Scientists believe that sperm whales and giant squid are natural enemies.
Whalers once believed that the oily fluid was sperm, but scientists still do not understand the function of spermaceti. The spermaceti organ is unique to sperm whales. Sperm whaling was a … Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree....
Spermaceti was used chiefly in ointments, cosmetic creams, fine wax candles, pomades, and textile finishing; later it was used for industrial lubricants.

It is thickset and has small paddlelike flippers and a series of rounded humps on its back. One common theory is that the fluidâwhich hardens to wax when coldâhelps the whale alter its buoyancy so it can dive deep and rise again. The principal function of the spermaceti organ and its associated structures (the junk, air sacs and passages, and the museau de singe clapper system at the front of the organ) (Fig.
The sperm whale produces a substance called ambergris or grey amber, which is a waste product of its digestive system. Beachcombers look out for ambergris as flotsam. Males migrate to higher latitudes, alone or in groups, and head back towards the equator to breed. Hide Dive …
Scientists have yet to understand its function, but believe it may help the animal regulate its buoyancy.Sperm whales are easily recognized by their massive heads and prominent rounded foreheads.They have the largest brain of any creature known to have lived on Earth.
Light only penetrates a limited distance underwater so it uses echolocation to find its way around and hunt for squid.
Possesses. Spermaceti (sperm oil), from which the whale derives its name, was a prime target of the whaling industry, and was sought after for use in oil lamps, lubricants, and candles. Get kids back-to-school ready with Expedition: Learn! A mythical albino sperm whale was immortalized in Herman Melville's Despite large population drops due to whaling, sperm whales are still fairly numerous.
Driven by their tale fluke, approximately 16 feet from tip to tip, they can cruise the oceans at around 23 miles per hour.These popular leviathans are vocal and emit a series of âclangsâ that may be used for communication or for echolocation. While no actual battles have ever been observed, sperm whales sometimes carry round scars believed to have come from …
Animals that use echolocation emit sounds that travel underwater until they encounter objects, then bounce back to their sendersârevealing the location, size, and shape of their target.Sperm whales were mainstays of whaling's 18th and 19th century heyday.
Ambergris, a solid waxy waste product sometimes present in its digestive system, is still highly valued as a fixative in perfumes, among other uses.

The sperm whale’s head is large because it contains a huge cavity called the spermaceti organ which is thought to help the whale control buoyancy and dive to deep depths.
2) is to form, and focus, the sperm whale's click, making an extremely powerful communication and echolocation system (Cranford, 1999; Møhl et al., 2000).

A sperm whale will dive 2-3km in search of prey and hold its breath for up to two hours, although 45 minutes is the average dive time.
Their heads also hold large quantities of a substance called spermaceti.
