Labeled sperm whale skeleton. Like many cetaceans, the sperm whale has a vestigial pelvis that is not connected to the spine. [citation needed] Like that of other toothed whales, the skull of the sperm whale is asymmetrical so as to aid echolocation. Sound waves that strike the whale from different directions will not be channeled in the same ...

Their skeletal anatomy allows them to be fast swimmers. Most species have a dorsal fin. [28] [43] ... Biosonar by cetaceans Sperm whale skeleton. Richard Lydekker, 1894.
The morphology of the nasal complex is believed to be homologous in all of the echolocating Odontoceti (toothed whales), with the spermaceti organ homologous to the dorsal bursa in the dolphin. [4] The hypertrophied quality of the sperm whale's nose can be interpreted as an adaptation for deep diving unique to Physeteroidea. [5]
• 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 ...
Anatomy of the bottlenose dolphin Features of a sperm whale skeleton Toothed whales have torpedo-shaped bodies with usually inflexible necks, limbs modified into flippers, no outer ears, a large tail fin, and bulbous heads (with the exception of the sperm whale family ).
