Aquatic ecologist Zeb Hogan gets up close and personal with bizarre giants of the water, specimens equally enormous in proportion and odd in appearance. Among other adventures, he investigates flying fish from Asia that are invading America's waterways, and searches for one of North America's toothiest and most misunderstood monster fish, the alligator gar. Some of the species Hogan encounters have survived for centuries but now face the threat of extinction, and he presents groundbreaking research undertaken to protect them.
