Update 2:

sorry! i learn in english of this subject!!!!! ~~~ i am so sorry!

The Sperm Whale is the largest toothed whale in the world. They dive the deepest and longest of all cetaceans, and are probably rivaled only by the two bottlenose whales of the beaked whale family, the Bottlenose Whale. Sperm whales are probably the most abundant of the large whales, except for the period of whaling when they used to be considered the number one target. Herman Malvill's classic Moby Dick, in which the heroic Moby Dick is a sperm whale, is one of them. The species name macrocephalus is derived from the Greek word for "big head". There is also a species name for sperm whales, catodon, and this has led to a lengthy debate in the past, with macrocephalus seeming to be the predominant name at present.

000kg Maximum length and weight: male - 18.3m, 57

000kg; female - 11m, 24

Lifespan: at least 60-70kg. 000kg Lifespan: at least 60-70 years Physical characteristics The sperm whale's head is extremely large and disproportionate in relation to its body, especially in adult males, reaching up to one-third of its full length, and is roughly square in appearance. The lower jaw is narrow and bar-like, shorter than the upper jaw, and is not easily visible when viewed from the side. The skin surface of the middle and rear of the body usually has many horizontal folds, unlike the smooth, firm skin of other cetaceans, which is usually less pronounced in obese individuals. The blowhole is located at the front of the head and to the left because the skull of the sperm whale develops with a very severe tilt to the left. The dorsum has a low bulge relative to the dorsal fin, followed by a series of smaller protrusions that extend all the way to the caudal fin, with a thick caudal peduncle. The pectoral fin is short and broad with a *** tip, and the caudal fin is triangular with straight edges. The sexes of sperm whales vary greatly in size, with adult males usually one-third longer than females and weighing up to twice as much as females. The lower jaw has twenty to twenty-six pairs of large, conical teeth, while the upper jaw has small teeth that are buried in the gums or are only alveolar. Sperm whales are dark gray in appearance, but may appear tan in bright sunlight. The upper lip and lower jaw are white near the tongue, and there are usually irregular white *** patches on the belly and flanks. Distribution Sperm whales are widely distributed in the world's ice-free seas, from the equator to the poles, where they can be found, with the deeper, more productive waters being the most productive, and where whalers used to call the areas where sperm whales frequented "ground. The distribution of adult males and females is markedly different, with females usually found in waters deeper than 1,000 meters and within 40 degrees latitude, but in the North Pacific they can reach 50 degrees latitude; males follow their mothers in the tropics as juveniles, and when they grow up, they will leave the group and gradually move to higher latitudes. The larger and older the male whales, the higher the latitude of their distribution range, and even closer to the polar ice floes. Females and immature sperm whales usually stay in groups that are at least 10 years across an area of 1,000 kilometers, whereas adult males move over a much wider area. Habits Surface Behavior Because of their long dive times, sperm whales are not often seen at the surface, but their distinctive shape and jet make them difficult to confuse with other large cetaceans. Between dives sperm whales will float or swim slowly at the surface, resembling giant driftwood in appearance; the jet, which is tilted about 45 degrees to the left, is low and bushy. There is often a leap to hit the waves or a whales tail to hit the waves. Diving When sperm whales dive, the most obvious sign is the tail lift (fluking), in which they raise their tail fin high in the air and then descend vertically. Sperm whales have been known to dive as deep as 3

195 meters below the surface, with a closed-breath time of 138 minutes, but normal dives are much less than that, typically reaching depths of 400 meters for about 35 minutes, with larger males able to dive even deeper and longer. Social Structure Long-term stable groups of females form the core of sperm whale society, with small groups of up to 12 adult females accompanied by their female and young male offspring. Males leave their birth families at around 4 to 6 years of age and become independent after 21 years of age at the latest, and young males often form so-called bachelor schools, in which the participants are mostly of similar size and age, but the bonds between the individuals are not as strong as in the female groups described above, and become looser as they age. Elderly males of 12 to 17 meters in length tend to roam the ocean alone and are rarely seen interacting for more than a day. Whole pods of sperm whales sometimes strand on beaches. Social Behavior Because adult males often have severe head injuries, sometimes with broken teeth or even broken jaws, scientists believe that individuals may engage in intense fighting behavior. Different groups of females seem to communicate with each other through sound when they encounter each other. Fleeing and Fighting Back Sperm whales are often portrayed in novels and movies as strong, powerful animals that attack ships, but in fact, when they are in danger, they most often choose to flee. When a sperm whale realizes that it is in danger, it will poke its head out of the water and slowly rotate its body to get a better view of its surroundings. Once it recognizes that there is a danger, such as a killer whale, it will quickly accelerate out of the area or dive deeper, with the rest of the group following if just one of the whales escapes. Sperm whales swim at an average speed of 2 to 3 knots (1 knot is equivalent to 1.852 kilometers per hour), and may reach speeds of up to 7 knots when escaping, with records of chased sperm whales running at 12 knots during the whaling period. Sometimes the whales choose to fight back, and there are many documented accounts of whaling ships being attacked and even destroyed by sperm whales. Their massive hammer-like heads and powerful tails are so destructive that ships are often destroyed by their walls or tipped over by their tails, and whaling boats have been known to be bitten off by angry whales in the past.

The sperm whale, the Sperm whale. Sperm whales are huge, toothed whales with a head that is about 40% of their body length (one-third of their total length)

Shaped like a box, they have a narrow jaw with 40 to 50 conical teeth up to 25 centimeters in length

but no teeth in the upper jaw, and only one blowhole in the head, which emits a column of mist at a 45-degree angle to the left. They can weigh up to 35 tons and are 18 meters long, but there is a big difference between male and female sperm whales in terms of length and weight. Adult males average 35-45 tons

Females weigh only 13-14 tons. The heaviest male sperm whale recorded was 57 tons

The heaviest female sperm whale was 24 tons. Lifespan is about 60-70 years. Sperm whales also have a prodigious appetite, eating up to 200 kilograms of food in a single meal. Their favorite food is squid and octopus

In order to prey on the king squid and octopus in the deep sea, sperm whales can be called a real diving champion, in the sea at a depth of 3,000 meters, out of reach, cold and bone-chilling seawater, the pressure is equivalent to the atmospheric pressure of 300 times the pressure of more than 300 kilograms per square centimeter, they can also be dived down to dive underwater, they are able to dive down to 150 meters per minute vertical speed, the speed of the water is not enough. After submerging, they can rise vertically at a speed of 150 meters per minute; several sperm whales have been recorded closing their mouths in the water for 138 minutes before coming to the surface. Why do sperm whales have such strong diving instincts? It's because they can adjust their body density to the pressure of the water around them, and they can change their body density, mainly by exchanging cold seawater with warm blood, a very complex system that changes the temperature and density of the whale's wax oils, which helps them to dive or surface effortlessly. Ambergris, on the other hand, is a valuable animal spice

It is only produced and found in the digestive tract of male sperm whales, and is mostly secreted after feeding on king squid. Li Shizhen's "Compendium of Materia Medica" only with the collection of "dragon's saliva", ambergris may be too precious, except for the princes and nobles, very difficult to encounter, the ordinary people since it is not easy to know, but also non-traditional Chinese medicine. And Gong Zhen's "Western Panchu Zhi" records slip mountain, Zufar, Tianfang three countries "out of ambergris incense, fishermen slip in the pick, like dip asphalt, smell is not fragrant, burning fishy gas. The high price of silver to easy". Fei Xin's "Crews Shengli" also recorded ambergris islet "alone in the south of the sea, the waves hit the clouds, every spring, a group of dragons gathered, on the play, and the taste of saliva ...... its dragon saliva at first like fat glue, black and yellow, quite fishy gas, long time achievement of the soil mud." Ma Huan's "Ying Ya wins" recorded *** people with ambergris the reality.
