Digging around inside nature’s giants
A sperm whale’s penis has no bones. This allows its flexible member to penetrate a female sperm whale from any number of directions; a necessity when two multi-ton animals are trying to line up tab A with slot B in an unsteady ocean environment.
This and other interesting facts about sperm whales are the subject of the first episode of the documentary series Inside Nature’s Giants, which premiers in the U.S. on January 18th. Each of the series’ four episodes centers around the dissection of a large animal, which is used as a starting point to explore the animal’s biology. (A clever device, which I also used in this Scientific American video about jumbo squid.)
