虎鲸 外型特征
Killer whale's body is very sturdy, the dolphins Division (class delphinidae) in the largest size of species. Head cylindrical cone, there is no prominent beak. Big and tall dorsal fin in the back of the center of a high degree of variability in the shape of the female whales, killer whales, the dorsal fin with a minor was sickle-shaped, while the adult male whales, such as thorns like the most upright, height of about 1 to 1.8 meters. Pectoral fins large, broad, roughly circular, with most of the dolphin families this typical sickle-shaped dorsal fin members are different. Upper and lower jaws have 10-14 pairs of large, sharp teeth. Killer whale's body color pattern of black and white mainly two distinct color contrast composition of the white area in the ventral body back from the lower jaw extends to the anus, between the pectoral fins in all black has become narrow, to produce the rear navel differences, the ventral tail fin is also white. Back and side of the body are black, but in the reproductive crack flanks at the nearby white patches behind the eyes are also obvious oblique oval spots. In the dorsal fin to the rear of a gray and white saddle markings (saddle).

Distribution
Killer whales are widely distributed in waters around the world, for the water temperature, depth and other factors did not seem obvious limitations. They have quite a high latitude habitat of high density, especially in the waters of sufficient prey. The movement of their universal and tracking on or increase predation rates on prey, usually fish spawning season and seal in the production period. In summer, most of the killer whales in the Atlantic Ocean are ice edge habitats in the watercourses or ice to be whales, penguins, seals for food. They will migrate to where moves far, has not yet been finalized. Part of the killer whales in Antarctic waters will remain throughout the year, and killer whales in the Arctic are rarely close to the ice. According to Washington state and British Columbia's killer whales, the researchers point out, where there was _set_tlement type (resident) and passage type (transient) killer whales are two types of local year-round can be found in the two groups. Some individuals have a very large range of activities, from all over the photo identification was found that the range of activities that some killer whales have been from Alaska to the south of California.

Habits
Killer whale attack from time to time there will be awarded by the waves, floating glimpse of such acts, or tail or pectoral fins to slap the water. Killer whale swimming up the fastest speed of 55 kilometers per hour, about 17 minutes to breath. When cool the surrounding air, it is usually low and they can see the jet was dendritic. Their response to various ships, full of curiosity and indifference or neglect are likely. Mass stranding occasionally, groups sometimes trapped in tide pools or bay. In the Arctic and Antarctic waters, because the ice produced by the wind and fast in terms of killer whales is a lot of trouble, sometimes forcing them to stay in the water so a small open waters for a long time.

Feeding habits
Killer whale food variety, from the clustering of small fish, squid, has been to large baleen whales and sperm whales (sperm whale) are likely to become their prey; other fins such as seals and other animals, sea turtles, sea otters, manatees, dugongs ( dugong), sharks, rays, etc., and even deer and elk, they seem to swim across the waterway to take advantage of opportunistic predator. The group seems to have their own types of food preferences, such as certain ethnic groups mainly in salmon, tuna, herring and other fish as main food, some of the group will visit the landing of fins category to find prey, or follow the migration of whales, caribou like the scene to track wolves. Killer whale attack a clear need for cooperation and subdue large prey, but they also force the fish concentrated into a big ball, then turns drill into feeding. Killer whales also eat fish hook longline fishing vessels, or eat the fishermen under the discarded trash and so on. They seem to be _select_ive Yaosi whale tongue. The prey of killer whales may be deeply affected by the fear, occurs when the killer whale fins class will flee to land or ice, whales and dolphins will swim into shallow waters or hide in the cracks between ice floes.

It's physically strong and powerful, a large, was spindle, smooth surface, the skin beneath a thick layer of fat used to preserve body heat. Body length is approximately 600-1000 cm, weight 5000-8000 kg. Body color black and white, back is painted black, but in the back of a saddle-shaped fins gray spot, behind the eyes have a spindle of white, mostly white ventral color. Head more rounded, not prominent snout, the right nostril in the head, a switch freely in the valve, when the float to the surface when to open the valve breathing, a foam-like aerosol spray, face the sea The cold air becomes a water column. Forelimb into a pair of fins, well-developed hind limbs reduced disappear. Towering in the back of a strong central triangular dorsal fin is very prominent, male beast of up to 1.5 meters high, is not only offensive weapon, but also can play the role of the rudder. Mouth large, upper jaw of a 50 on a total of 40 large conical teeth, showing a vicious look. Distribution of killer whales in the world's oceans to the waters near the poles up in the country found the Bohai Sea, Yellow Sea and East China Sea, South China Sea and Taiwan waters. Killer whales like to live in the 12-13 ℃ from 0 ℃ to the colder waters of the small number of the warm ocean, even if there are often deep-water dive to a lower temperature zone. It is highly mobile operations, one day more than 100 kilometers will be able to swim, but more often appear within 30 kilometers from the coast waters. Swim forward very fast, at speeds up to 54 kilometers. Diving for a long time, up to 30 minutes. Killer whales prey mainly targeted at the various marine animals, such as dolphins, sea lions, walruses, etc., and sometimes predatory squid and cod, flounder, mackerel, sardines and other marine fish. Killer whales are ferocious, the ocean right whales, fin whales, humpback whales, gray whales, blue whales and other large whales are also afraid of a tiger to hurried away. When killer whales also use the trick prey, first the abdomen facing up, floating motionless in the sea, like a corpse, and when the squid, sea birds, sea animals such as close to it, suddenly rolled over , the open mouth to eat them. Killer whales like the solitary life, only a small group of 2-3, but also a large group of 40-50 only, there 2-3 hours a day to stay quiet water surface, because the lung is filled with enough air So can survive floating in the sea, exposing a huge dorsal fin. Group members to maintain regular contacts between the pectoral fins, appeared affectionate and solidarity. If the groups are the members of the injuries, accidents or lost consciousness, the other members will come to help, even with the top of the body or head with care, so that it can continue to float on the sea, is also tied into a bunch of sleep, This is to look after each other and maintain some degree of sober. People often travel at sea the whale said to be fickle siren, the fishermen were called "sea Overlord", film, theater and other art works will also describes it as "God of Vengeance", which killer whales in suggesting a man-eating animals. In fact, this is entirely people's imagination, as killer whales, though fierce and voracious sea monster, but never in history have not been eating according to the records of the case and even killed people have not heard of it. The strange thing is, it is not only harmless to humans, but show affable, in an aquarium can be kept domesticated, smart and obedient, but also learn many skills, performing a variety of programs, the most exciting show with "Welcome off ": With the ring will be a huge head out of the water, swam slowly to the audience, to show the" welcome ", or left to the breeder to ride in the back everywhere, even to the breeder who put his head into its giant mouth and motionless; "leap and swallow fish": breaking the water out of the open big mouth, jump to 5 meters high, to swallow a big fish hanging in there; "quick tour in the vertical jump": the first along the side of the pool Fast swimming, speeding through the waves, sometimes out of the water; "called upon to": hear the call signal, and immediately swim over; "cat and mouse": killer whale belly up, two pectoral fins above the surface, domestication and sat in it the chest, one hand on its teeth, with the killer whales in the water after a few laps on the pocket, he jumped into the water, time, killer whale catch up from behind, put his pack on his back again, and repeatedly repeated this action ... .... In fact, the killer whale is because people become so tame it's a weakness to grasp: when left alone the same kind of life, the courage to become small. Of course, after the brilliant performances, salmon, tuna and other delicious dishes as a reward is also essential. Orca: also known as killer whales, 8 to 10 meters in length and weighing several tons, and black back, white belly, curved dorsal fin up to 1 meter long and thin mouth, teeth sharp, fierce temperament, good offensive game, are penguins, seals the enemy. Sometimes it attacks similar baleen whales or sperm whales, a sea king. 1862, a 名叫埃斯里特 people, from a killer whale's stomach found 13 dolphins and 14 seals, therefore, naturally became the orcas executioner. English, Dutch name, which means kill the whale was intended. Are toothed whales, a huge black and white markings on the body, there are two oval white spot behind the eye, lateral direction has been outstanding behind the white area, the above characteristics it is easy to distinguish with other whales. Brutal gluttony, minke whales, dolphins, seals, large humpback whales, gray whales, beluga whales, and even animals in the "King" ╠ ╠ blue whales were caught in it as well. In addition, a variety of fish, seabirds, squid and other marine animals, and never easily let go. The most common way of their prey is attacking it. When fishing, they have a number of whales by the formation of a pocket, surrounded by fish, and then turns into the fish, a delicious dinner meal after they left. For fish, Wu Fu and other such small animals can be effortlessly put their phagocytosis, and for large mammals, the two sides will begin a desperate struggle. When they attack large animals, they often attack together. For example, someone might have witnessed the seven killer whales, minke whales attack a tragic scene: three able-bodied male killer whales, minke whales started on a fierce attack, a bite the tail, biting the head while the other end, and the remaining one attack from all directions, only 45 minutes, they put alive minke whales killed, and the remaining four will be surrounded them, and instantly sweep away put minke whales. Sometimes floating motionless on the sea, belly up, then a serious zombie. When groups of dolphins or sea lions swimming in the sea foraging, they often know the truth, they unwittingly close, then, a rapidly turning over killer whales, with lightning speed is _set_ to catch and eat it. Killer whale attack never took the initiative to humans, but also smart, willing to get along with people, a little training, can do all kinds of performances, we can see its a very good memory. However, in addition to the friendly side of the outside, it seems there is a strong revenge. Eskimo old man told me a true story: In Barrow, Alaska's northernmost town, two young Eskimos had a pair of killer whales shot missed, but was their revenge, in the next few years, as long as they a sea, that of the killer whale will come upon them, almost killed several times, they have been scared to the old, no longer afraid of the sea fishing.

In Washington state and British Columbia, killer whales live type, the basic community unit for small matrilineal groups, generally 2-9 close blood relations formed by killer whales, this will be long-term maintenance of stable matriarchal groups, all members seem to shared parenting work. Several of these groups will work together to form a "small group" (pod, usually used to describe the behavior of a group of social contact between each other cetaceans), a typical small group usually contains adult, juvenile male and female killer whales and whale Aberdeen , most of the female whale by the most senior leadership position (females are the family elders), but stay small group of whales is usually in the male offspring of the female whale. And even some male killer whales grow to 9 meters are still living in small groups. Small group of _set_tlers faced when other small groups have a special way to pay tribute: the face of some distance from each other closely arranged in columns of two lines, and two small groups of members would be mixed with each other, it seems that indicate their social status. Their small group of very harmonious (stable), stability (capture), only death (death) or captured (capture) in order to be destroyed. Each of them with a small group of social, resting, interdependent strong (socialize and rest in extended family groups, and literally thrive on each other's company)

Population Status
Killer whales are not in fear of extinction, but human hunting may have been caused by reduced populations in some areas. In Washington state and British Columbia, killer whales, either-or transit-type _set_tlement are only a few hundred head rest, and by pollution, heavy vessel traffic, and threats to survival and reduction of prey. Intensive whale watching may interfere with the killer whale's life, and those who farm in order to protect salmon from the people who invaded fins category killer whales may be expelled from their original habitat preferences. Tropical eastern Pacific is estimated there are about 8,500 whales in Alaska waters at least 850, probably up to 2000 off the coast of Japan over the summer in Antarctic waters about 8000 killer whale distribution, distribution to other areas within the scope of possible between several hundred to a thousand head. Currently in Japan (Japan), Indonesia, Greenland (English), and the West Indies (West Indies) the whalers continued to capture the killer whale, although less killing, but could have considerable impact. The most ferocious marine animals - killer whales, killer whales is a large toothed whales, the temperament is very fierce, so there are evil whales, kill the whales, killer whales, killer whales and other titles. It's physically strong and powerful, a large, was spindle, smooth surface, the skin beneath a thick layer of fat used to preserve body heat.

Distribution of killer whales in the world's oceans to the waters near the poles up in the country found the Bohai Sea, Yellow Sea and East China Sea, South China Sea and Taiwan waters. Killer whales like to live in the 12-13 ℃ from 0 ℃ to the colder waters of the small number of the warm ocean, even if there are often deep-water dive to a lower temperature zone. Its operations are highly mobile, able to swim one day more than 100 kilometers, but more frequently in less than 30 km from the coast waters, and less travel to the ocean. Swim forward very fast, at speeds up to 54 kilometers. Diving for a long time, up to 30 minutes. Shallow water in the Gulf area, also like to use the nick on the tail to hook Lahai algae, issued a "whirring" sound, and soon, the whole body to disclose full translucent seaweed. Although its teeth are very strong, but not as sharp as shark's teeth, it is mainly used to grab and not to chew the food was it and nm is the swallow. Prey mainly targeted at a variety of marine animals, such as dolphins, seals, sea lions, fur seals, walruses, etc., and sometimes prey penguins, squid and cod, flounder, plaice, mackerel, sardines and other marine fish class, there have been eaten by a killer whale and 14 dolphin 13 seals records. Groups of killer whales and even dared to attack ten times than the baleen whales, the scene with the lone wolves hunting deer is very similar to the first game surrounded up and down, to bite off dorsal fin, tail and so on, making it difficult to walk, and then tear to chunks of meat, and then bite off the lips and tongue prey. The killer whale is so fierce, so the ocean right whales, fin whales, humpback whales, gray whales, blue whales and other large whales are also afraid of a tiger, far met to hurried away, away. When killer whales also use the trick prey, first the abdomen facing up, floating motionless in the sea, like a corpse, and when the squid, sea birds, sea animals such as close to it, suddenly rolled over , the open mouth to eat them. Killer whales live in groups like the camp life, there is only a small group of 2-3, but also a large group of 40-50 only, there 2-3 hours a day to stay quiet water surface, because the lung is filled with enough air, so can survive floating in the sea, exposing a huge dorsal fin. Pectoral fin between the group members maintain regular contact with affection and solidarity appear, if there are members of the group injured, or lost consciousness accidents, other members will come to help, even with the top of the body or head with care, it can continue floating in the sea, is also tied into a bunch of sleep, this is to look after each other and maintain some degree of sober. If the humpback whale is a whale in the "singer", then the killer whale is a whale in the "master of language", and it issued 62 kinds of different sounds, and these sounds have different meanings. For example, in predator fish, it will send off the "loud noise sneeze" sound, as the force pulling rusty iron doors and windows, like the sound of the hinge, fish in the intimidation by the sound, the action becomes abnormal, and even on no response to the emergence of killer whales, not panic, scattered to escape, so it is easily wiped killer whales. Ultrasound can not only launch killer whale, through the echoes to find fish, but also able to determine the size of fish and swimming direction. The ability of the predators in the sea of life is very important, very dark water below, it is difficult in this environment to see distant prey target.

The strange thing is, it is not only harmless to humans, but show affable, in an aquarium can be kept domesticated, smart and obedient, but also learn many skills, performing a variety of programs, the most exciting show with "Welcome off ": With the ring will be a huge head out of the water, swam slowly to the audience, to show the" welcome ", or left to ride in the back of the breeder everywhere, even to the breeder who put his head into its giant mouth and motionless; "leap and swallow fish": breaking the water out of the open big mouth, jump to 5 meters high, to swallow a big fish hanging in there; "quick tour in the vertical jump": the first along the side of the pool Fast swimming, speeding through the waves, sometimes out of the water; "called upon to": hear the call signal, and immediately swim over; "cat and mouse": killer whale belly up, two pectoral fins above the surface, domestication and sat in it the chest, one hand on its teeth, with the killer whales in the water after a few laps on the pocket, he jumped into the water, time, killer whale catch up from behind, put his pack on his back again, and repeatedly repeated this action ... .... In fact, the killer whale is because people become so tame it's a weakness to grasp: when left alone the same kind of life, the courage to become small. Of course, after the brilliant performances, salmon, tuna and other delicious dishes as a reward is also essential. 1862, a 名叫埃斯里特 people, from a killer whale's stomach found 13 dolphins and 14 seals, therefore, naturally became the orcas executioner. killer whale / orca / Grampus in English, Dutch name, which means kill the whale was intended. Toothed whales are huge black and white markings on the body, there are two oval white spot behind the eye, lateral direction has been outstanding behind the white area, the above features are easy to distinguish with other whales. Brutal gluttony, minke whales, dolphins, seals, large humpback whales, gray whales, beluga whales, and even animals in the "king" - the blue whales were caught in it as well. In addition, a variety of fish, seabirds, squid and other marine animals, and never easily let go. The most common way of their prey is attacking it. When fishing, they will form a pocket by a number, surrounded the fish, and then turns into the fish, a delicious dinner meal after they left. For fish, Wu Fu and other such small animals can be effortlessly put their phagocytosis, and for large mammals, the two sides will begin a desperate struggle. When they attack large animals, they often attack together. For example, someone might have witnessed the seven killer whales, minke whales attack a tragic scene: three able-bodied male killer whales, minke whales started on a fierce attack, a bite the tail, biting the head while the other end, and the remaining one attack from all directions, only 45 minutes, they put alive minke whales killed, and the remaining four will be surrounded them, and instantly sweep away put minke whales. Sometimes floating motionless on the sea, belly up, just like a zombie. When groups of dolphins or sea lions swimming in the sea foraging, they often know the truth, they unwittingly close, then, a rapidly turning over killer whales, with lightning speed is _set_ to catch and eat it. Killer whale attack never took the initiative to humans, but also smart, willing to get along with people, a little training, can do all kinds of performances, we can see its a very good memory. However, in addition to the friendly side of the outside, it seems there is a strong revenge. Eskimo old man told me a true story: In Barrow, Alaska's northernmost town, two young Eskimos had a pair of killer whales shot missed, but was their revenge, in the next few years as long as they are a sea of killer whales that will come upon them, almost killed several times, they have been scared to the old, no longer afraid of the sea fishing. Water column Killer whale water column is tilted, thick and short, like baleen whales, like, thin and high.

Basic data
Comparison with the human body length at birth weight: 2.2 ~ 2.6m, 160kg Killer whale Size: male 14-15 years old mature normally. This time should be 5.5-6.1 m, female sexual maturity at 8-12 years of age when the age is 4.6-4.9 m .20-25 is a long to fully mature greatest when the more reliable and often used as a reference adult male size is generally 19 feet to 27 feet (6.7-8.2m) between the (Mitchell 1975), often in the 8,000 pounds to 12,000 pounds (3,628-5,442 kg) . the largest recorded in 32 feet. (9.75 meters) and 21,000 pounds (9,524 kg). was recorded in 1984, Perry Blue and Rayleigh adult Muhu whales typically 16 feet to 24 feet. (5.2-7.3 meters), weight 3,000 pounds to 8,000 pounds (1,361-3,628 kg).'s largest recorded record is 28 feet. (8.53 m) weight 15,000 lbs (6,803 kg). also wear blue and Rayleigh in the 1984 report. According to (IWC, 1981) had captured the 2661 North Atlantic killer whales, long term, the average male recorded at 6.1 meters (20 feet) whale averages of 5.5 females meters (18 feet). But in 1998, Bernard was a documented and Rayleigh in the Pacific Northwest males average 7.20 meters, while the Northwest Atlantic of 6.17 meters. adult male pectoral fin large individuals up to nearly 2 m, reaching 20% of body length, 1.2 meters wide, while the female is 11-13 %, large individuals of male dorsal fin up to 1.8 meters, 2.7 meters wide, caudate lobe, female dorsal fin is 0.9 meters.

Population Status
Killer whales are not in fear of extinction, nor are any protected species, but human hunting may have been caused by reduced populations in some areas. In Washington state and British Columbia, killer whales, either-or transit-type _set_tlement are only a few hundred head rest, and by pollution, heavy vessel traffic, and threats to survival and reduction of prey. Intensive whale watching may interfere with the killer whale's life, and those who farm in order to protect salmon from the people who invaded fins category killer whales may be expelled from their original habitat preferences. Tropical eastern Pacific is estimated there are about 8,500 whales in Alaska waters at least 850, probably up to 2000 off the coast of Japan over the summer in Antarctic waters about 8000 killer whale distribution, distribution to other areas within the scope of possible between several hundred to a thousand head. Currently in Japan (Japan), Indonesia, Greenland (English), and the West Indies (West Indies) the whalers continued to capture the killer whale, although less killing, but could have considerable impact.

Mouth large, upper jaw of a 50 on a total of 40 large conical teeth, showing a vicious look. Distribution of killer whales in the world's oceans to the waters near the poles up in the country found the Bohai Sea, Yellow Sea and East China Sea, South China Sea and Taiwan waters. Killer whales like to live in the 12-13 ℃ from 0 ℃ to the colder waters of the small number of the warm ocean, even if there are often deep-water dive to a lower temperature zone. Its operations are highly mobile, able to swim one day more than 100 kilometers, but more frequently in less than 30 km from the coast waters. Swim forward very fast, at speeds up to 54 kilometers. Diving for a long time, up to 30 minutes.

As delicious whale meat, a lot of fishermen are fishing the sea whales, a gun or a special fishing tool to kill him after ashore anatomy. Because long-term capture killer whales, it significantly reduced, and the recent air pollution, marine pollution, making the killer whale's survival greatly reduced.
