Sperm whale and bottlenose whale. The sperm whale (Physeter macrocephalus) is the largest species of toothed whale, with adult bulls (males) growing to be about 15–18 m (49–59 ft) long, and weighing about 45–70 metric tons (44–69 long tons; 50–77 short tons).
However, the amount of fish taken is very little compared to what the sperm whale needs per day. Video footage has been captured of a large male sperm whale "bouncing" a long line, to gain the fish. [164] Sperm whales are believed to prey on the megamouth shark, a rare and large deep-sea species discovered in the 1970s. [165]
Zygophyseter varolai is an extinct sperm whale that lived during the Tortonian age of the Late Miocene 11.2 to 7.6 million years ago. It is known from a single specimen from the Pietra Leccese Formation in Italy.
Physeter is a genus of toothed whales.There is only one living species in this genus: the sperm whale (Physeter macrocephalus). [2] Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus (5.3–2.6 mya) from the Pliocene of France, [3] and Physeter vetus (2.6 mya – 12 ka) from the Quaternary of the U.S. state of Georgia.

The term "Great Whales" covers those currently regulated by the International Whaling Commission: [8] the Odontoceti family Physeteridae (sperm whales); and the Mysticeti families Balaenidae (right and bowhead whales), Eschrichtiidae (grey whales), and some of the Balaenopteridae (Minke, Bryde's, Sei, Blue and Fin; not Eden's and Omura's whales).
Macroraptorial sperm whales occupied the same niche as killer whales (Orcinus orca). Using their large and deeply rooted teeth, wide-opening jaws, and great size, they likely fed on a variety of sea life, including fish, cephalopods, seals, and small whales and dolphins, occupying a niche similar to the modern day killer whale (Orcinus orca).
