PANDA

Striking black-and-white bear with black fur around the eyes,on the ears,on all four legs,and across the back from shoulder to shoulder.Sometimes the black fur is replaced with reddish black or brownish fur.Unusually,it has six digits on each front foot,with the sixth digit actually an extension of the sesamoid bone and serving as an opposable thumb,thus giving the panda additional dexterity.This stocky bear reaches about 5.5–6 ft (1.7–1.8 m) in body length and weighs about 175–280 lb (80–125 kg),with the females about 10–15 percent lighter than the males.

Primarily eat bamboo,including the leaves,stems,and shoots.They are the most vegetarian of the bears,eating little other than bamboo.They have flattened molars and a specialized digestive system to handle the tough plant material.

Common Name Elephant ; Elephant (Fr); Elefante (Sp)

Scientific Name Elephas maximus (southern Asia),Loxodonta africana (Africa)

Location Africa,Asia

These large and magnificent creatures need a lot of food and freedom if they are to survive.They wander in small to large herds over sometimes incredibly large areas while consuming up to several hundred kilogrammes of plant matter in a single day.

Elephants,in fact,place such great demands on their own environment that in order to survive,it will frequently bring them into conflict with man who is competing for many of these same,often scarce resources.

On the ground on two continents

In all,the problems facing elephants in Asia and Africa are varied and complex.To this end,WWF is involved in their conservation through 2 key programmes which address local key issues,the realities faced on the ground,and this ever present conflict with man.These programmes are:

Asian Rhinos and Elephants Action Strategy (AREAS):This ambitious Programme brings together cutting edge conservation biology with trade monitoring,socio-economic analysis,and policy advocacy,promising new hope for dwindling populations of these threatened pachyderms.

WWF African Elephant Programme:The Programme aims to conserve forest and savanna elephant populations across Africa by supporting projects that improve protection and management,build capacity within range states,mitigate human-elephant conflict and reduce illegal trade.

Physical Description

Species Description

Elephants are identified by their massive bodies and their trunk,which is used to pick a variety of objects,including food.The head is large in relation to the rest of the body and the African species is noted for its very large ears.Hair is sparse.

The Asian elephant has four hooves (occasionally five) on the hind foot and five on the forefoot,and the African elephant has three on the hind foot and five on the forefoot.

Size

Living members of the order Proboscidea have a maximum height of nearly 400 cm and a weight of up to 7,500 kg.

Habitat

Biogeographic realm

Indo-Malayan,Afrotropical

Geographical Location

Africa,Asia

The giant panda has a very distinctive black-and-white coat,and adults measure around 1.5m long and around 75cm tall at the shoulder.Males can weigh up to 115 kg (253 pounds).Females are generally smaller than males,and can occasionally weigh up to 100 kg (220 pounds).Giant pandas live in mountainous regions,such as Sichuan,Gansu,Shaanxi,and Tibet.While the Chinese dragon has been historically a national emblem for China,since the latter half of the 20th century,the panda has also become an informal national emblem for China,and its image is found on many Chinese gold coins.

Despite being taxonomically a carnivore,the panda has a diet that is primarily herbivorous,which almost exclusively consists of bamboo.This is an evolutionarily recent adaptation,or perhaps just a very awkward one; pandas lack the proper enzymes to digest bamboo efficiently,and thus derive little energy and little protein from it.

While primarily herbivorus,the panda still retains decidedly ursine teeth,and will readily eat meat,fish,and eggs when available,but their sluggish speeds,a consequence of their mainly bamboo diet,ensure that these more energy-rich foods are seldom available to them outside of captivity.In captivity,zoos typically maintain the pandas' bamboo diet,though some will provide specially formulated biscuits or other dietary supplements.

Unlike most bears,but like most subtropical mammals,the giant panda does not hibernate.

For many decades the precise taxonomic classification of the panda was under debate as both the giant panda and the distantly related red panda share characteristics of both bears and raccoons.However,genetic testing suggests that giant pandas are true bears and part of the Ursidae family,though they differentiated early in history from the main ursine stock.The giant panda's closest bear relative is the Spectacled Bear of South America.(Disagreement remains about whether or not the red panda belongs in Ursidae; the raccoon family,Procyonidae; or in its own family,Ailuridae.)

Giant pandas are an endangered species,threatened by continued habitat loss and by a very low birthrate,both in the wild and in captivity.Poaching is uncommon; killing a panda was punishable in China by death until a 1997 law changed the penalty to 20 years imprisonment.

The giant panda has an unusual paw,with a "thumb" and five fingers; the "thumb" is actually a modified sesamoid bone,which helps the panda to hold the bamboo while eating.Stephen Jay Gould wrote an essay about this,then used the title The Panda's Thumb for a book of essays concerned with evolution and intelligent design.The giant panda has a short tail,approximately 15 cm long.

The giant panda has long been a favorite of the public,at least partly on account of the fact that the species has an appealing baby-like cuteness that makes it seem to resemble a living teddy bear.The fact that it is usually depicted reclining peacefully eating bamboo,as opposed to hunting,also adds to its image of innocence.Though the giant panda is often assumed docile because of their cuteness,they have been known to attack humans,usually assumed to be out of irritation rather than predatory behavior.

Giant pandas can usually live to be 20-30 years old while living in captivity.

Until recently,scientists thought giant pandas spent most of their lives alone,with males and females meeting only during the breeding season.Recent studies paint a different picture,in which small groups of pandas share a large territory and sometimes meet outside the breeding season.

问题3：珍稀动物作文怎么写[生物科目]

丹顶鹤每年要在繁殖地和越冬地之间进行迁徙,只有在日本北海道是当地的留鸟,不进行迁徙,这可能与冬季当地人有组织的投喂食物,食物来源充足有关.丹顶鹤的栖息地是沼泽和沼泽化的草甸,食物主要是浅水的鱼虾、软体动物和某些植物根茎,以季节不同而有所变化.丹顶鹤成鸟每年换羽两次,春季换成夏羽,秋季换成冬羽,属于完全换羽,会暂时失去飞行能力.丹顶鹤的鸣声非常嘹亮,作为明确领地的信号,也是发情期交流的重要方式.丹顶鹤属于单配制鸟,若无特殊情况可维持一生.每年的繁殖期从3月开始,持续6个月,到9月结束.它们在浅水处或有水湿地上营巢,巢材多是芦苇等禾本科植物.丹顶鹤每年产一窝卵,产卵一般2~4枚.孵卵由雌雄鸟轮流进行,孵化期31~32天.雏鸟属早成雏.

丹顶鹤为杂食性.春季以草籽及作物种子为食,夏季食物教杂,动物性食物较多,主要动物性食物有小型鱼类、甲壳类、螺类、昆虫及其幼虫等,也食蛙类和小型鼠类,植物型食物有芦苇的嫩芽和野草种子等.

浣熊原产自北美洲,因其进食前要将食物在水中浣洗,故名浣熊.浣熊眼睛周围为黑色,尾部有深浅交错的圆环,皮毛的大部分为灰色,也有部分为棕色和黑色.也有罕见的白化种.体长65到75cm,尾长约25cm.浣熊为杂食动物,食物有浆果、昆虫、鸟卵和其它小动物.生活在都市近郊的浣熊常会潜入人类住处偷窃食物,加上眼睛周遭的黑色条纹特征,因此常被称为"食物小偷".

大部分生活在加拿大,晚上十二点后出门,加拿大人称之为神秘小偷.

问题4：中国的濒危动物资料

1.古朴国宝：大熊猫

大熊猫是一种以食竹为主的食肉目动物,不仅集珍稀、濒危、特产于一身,而且非常古老,有“活化石”之称.与其同时代的古动物剑齿虎、猛犸象、巨貘等均已因冰川的侵袭而灭绝,惟有大熊猫因隐退山谷而遗存下来.现仅分布于中国四川、陕西、甘肃约40个县境内的群山叠翠的竹林中,过着与世无争的隐居生活.

2.仰鼻蓝面：金丝猴

中国金丝猴包括川、滇、黔三种,大家比较熟悉的当属川金丝猴.川金丝猴,分布于四川、陕西、湖北及甘肃,深居山林,结群生活.背覆金丝“披风”,攀树跳跃、腾挪如飞.金丝猴刚被命名时,因其仰鼻金发,使动物学家爱德华先生联想起欧洲十字军司令的翘鼻金发的夫人洛克安娜,于是,他便用这个美人之名命名了金丝猴—— Rhinpitheius roxellanae

3.长江奇兽：白鳍豚

白鳍豚为中国长江中下游的特有水兽,全球豚类有70多种,淡水仅5种,中国仅此一种淡水鲸,分布狭窄,比大熊猫更古老、更稀少.白鳍豚体态娇美、皮肤滑腻、长吻似剑、身呈纺锤.眼小如豆、耳小像针,上下颌密布小牙130多颗,头顶左上方有一圆形鼻孔,每隔20秒出水换一次气,虽然视听能力欠佳,但其声纳系统发对超声波的回声定位能力可使它与在十几公里外的同伴取得联系.

4.中华之魂：华南虎

华南虎的英文为“中国虎”,是我国特有亚种,原为中国分布最广、数量最多、体型较小,但资格最老的一个虎种.全球的虎仅有一种,均产于亚洲,上个世纪尚有8个亚种：孟加拉虎、东北虎、爪哇虎、华南虎、里海虎、巴厘虎、苏门达腊虎,但后三个亚种相继灭绝,中国的新疆虎（尚未搞清属于哪个亚种）是在20世纪初灭绝的.

5. 东方之珠：朱鹮

要问中国最珍稀的鸟是什么,那朱鹮应当名列前茅.这种被动物学家誉为“东方明珠”的美丽涉禽是一种人们一度认为已经灭绝的鸟类,它们原是东亚地区的特产鸟类,仅在中国、朝鲜、日本及俄罗斯有分布,但二十世纪六十年代后都失去了踪影.难道朱鹮真的消失了吗?七十年代后期,中国鸟类学家开始寻找朱鹮,1981年终于在陕西洋县姚家沟发现2窝共7只朱鹮,轰动了世界.

6.堪称国鸟：褐马鸡

褐马鸡是一种产于中国山西庞泉沟、河北小五台山及北京门头沟的珍禽,因耳部由两个雪白的耳羽,好似长角,或有人称之为角鸡或耳鸡.尾羽上翘后,披散垂下,如同马尾,故名马鸡,马鸡属共有4种,均产于中国,既藏马鸡、白马鸡、蓝马鸡和褐马鸡.许多动物学家建议,应把褐马鸡定为中国国鸟.目前,褐马鸡为国际自然保护联盟IUCN红皮书“濒危”级,国家一级保护动物.

7.孑遗物种：扬子鳄

扬子鳄是中国唯一的鳄种.全球鳄鱼共有25种,中国只有湾鳄和扬子鳄.但是作为体型最大的鳄（10米长）,湾鳄早已在几百年前灭绝了,而扬子鳄现为我国特有,也是从远古北方仅存的唯一分布在温带的孑遗种类.

8.高原神鸟：黑颈鹤

黑颈鹤是世界上唯一一种高原鹤类,是藏族人民心目中神圣的大鸟,也是世界十五鹤中被最晚记录到的一种鹤,它是俄国探险家普热尔瓦尔斯基于1876年在中国青海湖发现的.黑颈鹤夏季在西藏繁殖,冬季迁至云贵越冬,少数还飞越喜马拉雅山至不丹越冬.

9.雪域喋血：藏羚羊

藏羚羊,近年极受世人瞩目,主要原因是由于1980年以来西方时装界对“藏羚绒披肩”即“沙图什”的消费需求而刺激了偷猎者的谋财害命,另外,一些采金者也在对其肆意杀戮,致使生活在生命极限的高寒地区的藏羚羊正以一年近万只的速度减少.为打击盗猎,这几年青海、新疆、西藏的反盗猎力量林业公安一直在为保卫藏羚羊等野生动物而战斗,其中的佼佼者即“野牦牛队”,他们已经有两位英雄为此献身.

10.失而复得：四不象

“四不象”为麋鹿的俗名,它是做为中国特有的湿地鹿类,曾于1900年在中国本土灭绝的,幸有少量存于欧洲,经过一个世纪的养护,种群才得以恢复.麋鹿是湿地动物,由于对湿地生境的适应,而形成特殊的形态,即所谓的“四不象”,角似鹿非鹿、脸似马非马、蹄似牛非牛、尾似驴非驴.麋鹿,为国家一级保护动物,国际自然保护联盟IUCN红皮书极危级.

问题5：·有关濒危动物的保护的文章[生物科目]

濒危动物是一项珍贵的、不可替代的、可再生的自然资源,在维护生态平衡、促进经济发展、满足人民日益增长的物质和文化需求、发展对外关系、提高社会主义精神文明等方面发挥着重要作用.

一、维护生态平衡

每个物种都是生态系统中的重要一员,通过食物链的关系,物种之间起到互相依存、互相牵制的作用.一旦食物链的某一环节出现问题,整个生态系统的平衡就会受到严重影响.比如,由于无节制地猎捕蛇类,致使蛇类资源枯竭,导致森林、草原和农田鼠害在局部地区猖獗.又如,由于大量使用农药和化肥以及猎捕活体用作宠物贸易,致使食虫鸟类数量急剧减少,导致松毛虫、蝗虫等森林和农作物病虫害大面积发生.鼠害和病虫害给农林牧业造成了巨大损失,生态失衡的代价之大是无法估量的.

二、保证科学研究和教育活动的正常开展

濒危动物是科学研究的试验材料,在动物学、进化学、生态学、遗传学、现代医学、仿生学等学科领域里发挥着重要作用.如我国驯养繁殖的数万只食蟹猴和猕猴,绝大多数都被用作实验动物或用来生产抗病防病的疫苗.科研院所、大专院校、动物园以及博物馆收藏、陈列或展出濒危动物的标本,对科研教学、宣传教育、执法活动等发挥了重要作用.

三、促进经济发展,满足人民生活需要

绝大多数濒危动物都有很高的经济价值或观赏价值.

(一)药用价值.我国的传统医学就是在研究和利用野生动植物的基础上发展起来的,虎骨、豹骨、犀牛角、麝香、穿山甲片、赛加羚羊角、熊胆粉、海龟壳、蛤蚧、眼镜蛇毒、蟾酥等,是中医药不可或缺的重要原料.1993年,为配合国际社会保护虎和犀牛的努力,我国政府禁止了对犀牛角和虎骨的贸易,为此也付出了高昂的代价,直接经济损失达23亿元.

(二)食用和衣用价值.我们的祖先在“茹毛饮血”的时代就是依靠采集或猎捕野生动植物来维持生计的.即使到了20世纪的今天,许多动物依然是我们生活中常见的食用或衣用原料.如鹿肉、黄羊肉、紫貂皮、黄鼬皮、豹猫皮、水獭皮、藏羚羊绒、燕窝、飞龙、鳄鱼肉、鳄鱼皮、鸵肉、蛇干、蛇皮、蛇粉等.单就蛇类而言,1997年我国利用各类活蛇约9000吨,价值就达4亿元以上.

(三)观赏价值.濒危动物具有很高的观赏价值,是动物园、森林公园、自然保护区或风景名胜区招揽游客的王牌,是马戏团表演的主角,也是部分家庭养殖观赏或许多文人墨客吟诗作画的主要对象.赴国外展出和合作研究一对大熊猫,每年至少可为国家筹集到800万元大熊猫保护基金.另外,象牙、河马牙雕刻而成的工艺品以及孔雀、鸵鸟羽毛、蝴蝶、盘羊头骨制成的装饰品,也具有很高的艺术观赏价值.

(四)外交价值.我国特产动物大熊猫、金丝猴、东北虎、朱huan等,既是世界级濒危动物,也是各国人民极为喜爱和渴望参观的珍稀动物.对外赠送或赴外展出这些动物,对提高中国知名度、发展国家间政经关系、促进文化交流、增进民间友谊、宣传我国濒危动物保护管理成就、开展濒危动物合作研究、筹集濒危动物保护经费等,可以发挥奇特的作用.

(五)娱乐狩猎价值.1998年我国批准对外狩猎了3只羚牛、23只盘羊、61只猎隼、4只白唇鹿、57只岩羊、32只藏原羚、2只北山羊、1只水鹿,共为国家筹集到濒危动物保护管理经费1170万元,还调动了当地政府和老百姓保护濒危动物的积极性,有利于解决当地的扶贫济困问题.

(六)潜在的开发价值.物种的价值,人类目前所了解到的仅仅是其极小一部分.随着科学技术的发展,各个物种的潜在价值将会逐渐被发现和认识.但是如果物种在被人们认识之前就已灭绝,就谈不上开发利用这些价值了.无疑,这对我们人类来说是极大的遗憾,对生物多样性保护来说也是一大损失.

由此可见,我们不仅要保护濒危动物,而且还要发展濒危动物资源,最终达到永续利用的目的.用一句话来概括,那就是,保护濒危动物是为了永续利用濒危动物.
