"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.

Interesting hour about land mammal that returned to the sea.
And spermaceti oil which was perfect for smokeless lamp lighting for humans which almost led to their extinction.

Anatomist Joy Reidenberg is a fun high-energy woman who I enjoy watching.

The sperm whale is named for the spermaceti oil it produces in its head for ecolocation and buoyancy, For lovers of biology, anatomy and physiology, this is a great film of a very interesting animal. It has a single nostril, holds its breath for about an hour, freedives to enormous depths that force its ribcage to essentially collapse. Those deep sea pressures would kill a human. In an hour, you get to see how it all works, and how a dissection is done on a 60 foot long animal.

Other: Graphic images of animal dissection is the warning at the beginning. Personally, I don't find it bothersome since the animal is already deceased.
