Like whale very much all the time as a child this kind of biology, live in blue sea, type of build or figure is gigantic let a person plaint for it again. Whale resides chordate door, vertebrate inferior the door, lactation key link, true animal subclass, included about 98 kinds of lives to there is viviparous mammal mediumly in marine, river. Chinese maritime space has more than kinds 30. "Whale " itself definition is vaguer, whale eye can include all whale kind, the whale that still has specific family kind. Dolphin still includes in whale eye, homicide whale and tycoon whale belong to dolphin (Delphinidae) division. Whale looks main component is two specific item: Beard whale (Mysticeti) with tine whale (Odontoceti) . The sort that needs whale is less, but type of build or figure is gigantic, current and foregone the smallest phyletic body length also exceeds 6 meters, la Jingye belongs to the biggest animal on the world. Difference of tine cetacean bodily form is bigger, the smallest phyletic body length is only 3 decimetre left and right sides, the biggest -- cachalot also is in 20 meters of above. On weight, at present the biggest whale has sixty thousand and ten kilograms to weigh, the smallest also 2000 kilograms are weighed. Whale does not belong to fish. Whale belongs to lactation kind.
Whale of the Dragon KingWhale of the Dragon King (formal name: Basilosaurus, meaning for imperial lizard) , whale of renown instrument tine (Zeuglodon) , already the archaic ocean of become extinct is mammalian, of contemporary whale near, it is whale kind a medium kind, live at the 39 million the Eocene Epoch before coming 34 million years terminal. Whale of the Dragon King just began to be considered as tremendous marine reptile fossil by accident, name imperial lizard so. It is the earliest be discovered in American Louisiana city, subsequently paleontology home exists at least from the make out in Egypt and the fossil that Pakistan discovers two plant otherly. Average length is whale of the Dragon King 18 meters, can amount to 21 meters most, nevertheless that is doubt is like whale of the Dragon King only. And have more more slender than contemporary whale body. The smallish hind legs that paleontology home has degraded to them is interested very much, because it can prove contemporary whale is original,be give birth to lactation by land kind animal evolution and come. Whale of the Dragon King also is the fossil that close cc compares city and Alabama.
Animal introduction
Whale of the Dragon King, call imperial lizard, instrument tine whale again, it is division of whale of the Dragon King is belonged to medium, be considered as the ancestor of contemporary whale, live at late the Eocene Epoch about 45 million - 36 million years ago, already eradicated now. The rat white shark that the natural enemy that at present science studies to discover it may be shark fish. Whale of the Dragon King is carnivorous sex animal, body length (Length) is 18 ～ about 21 meters.
Instrument tine whale is the original whale with foregone people kind one of, it comes by terrestrial animal evolution, subsequently it enters melt into further again two kinds of contemporary whale kind. Although belong to a cetacean kind, but the appearance feature of instrument tine whale is mixed however tremendous sea snake is similar, when it is discovered first, paleontology home once still regarded it as is reptile.
The mammal that has the most powerful occlusive force or for prehistoric whale. Whale of the Dragon King lives before all ages of the ~3400 40 million years ago, and with preying other whale is feed. In fact, pass an analysis just about another kind of prehistoric is cetacean -- the skull of again and again of bruise of lance tine whale, the scientist just is able to evaluate the occlusive force of whale of the Dragon King. Researcher is based on the scathing rate of skull of lance tine whale, computation gives this to plant aquatic the head that the person that prey can smash to exceed 1600 kilograms to weigh.
The skeleton of whale of the Dragon King alludes animal of its traceable land: A pair of bound feet. Although the fossil of Egypt often does not get be savinged goodly, but in the thorax of fossil of instrument tine whale finds posse fish fossil. This is the thing inside its stomach it seems that, include a few kinds of different fish anatomy among them, and a 50 centimeters long shark, enough proof: Whale of the Dragon King is not the animal of disposition docile.
Characteristic
In the desert of Egypt, have a whale kind the strange place that anatomy Sha Zhongshi gives, " the cereal of whale " the fossil that is a decharge is vestigial, before 36000000, whale kind often swim close here bank. Two kinds of whale that instrument ages whale is here place discovery kind one of. The coastal water area of warmth of late the Eocene Epoch special marine like contemporary tropics, the home of whale of tremendous tine of inchoate and cetacean instrument is over there.
Instrument tine whale is a kind giant and cetacean. They that enormous size means them to need much food to keep organism, people guesses most instrument ages whale all day leisurely swims in shallow sea, search potential prey.
Instrument tine whale is belonged to eat the meat kind animal, it is short and sharp tooth is to be used capture of shark and other prey. Differ with the whale that puts only at present, instrument ages whale does not have spiracle, so this is planted giant and marine biology of ancient time must breathe ability of head smell surface. Instrument ages the special place of whale still depends on, over there its terrestrial ancestor from it bear passed a pair of bound feet. Instrument tine whale is not one kind very captious sweep past the person that feed, fish, shark, cuttlefish, chelonian and other and marine mammal are on its cookbook. Instrument ages whale can use it to the eyesight of acumen and audition are searched and capture prey. Like contemporary whale, instrument ages whale is breathing airy, it cannot be waited for for long in underwater. Instrument ages the nostril of whale is not born in the top of head, become it so rise when must carry the coping of nose from surface. Whale of the Dragon King is the means like similar eel comes activity. More eccentric even is, whale of the Dragon King also is met possibly below a few circumstances with the level be like the means like eel to move.
One horn whaleOne horn whale (Narwhal) call ice again whale, alone horny whale, horn whale, it is division of one horn whale among them a sort, and this sort has a variety only.
Tooth of one horn whale grows female normally in gum, but male left tooth can be born, become a long tooth, can be as long as 3 meters.
One horn whale may be one of the most mysterious animals on the world, they live in arctic water area only, speed is splitting, appear and disappear mysteriously, call ocean again alone horny animal.
Be in mediaeval, the tooth of one horn whale is regarded as alone the horn of horny animal sells as far as to Europe and East Asia, doctors believe a horny pulverize to be able to treat 100 disease.
One horn whale basically distributings to surprise at Hunan division the maritime space such as bay of the sea, the Arctic Ocean, Ba Fen, Greenland sea.
Animal introduction
Height of arctic horn whale 6 meters, chin to grow ahead on male or two 2.4 ～ grow straightforward helical horn 2.7 meters, be similar to the pike of mediaeval reshipment knight. People has not make clear Hunan this horn to there is what use in the life of horny whale.
Of horny whale " horn " solid for one gigantic tine. From its embryonic development looks, the tooth of horny whale shares 16, just degrade to tooth of the much when be born disappeared, only two palatine reservation come down, and the tine of female whale is lifetime concealed at palatine and show nothing more than, only a male whale is left, break through labrum to be extended ahead, its length can amount to 2 ～ 3 meters, be like the pike of mediaeval reshipment knight quite; One on the right side of also hides and do not show. But fall in extremely individual situation, its grow tine twice to also have what extend ahead at the same time, that became dual role whale.
Happy event of one horn whale is social, it is 5 ～ are 20 times normally a flock of, disposition is docile, it is with fish feed. Horny whale body length 4 ～ 5 meters, weigh 900 ～ 1600 kilograms, n shows white almost, rear black, adorning few and far between blue ash and black stain. One hero is belonged to on reproductive means much more female, melt every year when ice and snow when, the one horn whale of gang begins to forage, play in the sea copulate.

Characteristic
Alone horny whale breeds in winter, they are copulatory in underwater ice acupuncture point. That is the coldest when, inside the Arctic circle inky, air temperature can fall 51 ° C. Of wind and ocean current erode gap leaves in putting a layer on the ice, let alone horny whale can swim to surface take a breath. As a result of exceeding chill, whale-calf is born very strong. Grown alone horny whale body length makes an appointment with 12 feet, make an appointment with 2000 pounds again. Whale-calf lifetime comes down, bulk is equivalent to maternal 1/3, the darling with huge bodily form is in mammal. Like white whale and arctic right whale, alone of horny whale body 50% for adipose; The proportion that fat of other whale lipoid holds the body is about 20% to 30% . Had seen without the person alone the appearance that horny whale eats in underwater. Lai heart ever had studied 121 alone the stomach of horny whale, discover they are on a diet in the summer, take food in winter insanity.
Because like to eat deep-sea living halibut, alone horny whale is good at phreatic water. The Denmark of Lai heart works in the same place Madesi Yaogensen at going up 90 time initiate gives the century alone horny whale installation is tracked implement technology, his tracker often is in deep-sea because cannot bear,tall crush is cracked. Whale kind having the thorax that can compress, according to the account of tracker, they can go to 1800 meters in.
As the arctic species that gets protection, alone horny whale is a social animal, basically live in Atlantic boreal end and maritime space of the Arctic Ocean, also discover in Greenland sea a few alone horny whale. Because button spy person likes hunt alone the long tooth of horny whale, flesh and skin. The scientist is early know, alone horny whale can be in the sea with approximately perpendicular angle submergence about 900 meters, and repeat such act for many times everyday, saying to go up absolutely is phreatic water ace.
Finback (formal name: Balaenopteraphysalus) , whale of name long bed mat made of woven stripe of bamboo, fin whale, chief merit whale, it is one of needing whale to belong to aquatic mammal. It is the whole world the 2nd big whale, also be existent the 2nd big animal, be next to blue whale. Finback bodily form is shown spindly, about 25 meters long, weight makes an appointment with 70 tons. Odd or 2 ～ 3 an activity, the summer migrates all alone of cold water maritime space entices, winter breeds to warm maritime space. Finback is not stood by commonly coastal. Highest speed per hour is 20 sea mile, submergence deepness 200 meters of less than. Food is phosphorous shrimp kind, branny shrimp kind, oar is sufficient kind wait for small-scale test animal, also eat herring fish, Qiu Dao fish, hairtail to wait group swim sexual fish and cuttlefish. Basically distributing in antarctic maritime space. Finback is caught in great quantities during 20 centuries, belong to endangered species.
Animal introduction
Taxology home already was opposite a long time ago finback is known somewhat, 1675 horse of · of the gram in first degrees of You Fulai heart lows (Frederick Martens) publish the taxology material that concern, amounted to heart benefit by Paul · 1725 again ever since (Paul Dudley) publish. These become Carl Linnai to describe the important reference of this species later to the description of finback, will name in all for Balaena Physalus (1758) , plant in the center the Physa in adding a word comes from Greek, mean jet. This formal name all the time continue to use comes at the beginning of 19 centuries, till French nature learns a Boneide Lasaipeide (De of è of P of é of Bernard Germain De Lac) rearrange whale purpose classification, change finback park to need whale family (Balaenoptiidae) beard whale is belonged to (Balaenoptera) the following, and its belong to a name originally (Balaena) criterion reservation of whale of You Gong head, become monotype to belong to.
Finback belongs to the division that need whale, with the division is heterogeneous still have whale of whale of humpback, blue whale, cloth family name, a place of strategic importance and small beard whale. In needing whale division to be in early when new generation metaphase come out from the dissension in division of purpose of other Xu Jingya. But until uptodate till, the member that still has no a scientist to be able to excogitate this division is the species that when breaking up to differ. In Beijing University West and north Pacific maritime space, the case that now and then can blue whale follows finback cross appears.
Till 2006, the finback subspecies that the mankind discovers has 2: It is boreal finback (B. P. Physalus (Linnaeus 1758) , the maritime space that West of haunt Beijing University takes; Another subspecies is antarctic finback (B. P. Quoyi (Fischer 1829) , vast sea area is put on the ice south haunt. A lot of experts think the finback of maritime space of haunt north Pacific Ocean will become the subspecies of the 3rd finback. Place of uptodate mankind knows, these 3 finback a group of things with common features group appear very less confuse the case that make.
