An Amateur Hypothesis on Sperm Whale Buoyancy 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.

What Do Sperm Whales Eat? When the sperm whale rises to the surface markings can often be found on and around the sperm whales head which appear to be caused from battles with the giant squid they are trying to consume. In comparison to the colossal squid these marine mammals eat adult sperm whales can grow to lengths in excess of 50 ft. long and weight more than 45 tons with the large sperm whales growing to lengths of up to 67 ft. long.

- The sperm whale has a lower encephalization quotient than many other whale and dolphin species, lower than that of non-human anthropoid apes, and much lower than humans'. The sperm whale's cerebrum is the largest in all mammalia, both in absolute and relative terms. The olfactory system is reduced, suggesting that the sperm whale has a poor sense of taste and smell. By contrast, the auditory system is enlarged. The pyramidal tract is poorly developed, reflecting the reduction of its limbs. Biological systems

- Plunging to 2,250 metres (7,382 ft), it is the second deepest diving mammal, following only the Cuvier's beaked whale. The sperm whale's clicking vocalization, a form of echolocation and communication, may be as loud as 230 decibels (re 1 µPa at 1 m) underwater. It has the largest brain of any animal on Earth, more than five times heavier than a human's. Sperm whales can live for more than 60 years. The sperm whale can be found anywhere in the open ocean. Females and young males live together in groups while mature males live solitary lives outside of the mating season.

- Thirty teeth of the sperm whale can be used for ivory. Each of these teeth (up to 20 cm (8 in) and 7.6 cm (3 in) across), are hollow for the first half of their length. Like walrus ivory, sperm whale ivory has two distinct layers. However, sperm whale ivory contains a much thicker inner layer.he sperm whale's lower jaw is very narrow and underslung. The sperm whale has 18 to 26 teeth on each side of its lower jaw which fit into sockets in the upper jaw. The teeth are cone-shaped and weigh up to 1 kilogram (2.2 lb) each.

Sperm Whale Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of orcas.

Sperm Whale Living in a pod allows females to better protect their calves from orca attacks. Once sperm whales reach maturity, there are no predators except man capable of killing them, and their lifespan in the wild is approximately 70 years. Calves are born every three to six years and can take 10 years to mature.

Whale Although whales are widespread, most species prefer the colder waters of the Northern and Southern Hemispheres, and migrate to the equator to give birth. Odontocetes feed largely on fish and squid. A few, like the sperm whale, feed on large invertebrates, such as giant squid.Grey whales are specialized for feeding on bottom-dwelling molluscs. Male whales typically mate with multiple females every year, but females only mate every two to three years.he whale eye is relatively small for its size, yet they do retain a good degree of eyesight. As well as this, the eyes of a whale are placed on the sides of its head, so their vision consists of two fields, rather than a binocular view like humans have.

What is Cold Water? Seals, whales, and other warm-blooded aquatic mammals have a lot of this insulating fat - called blubber - which enables them to keep warm while swimming in cold oceans. Because fat provides insulation from the cold, it can delay incapacitation and hypothermia and also improve physical stamina in the water.

Facts about whales The sperm whale’s huge head, which is up to a third of its overall body length, houses the heaviest brain in the animal kingdom - up to 9kg. The head also consists of a cavity large enough to park a car inside that contains a yellowish wax called spermaceti that was much sought after by whalers.

Whale So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on.

Nelson Institute of Marine Research In general, the larger the animal, the slower the heart beat. The sperm whale is the largest of the toothed whales. Adult males measure up to 18m (60 feet) in length. The usual heart rate of large whales is from 10 to 30 beats per minute.

- Humpback whales do not have periods. Lucky things. But like all mammals they have estrus cycles, i.e they ovulate and have even been found to synchronize the timing of their estrus cycles. But, pregnancy lasts nearly a year. Females reach sexual maturity at 6-8 years of age. The typical pattern is: get pregnant in the Caribbean one winter, travel north for the summer and back down the next and have the baby.

One of the most important innovations in voting technology came about in Australia. In 1858, an election was held in the state of Victoria using standardized paper ballots that listed all candidates for office.

- Whales fall into two groups: baleen and toothed, like this sperm whale. Despite impressive teeth, sperm whales use suction to pull in prey. They have been known to dive over 6,500 feet and remain under water for more than an hour in pursuit of giant squid.

How the sperm whale can hold its breath for 90 minutes Biologists have unravelled why deep diving mammals such as sperm whales can hold their breath for over an hour when diving for food – they have electrically charged proteins in their blood. Sperm whales make some of the longest dives achieved by mammals, with some lasting up to 90 minutes Photo: AP.

Whale 'sense of smell' revealed Further studies though backed up the discovery that bowhead whales do indeed smell. Bowhead whales have a relatively large, developed olfactory bulb that appears similar in structure to that in other animals with a developed sense of smell. The researchers also found that bowheads have mostly functional olfactory receptor proteins, which toothed whales do not.
