• Newborn sperm whales are between 3.7 to 4.3 meters (12 to 14 ft) in length. [1] • Sperm whales exhibit a large amount of sexual dimorphism with their size and proportions, with males generally being much larger than females. Female sperm whales are sexually mature at 8 to 9 meters (26 to 30 ft) in length, and physically mature at about 10 ...
• 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 ...
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.

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.
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.

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 ...
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.
The whale was measured at about 44 feet (13 meters) long, roughly the size of a large school bus. It weighs as much as 70,000 pounds (31,700 kilograms), officials said.
