Originally broadcast on PBS in 2012 as part of the series Inside nature's giants.
"Most wildlife documentaries focus on animal behavior, but Inside Nature's Giants goes inside the largest animals on the planet to explore their anatomy, reveal their intricate inner workings and uncover their evolutionary secrets. In this episode, veterinary scientist Mark Evans and comparative anatomist Joy Reidenberg battle through the night against a rising tide to explore the mysteries of the largest predator on Earth--the Sperm Whale. Despite their enormous size, we know very little about Sperm Whales because their lives are normally hidden deep beneath the waves. Can this award-winning team successfully dissect the answer to how these whales can survive hour-long dives of over a thousand meters with just one gulp of air, in conditions that would freeze our blood and crush our bones?"--Container.
