Description:How long do sperm whales live? Its surrounding wall, known as the case, is extremely tough and fibrous. They were once thought to be a way by which individuals identified themselves, but individuals have been observed producing multiple codas, and the same codas are used by multiple individuals. The sperm whale's flukes tail lobes are triangular and very thick. In these situations it appears that the giant squid latches onto the sperm whales head with its tentacles in an attempt to avoid being eaten. Davis and his colleagues searched for whales in their research vessel during the day by listening for the clicks they made with hydrophones, or underwater microphones. It is thought that the nostrils of the land-based ancestor of the sperm whale migrated through evolution to their current functions, the left nostril becoming the blowhole and the right nostril becoming the phonic lips.
