About Seals
Cuyuan body was spindle seals, weighing 20 to 30 kg. The body is short-haired, blue-gray back, abdomen, breast yellow, with blue-black spots. Head nearly round, large round eyes, no external ear, kiss short and wide, long and stiff upper lip whiskers, was shaped beads. Limbs are with 5 toes, webbed toes, forming flippers, with sharp claws. After the large flippers, back extension, short, flat tail. Coat color changes with age: cub color depth, light color into a beast. Seals are carnivorous marine animals, mammals. They streamline body, limbs into flippers, suitable for swimming. Seals have a thick subcutaneous fat, warm, and provide food reserves to produce buoyancy. Seal habitat in the sea most of the time, hair removal, only to land or ice breed to live. Seals located in the world, especially in the cold polar waters and more food based on fish and shellfish. Sea lions, seals, walrus is a close relative, they have ears, hind legs can turn to the front to support the body.

There are 18 species worldwide seals, the Arctic region 7, the Antarctic region 4. However, in quantity, the Arctic than the Antarctic seals and more. Drink all the world's seals showed a spindle-shaped body, suitable for swimming, the head round, looks like dogs. At present, the world's oceans, many types of existing seals, a total of 13 genera and 18 species. The largest number to the Antarctic, followed by the Arctic Ocean, North Atlantic, North Pacific and other places. Divided into the following specific case: 1, the harbor seal is phoca linnaeus Harbor seal body length 1.5-2 m, the maximum weight of 150 kg male, female 120 kg. Spotted seals are widely distributed, mainly in the northern hemisphere high latitudes in China are mainly distributed in the Bohai Sea and Yellow Sea. Mainly feed on fish, also eat cephalopods and crustaceans. 2, the bearded seal is erignathus gill Called bearded seal bearded seal, because of its stubby snout dense growth of beard is named. The longest beard length 14 cm, the upper lip whiskers on each side of about 106. Male body length 2.8 meters, 2.6 meters in length female, average weight 400 kg. Brown-gray or gray-brown body, the back color of the central line of the deepest, the abdomen gradually shallow, no markings. Bearded seals are mainly distributed in the Arctic Ocean, North Atlantic, North Pacific, is not located in the southern hemisphere. Pingyang County, Zhejiang Province in China in 1972 was caught by a sea area 176 cm in length and weighing 71 kg in the male beast. Bearded seal the main predator of benthic animals such as: shrimp, crabs, mollusks, and Yong, flounder and other bottom-dwelling fish, but squid prey. 3, the gray seal is halichoerus nilsson Grey seal males is about 3 meters and weighing about 300 kg, females about 2.3 meters and weighing 250 kg. Into the neck of the male animal is very thick, and 3-4 wrinkles, which is the difference between it and one harbor seal. Is widely distributed gray seals, the Arctic Ocean and the Atlantic Ocean are distributed, the number of existing about 2.5-5 million head. Grey seal diet is broad, but mainly fish. 4, ringed seals are pusa scopoli This is a: ringed seals, ringed seals of Lake Baikal, the Caspian Sea ringed seals. All seals ringed seals, the body a minimum. Length of 1.4 meters big stallion, weight 90 kg, face like a cat. Ringed seals a wide range of feeding habits, never spinal animals to fish, the total number of more than 75. Its main predators are polar bears and polar shark. Ringed seals, mainly in the Arctic Ocean, Okhotsk Sea, Bering Sea, the Baltic Sea, Lake Ladoga and Lake Baikal, the Caspian Sea. 5, seals are histriophoca gill bands The species of seals in the seal is also a small species. Male is dark blue and gray or dark gray purple red purple, has a very wide around the neck ring vaginal discharge. Females body pale, grayish brown or dark brown dark gray base. Only bands seals inhabit the northern hemisphere, mainly in the Bering Sea and Okhotsk Sea, hi habitat away from human habitation on the ice or on the island, not a large group, food was mainly pollock and cephalopods. 6, harp seal is pagophilus gray Harp seal harp seal known. About 1.8 meters in length and weighing 180 kg. White or brown-gray body, shoulders at the diagonal from the back end of a "∧" type of black belt, saddle shape resembling named harp seal. Only distributed in the Russian Arctic north, around Greenland and the north of Canada and Newfoundland, mainly feed on fish, crustaceans and molluscs. 7, monk seals are monachus fleming Monk seal head is round, and is fine short hair, head look like a monk, named monk seal. The species of seals has become a very rare animal only distributed in latitude 20 ° to 30 ° of the Hawaiian Islands chain of islands under the wind, the Caribbean, the Black Sea. 8, Weddell seals are leptonychotes gill Weddell seals hi habitat in Antarctica associated with the fixed ice, is the most southerly distribution of mammalian species, is more common in Antarctic seals. Its strong ability to dive, you can dive into the depths of more than 600 meters, sustained 43 minutes, diving fins Le capacity in the highest animals. To predatory fish (sculpin) and squid for a living. 9, Ross is ommatophoca gray seals Ross, the number of seals in the Antarctic seals at least one. The neck is very thick, the contraction of neck skin folds can form large, the first to indent to, almost completely hidden in the neck fold, it also issued a similar bird sounds. Mainly distributed in the ice around the Antarctic continent with the vicinity. 10, leopard seals hydrurga gistel type Like the leopard seal leopard spots not only has the temperament, and also like a leopard, is the seal of the most brutal kind. It addition to predatory fish and squid, but also eats temperature animals eat penguins and other birds and even whales, other seals. Line from the ice of Antarctica to Australia, New Zealand, South America, Africa and around the southern islands are distributed. 11, crown seals are cystophora nilsson Crown seals when faced intimidation or excitement, the nose can be expanded into a snout in front of cystic processes, people and the nasal seal for the capsule. Mainly in the North Atlantic and Arctic waters, the main food for fish. 12, the pictograph is mirounga gray seals Pictographic seals are the largest type of seal families, it features male beast nose, in the excitement or anger can be expanded. This is included: Southern elephant seals and northern elephant seal type. The maximum length of up to 6.5 meters, weight 3600 kg, it is the fins of individual heads the largest animals. 13, crab-eating seals are lobodon gray Crab-eating seals mainly feed on krill, baleen whales diet and similar. Hi gregarious, smart and fast in the ice activities, mainly in the Antarctic continent around the Antarctic coast is also unique to animals.

Habits
Seals live in cold temperate seas, in addition to calving, resting and molting season need to ice, sand or rocks, the rest of the time swimming in the sea, feeding or playing. Breeding season did not cluster, Aberdeen animals after birth, a family group, breast-feeding after the end of the family group. Litter on the ice, when ice melts, the cub began to live independently in the water. After a few breeding individuals have had to push along the beach in the litter. On fish as the main food, fresh crustaceans and cephalopods. Pinniped Seals is the most widely distributed of a class of animals, from pole to pole, from sea water to fresh water lakes, has a seal footprint. The number of Antarctic Seals, followed by the Arctic Ocean, North Atlantic, North Pacific and other places. Pinniped Seals are a big family, the world total of 19 species. One has a nose like a seal can be inflated; head shaped like a monk's monk seals; wearing white bands with a pattern of seals; body color mottled seals; male beast head with a black crest crown seal skins. Not seal the body, only 1.5 meters to 2.0 meters long, the biggest one weighing 150 kg, females slightly smaller, weighing about 120 kg. Drink all the world's seals showed a spindle-shaped body, suitable for swimming, the head round, looks like dogs. Seal pool at the Waterfront Park, seals swim all day playing in the water and lively, it is cute. If you train them to play ball, it will show programs. Seal round the body, such as spindle-shaped, mottled body color, hair is sparse, thick subcutaneous fat, appears to Biaofei body fat. Constant stretching back two hind legs, webbed feet like a diver. Travel from the beach, the feet swing around in the water, push the body forward quickly. From the seal's head to see, looks like dogs, so many places called seals. Sometimes it climbed the rocks, then it becomes extremely clumsy moves, good at swimming limbs play a supportive role only. Seals crawl very interesting movements, often causing the viewer so the bright laughter. Under natural conditions, seals and sometimes wandering in the sea, and sometimes shore leave. High tide when the sea shore can be more choices within the submerged sandbar and the shore of the reef Bay. For example, winding estuary in China's Liaoning and Shandong Temple Islands and other places have often found a large group of seals come and go. Strong seals swimming skills, speed of 27 kilometers per hour, while good diving, and can be submerged about 100 meters in the Weddell seals, Antarctic waters are able to dive to 600 meters deep, sustained 43 minutes. Predatory fish and seals of various cephalopods, sometimes eat crustaceans. It is a great appetite, a 60 kg to 70 kg of seals, the day to eat 7 kg to 8 kilograms of fish. Seal of social practice "polygamy" system. In estrus, the male began to chase the female seals seals, seal the back of a female only male seals are often followed by a few, but the female seals only _select_ one from the male seals. Therefore, the male seals fight between the inevitable to happen, wild seals give each other a violent injuries: the other side with some teeth bite hard male fur seals have thus torn and bloody. Fighting is over, the winner and the mother seal with more water in the water to mate.

Economic value
High economic value of seals, delicious meat, and possessed a wealth of nutrition; cortex tough, can be used to make clothes, shoes, hats, etc. to withstand the cold; fat can be used to extract the oil industry; male seals the testicles, penis, sperm Cable is extremely valuable medicines, commonly known as seal kidney, together with other medicines prepared from traditional Chinese medicine, with brain and kidney, blood and the germ of the special effects impotence; gut strings are made of fine materials; liver rich in vitamins , is a highly valued tonic; teeth can create exquisite handicrafts. Because of this, the killing of seals was severely. Especially the United States, Britain, Norway, Canada and other countries send each year a large number of well-equipped fishing boats at sea wantonly swept seal catch, and many seals, particularly seals, Greenland seals and reduce the number of crown was particularly high.

Seals Division
Seal Section phocidae member body fat, subcutaneous fat, the neck thick round head, hind legs and tail together, always back in the land can only crawl with the body's motility and advanced, very stupid, but it is quite flexible in the water , and good diving, you can dive into the depths of several hundred meters. Seal Bureau members can be divided into north and south roughly two kinds of groups can be divided into two subfamilies phocinae placed seals and monk seals subfamily monachinae, basically limited to the northern distribution of seals subfamily, and monk seals out of the southern hemisphere outside of the subfamily, in the northern hemisphere can also see the south. Northern seals are usually small size, body length and more than 2 meters, mainly in the Arctic Ocean, in the North Sea can be seen in all temperate. Seals in the North is the distribution of the most familiar in the North Atlantic and North Pacific harbor seals (harbor seals) phoca vitulina and large teeth seals phoca phoca largha, which can be found in China Yellow Sea and Bohai area. Seals in the North Baikal seals is rather special phoca (pusa) sibirica, located in Lake Baikal, is the only freshwater seal, and its not clear how to get there. Another distribution of seals in the lake is the world's largest saltwater lake located in the Caspian Sea Caspian Sea Leopard phoca (pusa) caspica, Caspian Sea may not yet be to come here when the lake. Southern seals usually larger size, of which the largest size mirounga angustirostris male Southern elephant seals can weigh up to 3 tons, is the fins in the size class is the largest carnivorous members. Southern elephant seals in the Antarctic and Subantarctic distribution area, there is the distribution of northern elephant seals in the North American West Coast mirounga leonina, southern elephant seal distribution very different, but both are very similar. Elephant seals not only great size, but also retractable nose, and the like quite some similar, sometimes also known as elephant elephant seal, walrus Section walrus easy and confusion. Seals in the Southern members of the Northern Hemisphere there are several monk seal monachus, including the Mediterranean monk seal monachus monachus, monk seal monachus schauinslandi Hawaiian monk seals and the Caribbean (West Indian monk seal) monachus tropicalis three, is to adapt to the warm waters of the seals, Today the number has been very rare, in which the Caribbean monk seal extinct. Seals in the south is the most special temperate to Antarctic waters south leopard seal hydrurga leptonyx, leopard seals are the only staple food of seals in warm-blooded animals, big mouth, swimming fast, predatory seabirds and other sea animals. Leopard seals and other seals of different, mainly in forelimbs to the water, rather than the hind limbs. Crab-eating seals, leopard seals lobodon carcinophagus is a close relative, both the size and distribution are similar, but the habit far behind. Crab-eating seal crab is not eating, but as large numbers of krill in the southern seas for food, krill to the South Sea animals provide a rich food, crab-eating seal is one of the largest number of seals. There is also a seal called the fur seals, so named because the skin is very rough. Spring is their breeding season.

Seal oil
Main Material: seal oil, gelatin, glycerin seal oil in each capsule contains: dpa (c22: 5) 4.15% epa (c20: 5) 7.53% dha (c22: 6) 9.48% omega3pufa s 22.59% 2.52 squalene % other fatty acids 53.73% Dosage: 2 capsules, twice daily Storage: Sealed cool and dry place of origin: Canada biopotency enterprises.ltd. o-power seal oil is rich and comprehensive essential to human health多 carbon omega-3 polyunsaturated fatty acids and their ingredients and effectiveness are: the rich epa (eicosapentaenoic acid): Known as the "vascular scavenger" to prevent hardening of the arteries and heart with blood clots and reduce high blood pressure and cholesterol, inhibit platelet aggregation and other effects, the use of coronary artery disease, thrombosis, stroke, stroke, cerebrovascular disorders, high fat steroids, high blood fat, blood vessels, accelerate the microcirculation and other health functions. Rich dha (docosahexaenoic acid): commonly known as "Brain Gold" is the development of brain function and optic nerve function indispensable material, can promote the intellectual development and improve the IQ of children taking to help the nervous system and mental development young people taking to help neurological health and enhance memory, adults taken, can improve efficiency, elderly people taking to help control and treat Alzheimer's rich dpa (twenty-two EPA acid): In human milk and high levels of dolphin oil, fish oil and the lack of variety of food, baby milk lost lost dpa, dpa epa10-20-fold higher efficacy. It can promote and enhance the body's immune system. dpa and dha synergistic effect on type ii diabetes, rheumatoid arthritis, psoriasis, ulcerative colitis and other significant role in the size of a wealth of squalene (squalene): This is the fish oil and other animals do not contain or content very few effective natural anti-oxidants, have significant anti-cancer and anti-cancer effect, it has the unique role of the strong anti-free radical moisture for maintaining smooth and elastic skin has a magical effect. o-power pure seal oil of excellent quality: rich and comprehensive omega0-3 polyunsaturated fatty acids of carbon 多: General epa fish oil contains only and dha, with little or non-dpa, the dpa is to improve the human immune system is not just the lack of the necessary ingredients, seal oil contains not only epa and dha, more rich in dpa, dpa ratio in human milk is essential nutrients, the development of the neonatal immune system plays an important role and intellectual development. pure oil: fish oil is usually from fish heads, fish bones and fish offal extracted from the extraction process is complex, and inevitably will bring a variety of undesirable material, and seal oil is pure fat from the seals of the natural oil extracted, very clean health. Specific soluble substances: seal oil contains a unique warm-blooded human beings belong to the same fat-soluble substances, non-normal cold-blooded fish oil, is very close to human milk, is extremely valuable nutrition. Rare resource: the Arctic harp seal is a cold-resistant mammals It lives in temperatures as low as -40 degrees Celsius in the cold near the Arctic Circle, mainly in luxury and cold Arctic deep-sea cod fish for food, strong reproductive ability. After 20 years of research scientists. that the rich Arctic harp seal accumulation of subcutaneous fat layer rich in long chain polyunsaturated fatty acids of carbon omega-3. The essential fatty acids on human health and longevity, because the Canadian government developed a policy of hunting quotas, combined the more precious natural resources, seal oil is the world of human need qmega-3 polyunsaturated fatty acids 多 the best carbon source, is the twenty-first century, why do humans need the best natural high take seal oil supplements? long chain polyunsaturated fatty acids of carbon to prevent heart vascular disease, cancer, anti-inflammatory, anti-aging has a significant effect. Seal oil in human pancreatic fatty acids in the digestive process and play a role, so the body seal oil can be fully absorbed. o-power of natural Arctic harp seal capsules in Canada the government's "export of food production license", contains a wealth of omega-3 intestinal absorption by the body directly, without breakdown by the liver, without any side effects, long-term use does not harm liver and kidney, lipid-lowering does not really hurt the liver, is the most advanced technology and highest quality of modern Arctic harp seals a perfect crystal. Federal Institute of Experimental Biology (faseb) warning in order to maintain optimum good health and extend life span, amount per person per day should eat omega-3 ratio of at least 1-2 grams, and is now a daily intake from food was only 0.3-0.5 grams, less than the standard 50% or more. Background: early 70s, scientists have found that living near the Eskimos in the Arctic, although they eat a lot of saturated fat and cholesterol (compared to other groups, more than 2 times higher) and they note the very low density lipoprotein (vldl) and cholesterol is very low, and their cardiovascular, hypertension, and cancer prevalence is very low, because the Eskimos in their daily lives are often consumed Arctic harp seal fat! With the progress of modern civilization, it completely changed Yushi content, by the flavor of game, wild vegetables and hunting and so obtain the omega-3 long chain polyunsaturated fatty acids drastically reduced the carbon in the artificial cultivation and breeding of agricultural and livestock products in onega-3 were very low, at the same time and a lot of very high consumption of food containing omega-6 vegetable oils, and further promote human Ω-6 and Ω-3 suddenly from original 1:1 ratio of 30:1. With job strain and stress, bacteria erosion deepened the two unsaturated fatty acids the body imbalances, so that cell function and the body can not function properly, the final result, such as cardiovascular, respiratory tract, and decreased immune function, and likely to cause cancerous cells and tissues of children, this serious imbalance can cause brain and the nervous system dysplasia. World Health Organization believes that the modern human body should be Ω-6 and Ω-3 ratio of 30:1 down to 4:1 from the current or at least reduced to 10:1, the most effective remedies is a direct complement epa, dpa high nutrients, and sealskin contains not only the fat under the epa and dha master also contains dpa, the three unsaturated fatty acid content of the seal up to 25%, so the Arctic harp seal oil is the most effective nutritional supplement omega-3 . epa (eicosapentaenoic acid): commonly known as "vascular scavenger" to prevent hardening of the arteries and heart with blood clots, lower blood pressure and cholesterol and so on. For coronary artery disease, stroke, cerebral hemorrhage, cerebrovascular disorder, hands and feet numbness, palpitations and other cardiovascular and cerebrovascular disease. dha (docosahexaenoic acid): commonly known as "Brain Gold" is the brain and optic nerve development and function of playing the material must be to promote infant development and IQ intelligence, enhance memory, prevent and treat Alzheimer's disease . dpa (twenty-two EPA acid): The content of human milk and seal oil is high, fish and other foods are lacking. It can promote and enhance the body's immune system, diabetes, rheumatoid arthritis, psoriasis, colitis, which are the size of the treatment effect. qualene (squalene): natural antioxidant, anti cancer and anti-cancer and the role of beauty, which can effectively keep the skin moist and smooth and elastic. Fat-soluble active substance: for improving the body's own immune system and regulation of insulin secretion with special effects. Prevention and treatment of rheumatoid arthritis, lupus and so on. Form of diabetes is also inhibited. First, the benefit of mankind seal oil For a long time, the world medical community found living near the Eskimos in the Arctic, very few people with cardiovascular, hypertension and cancer and other diseases. To the seventies, Canada by a number of studies have concluded, MD, Eskimo diet is mainly seal oil, seal meat and fish, because these foods are rich in omega-3 fatty acids, so it does not cause them to suffer These modern "diseases of civilization." Second, seal oil contains what elements? Seal oil is extracted from a kind of seal fat tissue is rich in omega-3 fatty acids precious nutritional supplements. Seal oil contains about 20% to 25% of the omega-3 polyunsaturated fatty acids, and its content is the most animals in nature. Also, seal oil contains a certain amount of squalene and vitamin e. Third, the same supplement omega-3, taking the seal oil and fish oil What is the difference? (1) natural seal oil contains about 20% to 25% of the omega-3 fatty acids, more natural fish oil content is much higher. (2) seals are mammals with man, while the fish is a low cold-blooded. Mammals omega-3 polyunsaturated fatty acids in position on the triglyceride and fish are different. Omega-3 in the mammalian one, three, while fish in the two previous. The digestive process in the body, one, three on the omega-3 is easy with the lipase, decomposition as a free state of the fat more easily absorbed by the body. Therefore, absorption and utilization of fish oil, seal oil than high. (3), seal oil contains 5 to 6% of the dpa, while fish oil contains little dpa. Found, dpa growth of young children is essential, and the effect is commonly known as brain dpa gold dha more than tenfold. (4) omega-3 unsaturated fatty acids because of the reason, it is easy to be oxidized into peroxides, harmful. Seal oil contains a natural anti-oxidants, can seal oil cooking at high temperatures under 190 degrees is not oxidized. Fish oil does not contain anti-oxidants, so it is easy to deterioration at ambient temperatures. (5), seal oil contains 2 to 3% of squalene, a substance with the prevention and treatment of cancer. At the same time, it has the function of activated cells, which can effectively protect the skin, and can inhibit the absorption of bad cholesterol in food and speed up their metabolism. (6), seal oil is almost free of cholesterol, and most fish oil contains a lot of cholesterol.

Baikal seals
Baikal seals is the only freshwater seal lives in, but also the smallest on earth a fin Amphipoda animals. Life in general in the 30 to 35 years, the highest recorded for 43 years. Baikal Lake Baikal seals distributed throughout, but they prefer to stay away from the shore, the center of the island relatively quiet, often tens of hundreds of white pebbles in the sun. They feed day and night in all kinds of fish in the lake. Here is the black bear hunting except for the occasional seal outside the main natural enemy is man. Baikal seals long and strong claws to break the ice, open hole permeability; its well-developed circulatory system, can store large amounts of oxygen, suffocating in the water to more than 1 hour to reach the 300 meters of water. Because size is very large (adult seals weighing more than 100 kilograms), where each seal thirty-four kg per day to eat the fish, almost 2 tons a year to eat a variety of fish, and is basically a predator by night obtained. Baikal seals like activities in groups, and highly intelligent, trained, they will perform many of the programs. Late February to early April each year when the frozen Lake Baikal lake Baikal seals when the breeding season is. Females typically give birth to a litter of pups only. 2 ~ 3 months for litter size in the pack ice, Tsai animal was a white lanugo slender, 2 to 3 weeks after the slough off, breast-feeding period is about 3 months. Female average of 3 to 6 years, 4 years of male sexual maturity.
