Yangtze River-dolphin

The Yangtze river-dolphin of China, or ji as it is called locally, was first described in scientific journals only 80 years ago.

In 1979, ji was classified as endangered.
In August 2007, it was officially declared extinct.

The Yangtze river-dolphin had a stocky body about one and a half metres long. It had tiny eyes, and reasonable eyesight. Its long, narrow slightly upturned beak was like that of other river-dolphins. It appeared to be a dark blue-grey on its back and greyish white on its stomach. It had a triangular dorsal fin, and its flippers were broad and rather rounded.

Baiji were most active from early evening to early morning, but also hunted fish ring the day. A very shy animal, it was difficult to approach, so sightings of it were very rare. They were apparently often alone or in groups of up to six, generally in places where streams join the main river, especially around shallow sand banks.

Sometimes, when it was very quiet, the ji's blow could be heard, sounding a little like a sneeze.

In 1975, China declared the Baiji a 'National Treasure' and began conservation and protection of the mammal. This had little success because of heavy boat traffic, fishing, and instrial development, including the construction of the world's largest dam, the Three Gorges dam. A lake in Hubei province was made into a reserve, with the aim of moving the animals there to better protect them. However, it was too late, and no ji were found despite an intense search.

The Yangtze is one of the world's busiest rivers in the world's most populated country.

白鰭豚也稱為白暨豚、白鰭，是一種淡水鯨類白鱀豚科動物，僅產於中國長江中下流域，具長吻，身體呈紡錘形，全身皮膚裸露無毛，喜歡群居，性情溫順謹慎，視聽器官嚴重退化，聲納系統特別靈敏。白鰭豚是恆溫動物，用肺呼吸，被譽為「水中的大熊貓」。至20世紀由於種種原因使其種群數量減少，2002年估計已不足50頭，白鰭豚不僅被列為國家一級野生保護動物，也是世界12種最瀕危動物之一。2007年8月8日，《皇家協會生物信箋》期刊內發表報告，正式公布白鰭豚功能性滅絕。

⑧ 白鰭豚英文簡介

白鰭豚（bái qí tún），在長江里大約生活了2500萬年的白暨豚，是中新世及上新世延存至今的古老孑遺生物。白暨豚是鯨類家族中小個體成員，是世界上現有5種淡水豚(拉河豚、亞河豚、恆河豚、印河豚、白暨豚)中存活頭數最少的一種。由於數量奇少，白暨豚不僅被列為中國一級保護動物，也是世界12種最瀕危動物之一。原屬淡水豚科，20世紀70年代末，根據中國科學家周開亞教授的建議，單獨設立了白暨豚科。 鯨目白暨豚科白暨豚屬的唯一種。

白鰭豚的體形呈紡錘形，身長約2-2.5米左右，體重可達200千克以上。嘴部又長又細，背呈淺灰色或藍色，腹面為純白色，背鰭形如一個小三角，胸鰭宛如兩只手掌，尾鰭扁平，中間分叉，善於游水，時速可達80千米左右。由於長期生活在渾濁的江水中，白暨豚的視聽器官已經退化。它眼小如瞎子，耳孔似針眼，位於雙眼後下方。但大腦特別發達，聲納系統極為靈敏，頭部還有一種超聲波功能，能將江面上幾萬米范圍內的聲響迅速傳入腦中。一旦遇上緊急情況，便立刻潛水躲避。白暨豚耐寒，體溫通常在36℃左右。
編輯本段分布范圍
白鰭豚主要生活在長江中下游及與其連通的洞庭湖、鄱陽湖、錢塘江等水域中，通常成對或10餘頭在一起，喜在水深流急處活動。現有數量稀少，20年前的估計只有300頭左右，當時就已面臨滅絕的危險。
編輯本段生活習性
白鰭豚喜歡群居，尤其在春天交配季節，集群行為就更明顯。每群一般2-16頭。其活動范圍廣，但對水溫條件要求較高，經常在一個固定區域停留一段時間，待水溫條件發生改變後，又遷入另一地域。以魚類為食。
白鰭豚喜歡生活在江河的深水區，很少靠近岸邊和船隻，但它時常游弋至淺水區，追逐魚蝦充飢。它的吻寬細長，上下頜長有130多枚圓錐形的同型齒，可它卻懶得咀嚼，只管張口吞下魚食，消化能力很強。白暨豚往往成對或三五成群一起活動，但人們很少有機會看到它，只有在它露出水面呼吸時才能瞥見一眼。
白鰭豚分布在長江中下游幹流的湖北枝城至長江口約1600千米的江段內，以魚為食，喜結群活動，小群約2～3頭，大群約9～16頭。白暨豚是用肺呼吸的水生哺乳動物，每次呼吸時，頭頂及呼吸孔先浮出水面，接著露出背部和低三角形的背鰭，出水呼吸時間約1-2秒鍾，潛水時間每次約20秒，長潛時可達200秒。成熟個體最大體長，雌性2.5米，雄性2.3米，體重100～150千克，有恆定體溫，總是在36攝氏度左右。
編輯本段繁殖習性
白鰭豚兩年繁殖一次，每胎1仔，出生時體長80厘米左右。新生幼體體色略深.成年白暨豚一般背面呈淺青灰色，腹面呈潔白色，在陽光的照耀下尤其光亮。水平伸展的鰭肢和尾鰭上下兩面分別與背面和腹面同色，這樣的顏色分布恰好與環境顏色相符。當由水面向下看時，背部的青灰色和江水混為一體很難分辨；當由水底向上看時，白色的腹部和水面反射的強光顏色相近也很難被發現。這使得白鰭豚在逃避敵害、接近獵物時，有了天然的隱蔽屏障。白暨豚壽命可達30多年，雌獸一般在6歲達到性成熟，雄獸為4歲。成年白暨豚每年發情兩次，分別在3月至5月，8月至10月。孕期為10至11個月，一胎一仔，偶有兩仔。野生狀態下，成年白鰭豚雌雄比例為1：1，但雌獸懷孕率一般僅為30％，自然繁殖率很低。
每年的冬末春初是白鰭豚的交配期，母豚妊娠期長達1年左右，因此產仔大多在來年的春季。出生後的小白鰭豚靠母親的乳汁喂養，直到五六歲才算成熟；一般壽命30年。
編輯本段身體結構
白鰭豚是食肉動物，口中約有130個尖銳牙齒，為同型齒。常在晨昏時游向岸邊淺水處進行捕食，一般以整條吞食體長小於6.5厘米的淡水魚類為主，也吃少量的水生植物和昆蟲。呼吸時，頭部先出水，然後全部露出水面，在水面游動2米後，再入水中。白鰭豚的視力幾乎為零，依靠回聲定位了解環境變化的情況，在生物學、仿生學和生理學等方面具有廣泛的科研價值。但白鰭豚生性膽小，很容易受到驚嚇，一般都遠離船隻，很難接近，加之其種群數量很少，活動區域廣闊，所以在野生狀態下對白鰭豚的研究十分有限。
白鰭豚皮膚光滑細膩，富有一種特殊的彈性，原理與競賽式游泳衣著中使用具有彈性的尼龍織料相同，能夠減少在水中快速游動時身軀周圍產生的湍流。它的尾鰭扁平地分為兩叉，兩邊的胸鰭呈扁平的手掌狀，背鰭呈三角形。這四鰭給白鰭豚提供了優良的水中游動時方向與平衡的控制力，再加上光滑高彈性的皮膚與流線型的身軀，白鰭豚在逃避危險的情況下可達每小時60千米的游速。平常它保持著每小時10至15千米的游速。
白鰭豚長期生存於長江的濁水中，所以它的視覺和聽覺均退化嚴重，在水中主要以發射聲納接收信號來識別物體。白暨豚的上呼吸道有著三對獨特的氣囊與一個形似鵝頭的喉嚨，但是因為生存於水中靠水發音，所以並沒有陸地動物在空氣中發音所需要的聲帶。用特製的水聽器，可以聽到白暨豚發出的「的答」「嘎嘎」等數十種不同的聲音。白暨豚發出的聲音常為兩聲一對，發出聲音後會安靜的等待著回聲，從而辨出自己與產生回聲的阻礙的距離和大小，並且考慮是否游向目標。它又會在收到回聲後的不久發出新的一對聲音，稍候又安靜一陣等待回聲。第二次回聲收到後，它便可以分析出目標游動的方向與速度，白暨豚就是這樣如人造聲納般的做回聲定位。用這獨特的聲納系統，它時常還可以在江底的淤泥中捕捉食物，也可以發出人耳聽不見的高頻率音波，與十多千米外的同伴聯系。
白暨豚的大腦表面積要比海豚的大，大腦的重量約占總體量的0.5%，其中平均一隻重95千克的雄豚，大腦重470克。這等重量已接近大猩猩與黑猩猩的大腦重量，甚至某些學者認為白暨豚比長臂猿和黑猩猩更聰明。

Dolphin (bái qí tún), about living in the Yangtze River in the years 2500 and the white dolphin, is the Miocene and Pliocene extension has kept the ancient relict biological. White whales and dolphins are small and medium-sized indivial family members, is the world's available fresh water dolphin 5 (La globefish, Asia globefish, Platanistidae India globefish, and the white dolphin), the first to survive for at least a few. As the number of odd little white dolphin and not only China is listed as a protected species, the world's 12 most endangered animals. River dolphin origin, age 70 at the end of the 20th century, according to Chinese scientists, Professor Zhou Kaiya's proposal to set up a separate white dolphin and Branch. Mejiro whale and dolphin and the white section is the only species of dolphin.

The dolphin was spindle shape, is about 2-2.5 meters and weighing up to 200 kg and above. Long and thin mouth, back Light gray or blue, pure white for the ventral, dorsal fin-shaped as a triangle, two pectoral fin like the palm of your hand, flat tail fin in the middle fork, good at swimming, the maximum speed of 80 km around . Due to the long-term living in the muddy river, the white dolphin and audio-visual organs have been degraded. Small as it is blind eye, the eye of a needle like ears, eyes at the bottom of the post. However, the brain developed, thus, extremely sensitive sonar system, there is a head ultrasound function, Jiang could face tens of thousands of meters of the rapid introction of sound mind. In the event of an emergency, they immediately dive to escape. White dolphin and cold, the temperature is usually around 36 ℃.
Edit this paragraph distribution
The main dolphin living in the middle and lower reaches of the Yangtze River and Dongting Lake and its connected, Poyang Lake, Qiantang River waters, etc., usually in pairs or more than 10 heads together and happy with the current depth of radical activities of the Department. Scarce number of available 20 years ago, estimates that only about 300, at the time was facing extinction.
Edit this paragraph living habits
Dolphin like gregarious, especially in the spring mating season, is even more obvious acts of the cluster. Each group of 2-16 in the first general. Its wide range of activities, but the higher water temperature conditions, often in the region remain a fixed period of time, the water temperature conditions to be changed, and moved to another area. To fish for food.
Like the river dolphin living in the Sham Shui Po District, near the shore and small boats, but it is always around to shallow waters, chasing fish to eat. Its wide kiss slender, long upper and lower 130 more than the same type of conical teeth, it may be too lazy to chew, just swallow the mouth fresh fish, a strong ability to digest. White dolphin and often in pairs or small groups together, but rarely have the chance to see it, it only exposed the surface to breathe in order to catch a glimpse of a time.
Dolphin in the middle and lower reaches of the Yangtze River in Hubei Zhicheng to the main stream of the Yangtze River estuary, about 1600 kilometers of the river, to fish for food, hi clustering, a small group of about 2 to 3, the crowd of about 9 to 16. White dolphin is a lung and respiratory aquatic mammals, each breath, his head and breathing surface first hole, then his lower back and dorsal fin of the triangle, the water to breathe for about 1-2 seconds, each time diving around 20 seconds, the long latency of up to 200 seconds. The most mature indivial body length, 2.5 m female, male 2.3 meters and weighing 100 to 150 kilograms, there is a constant body temperature, always around 36 degrees Celsius.
Edit this paragraph breeding habits
Dolphin breeding first two years, Aberdeen 1 per child, born about 80 cm length. Newborn larvae deep color slightly. Dolphin and the general alt white on the back of Green Light gray, white ventral was clean, the sun's shining especially bright. The level of the extended flipper and tail up and down with both sides of the same color on the back and ventral, so that the distribution of color exactly match the color and the environment. When looking down from the surface, the back of the green and gray of the river is mixing it is difficult to distinguish; from the bottom to the point of view when, a white belly and the light reflected from the surface color is also similar to those found to be very difficult. This allows the dolphin to avoid Di Hai, close to the game, with the hidden natural barriers. White dolphin and up to 30 years of life, in general Cishou 6-year-old to reach sexual maturity, Xiongshou 4-year-old. Alt white dolphin and estrus twice a year, in March to May and August to October. Pregnancy for 10-11 months, a one-child class, sometimes two earners. Wild state, an alt male and female ratio of 1:1 dolphin, but Cishou pregnancy rate was only 30% of the normal, natural reproction rate is very low.
Dongmochunchu annual dolphin is the mating season, the mother dolphin pregnancy for up to 1 year or so, so most of the litter in the spring of next year. After the birth of small dolphin feeding by the mother's milk until five or six-year-old is mature; general life expectancy of 30 years.
Editor of the physical structure of the paragraph
Dolphin is predators, population about 130 sharp teeth, tooth for the same type. Often in the twilight tour shore shallows when Predation for the general to swallow the entire length of less than 6.5 cm of fresh water fish-based, but also eat small amounts of aquatic plants and insects. Breathe, the water head first, and then exposed all of the water, swimming in the water 2 meters, the water re-entry. Dolphin's vision is almost zero, to rely on echolocation to understand environmental changes in biology, physiology and bionics, and so on a wide range of scientific research value. But the dolphin timid nature, are susceptible to shock, usually away from the vessel, it is difficult to close, combined with its small population, vast regional activities, so in a state of wild dolphin research is very limited.
Dolphin skin smooth and delicate, full of a special kind of flexibility with the principle of competition-style bathing suit with the use of flexible nylon weave the same material, to rece the fast swimming in the water when the turbulence generated around the body. Its flat tail fin to be divided into two forks, on both sides of the pectoral fin was like the palm of your hand flat, triangular dorsal fin. This four-fin dolphin to provide excellent swimming in the water when the direction of balance and control, combined with high flexibility of the skin smooth and streamlined body, the dolphin to avoid dangerous situations, up to 60 km per hour speed of travel . It usually maintains a 10-15 km per hour, the travel speed.
Long-term survival of the Yangtze River dolphin in the Cho-shui, it's visual and hearing are severely degraded, the water in the main reception to launch sonar signals to identify objects. White dolphin and the upper respiratory tract has three unique shape of a balloon with a goose head of the throat, but to survive in the water by water sounds, and there is no land animal in the air pronunciation of the vocal cords needed. With a special hydrophone, you can hear the white dolphin and issued "A" "quack" and dozens of different voices. White dolphin and the voice of regular twice for a pair of issuing a quiet voice will be waiting for the echo, which detected the echo of their own and have hindered the distance and size, and to consider whether travel to the goal. It will echo the receipt issued shortly after a pair of new voices, and wait quietly for a while waiting for the echo. The second received echo, it will be able to analyze the goal of swimming in the direction and speed, and white dolphin is one such man-made, such as sonar-like echolocation to do. This unique use of the sonar system, which can from time to time in the mud at the end of Jiang's capture in food, can not issue a human face value of the high-frequency sound waves, with more than 10 km outside the peer contact.
White dolphin and the surface area of the brain than the dolphin, the weight of the brain accounts for about 0.5 percent of overall volume, of which an average weight 95 kg male dolphin, brain weight 470 grams. This is close to the weight of gorilla and chimpanzee brain weight, and even some scholars believe that white dolphins and chimpanzees and gibbons than smarter.
