Kogia pusilla is an extinct species of sperm whale from the Middle Pliocene of Italy. related to the modern-day dwarf sperm whale (K. sima) and pygmy sperm whale (K. breviceps). It is known from a single skull discovered in 1877, and was considered a species of beaked whale until 1997. The skull shares many characteristics with other sperm ...
Male sperm whales are sexually mature at 11 to 12 meters (36 to 39 ft), and physically mature at about 15 to 16 meters (49 to 52 ft) in length, on average. Larger-than-average females have been generally recorded around 12 to 13 meters (39 to 43 ft), and larger-than-average males are usually stated to reach a maximum of about 18 to 19 meters ...
Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

In 1853, one sperm whale was reported at 62 feet (19 m) in length, with a head measuring 20 feet (6.1 m). [46] Large lower jawbones are held in the British Natural History Museum and the Oxford University Museum of Natural History, measuring 5 metres (16 ft) and 4.7 metres (15 ft), respectively. [44]
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.

Sperm whales, which can reach about 60 feet (18 meters) long, have the largest brain of any animal. They are deep divers, feeding on giant squid and other prey.
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
The bank is, on average, 100 to 120 feet (30 to 37 m) below the surface, while surrounding waters to the west are over 300 feet (91 m) deep and to the northeast as deep as 600 feet (180 m). The underwater cliff-edge of Stellwagen Bank runs parallel to the coastline and is referred to as the " shelf break."
