Other localities of similar age on the South African west coast have also yielded many additional species of balaenopterids and sperm whales as well as ten species of beaked whales. Large sperm whale teeth of up to around ~20 cm (8 in) in length are common in Hondeklip Bay, indicating a high presence of large sperm whales like Livyatan in the ...
Livyatan probably targeted medium-sized whales ranging in size from 7–10 m (23–33 ft). Macroraptorials probably competed with the extinct giant shark megalodon for the same food sources. [7] [10] [11] [12] In sperm whales, the supracranial basin holds the spermaceti organ, a series of oil and wax reservoirs which aids in echolocation.
The lumbar vertebrae were elongated and may have supported large multifidus and longissimus muscles in the back, likely larger than the modern sperm whale, and so it probably swam faster than the modern sperm whale; [1] the modern sperm whale typically travels horizontally at 4 kilometers per hour (2.5 mph), comparable to other large open-ocean ...
The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.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.
• Physical maturity for female sperm whales is around 10.6 to 11 meters (35 to 36 ft) on average, whilst for male sperm whales, it is around 15 to 16 meters (49 to 52 ft) in length. Above-average females have been recorded up around 12 to 13 meters (39 to 43 ft), and the maximum size usually stated for males is males around 18 to 19 meters ...
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).
The various species of whales inhabiting Earth's oceans employ different types of vocalizations to communicate. Sperm whales, the largest of the toothed whales, communicate using bursts of ...
I. Sperm whale (Physeter macrocephalus), the most important prey of Nantucket whaling fleet, which operated principally in the Pacific Ocean and Indian Ocean. The notorious fictional white whale Moby Dick in the novel is of this species, and is based on the real-life sperm whale Mocha Dick in the South Pacific in the 1840s. For dramatic effect ...
