In fact, however,buffalo can probably be traced back by way of one or more of the Romance languages, such as Portuguese, Spanish, or Italian, through Vulgar Latin and Latin and ultimately to the Greek wordboubalos, meaning "an antelope or a buffalo.” The buffalo referred to by the Greek and Latin words was, of course, not the American one but rather an Old World mammal, such as the water buffalo of southern Asia.Applied to the North American mammal,buffalo is in fact a misnomer, bison being the preferred term. As far as everyday usage is concerned, however,buffalo, first recorded for the American mammal in 1635, is older thanbison, first recorded in 1774. 野牛同西部荒原联系如此紧密以致人们很自然地认为这个名字源于美洲本地语言，就象这两个词moose 和 skunk。 然而，实际上buffalo 一词可以通过一种或更多种日耳曼语言，如葡萄牙语、西班牙语或意大利语溯源。 通过通俗拉丁语和拉丁语最终追溯到希腊词boubalos 意思是“羚羊或野牛”。 希腊语和拉丁语所指的野牛当然不是美洲野牛，而是东半球的一种哺乳动物，如南亚水牛。就北美哺乳动物来说，buffalo 实际上是用词不当， bison 才是合适的词。 然而就日常用法而言，buffalo 于1635年首次被用于记录美国哺乳动物， 比首次记录于1774年的bison 要早些 〔anteater〕Any of several tropical American mammals of the family Myrmecophagidae, which lack teeth and feed on ants and termites, especiallyMyrmecophaga tridactyla, having an elongated, narrow snout, a long, sticky tongue, and an extended, shaggy-haired tail. 食蚁兽：一种美洲热带食蚁科哺乳动物，没有牙齿，以蚂蚁和白蚁为食，尤其是三趾食蚁兽属 有长而细的鼻子，长而粘的舌头和长毛蓬松的尾巴 〔meat〕The edible flesh of animals, especially that of mammals as opposed to that of fish or poultry.（可食用的）肉：可食用肉，尤指（与鱼或家禽不同的）哺乳动物的肉〔dominant〕"Egrets, gulls and small mammals are the predominant wildlife on the island these days" (Dan McCoubrey).“白鹭、海鸥和小哺乳动物在这些年成了岛上的主要野生生物” （丹·麦克考布雷）。〔dewclaw〕A vestigial digit or claw not reaching the ground and found on the feet of certain mammals.上爪，残留趾：退化的足趾或在一些哺乳动物脚上发现的不接触地面的爪〔snare〕A trapping device, often consisting of a noose, used for capturing birds and small mammals.陷阱，罗网：一种通常包含有套索的捕捉装置，用来捕捉鸟类或小型哺乳动物〔unguligrade〕An unguligrade mammal.蹄行的哺乳动物〔marten〕Any of several principally arboreal carnivorous mammals of the genusMartes, related to the weasel, mainly inhabiting northern forests, and having a slender body, bushy tail, and soft fur. 貂：几种貂 属的主要栖居于树上的食肉哺乳动物的统称，与鼬类动物有亲缘关系，主要栖居在北部森林。体形细长，尾部毛浓密，皮毛柔软 〔blubber〕The thick layer of fat between the skin and the muscle layers of whales and other marine mammals, from which an oil is obtained.鲸脂：鲸和其它海洋哺乳动物的表皮层肌肉层之间的厚层，含有油脂〔boar〕The adult male of any of several mammals, such as the beaver, raccoon, or guinea pig.雄性动物：雄哺乳动物，如海狸、浣熊、豚鼠等〔elephant〕Either of two very large herbivorous mammals,Elephas maximus of south-central Asia or Loxodonta africana of Africa, having thick, almost hairless skin, a long, flexible, prehensile trunk, upper incisors forming long, curved tusks of ivory, and, in the African species, large, fan-shaped ears. 象：两种巨大的食草哺乳动物，中南亚的象属 或者非洲的 非洲象属 中的一种，皮肤坚厚，无毛，长有一条长的柔韧的可以卷曲的鼻子，上颚二门齿发展为长而弯的象牙。非洲象属有巨大的扇形状的耳朵 〔flying〕The bat is a flying mammal.蝙蝠是会飞的哺乳动物〔pinniped〕A mammal of the suborder Pinnipedia.鳍脚亚目哺乳动物〔placenta〕A membranous vascular organ that develops in female mammals during pregnancy, lining the uterine wall and partially enveloping the fetus, to which it is attached by the umbilical cord.
