One of the most amazing habitats on earth is found in warm, clear, shallow waters of tropical oceans worldwide. Tiny cup-shaped animals, called polyps, live in colonies, and when they die, their skeletons form a hard, stony, branching structure made of limestone.
In our first episode we examine coral -- the growing, living, incredible, under-the-sea structures that provide shelter and food for many marine animals.
