Inside a Sperm Whale's Mouth

Sperm whales have conical teeth on their long, narrow, lower jaw. The teeth fit neatly into sockets in the upper jaw, which has no teeth. This arrangement is a perfect adaptation for slurping up soft-bodied squids—giant or otherwise. The sperm whale is listed as Vulnerable on the IUCN's Red List of Threatened Species.
