millions of years.
