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.

Livyatan is an extinct genus of sperm whale containing one species: L. The genus name was inspired by the biblical sea monster Leviathan , and the species name by Herman Melville , the author of the famous book Moby-Dick about an albino bull sperm whale. It was found in the Pisco Formation of Peru and lived during the Tortonian stage of the Miocene epoch , about 9. It was a member of a group of hyper-predatory macroraptorial sperm whales or "raptorial sperm whales" and was likely an apex predator , preying on whales, seals, and so forth. Characteristic of raptorial sperm whales, Livyatan had functional, enamel -coated teeth on the upper and lower jaws, as well as several adaptations for hunting large prey.
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 mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales orcas.
