Sperm whales are named after the spermaceti oil wax that they produce in the spermaceti organ located in their head. It is because of this oil that man hunted the sperm whales, going after the prized spermaceti oil that was used to make smokeless candles during the 19 th century. Sperm whales are one of the deepest diving whales, they usually dive hundreds of meters to find their food but have been recorded at depths of over m which is phenomenal. Sperm whales eat prey found on or near the ocean bottom, squid is their main diet but they also eat sharks and various bony fish.

The Giant Sperm Whale
It is the only living member of the genus Physeter and one of three extant species in the sperm whale family , along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. The females cooperate to protect and nurse their young. Females give birth every four to 20 years, and care for the calves for more than a decade.
A gigantic pearly white, once belonging to a prehistoric sperm whale, has been unearthed in Melbourne, Australia. Melbourne local and fossil enthusiast Murray Orr discovered the centimetre tooth while walking along the beach at Beaumaris Bay. Even a single fossil tooth like this can offer important clues for researchers who are decoding the past. Fitzgerald adds that we can expect to see more exciting finds coming from Beaumaris Bay, as the site's rocks are of unique makeup and age. We suspect that parting with his amazing find was a little tough for Orr, but by donating it to the museum he has ensured it will be enjoyed by curious visitors for generations to come.
