are sperm whales buoyant
The sperm whale (Physeter macrocephalus), or cachalot, is the largest of the toothed whales and the largest toothed predator. It is the only living member of 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.ature males average at 16 metres (52 ft) in length but some may reach 20.5 metres (67 ft), with the head representing up to one-third of the animal's length. The sperm whale feeds primarily on squid. The spermaceti organs may also help adjust the whale's buoyancy. It is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature.The wax therefore solidifies and reduces in volume.t is hypothesized that before the whale dives, cold water enters the organ, and it is likely that the blood vessels constrict, reducing blood flow, and, hence, temperature.

Spermaceti (from Latin sperma meaning semen, and ceti meaning whale) is a waxy substance found in the head cavities of the sperm whale (and, in smaller quantites, in the oils of other whales).Spermaceti is created in the spermaceti organ inside the whale's head.Two theories for the spermaceti organ's biological function suggest it either controls buoyancy, or acts as a focusing apparatus for the whale's sense of echolocation.aw spermaceti is liquid within the head of the sperm whale, and is said to have a smell similar to raw milk. It is composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides. 1 This work has identified another remarkable example of convergence in the biological realm and, with it, raises questions about the validity of the evolutionary paradigm. Sperm Whale Bouyancy. The spermaceti, a large organ in the sperm whale’s head, helps control this behemoth’s buoyancy in the water.The organ contains a vast amount of fatty materials. When the whale is at the surface, the fat exists in liquid form. The fat solidifies when cold water enters the organ and restricts blood flow.rom an evolutionary standpoint, it looks as if an identical buoyancy control mechanism evolved independently in sperm whales and copepods. The very nature of the evolutionary process rests on sequences of improbable, chance events; thus, it should not generate identical outcomes multiple times. The sperm whale (physeter macrocephalus) is a large toothed whale that is part of the cetacean species, which includes all species of whale, dolphin and porpoise.The sperm whale is the largest of the toothed whales and can grow to be as long as 67 ft. They also have the largest brain out of any animal known to exist.perm Whale Facts.

The sperm whale is the largest of the toothed whales and can grow to be as long as 67 ft. Some researchers believe that the spermaceti organ assists the whale with buoyancy by allowing the whale to adjust the fluid balance and consistency within its head; after all the sperm whale is the deepest diving animal in the cetacean family.perm Whale Facts.

Scientists have yet to understand its function, but believe it may help the animal regulate its buoyancy.perm whales' heads are filled with a mysterious substance called spermaceti.
