6/23`这种狼仅仅只会长到3英尺高.北极狼吃驼鹿、鱼类、北极熊和兔子。它们用林子里灰色、绿色和褐色作为掩护，北极狼有着一层厚厚毛，它们牙齿非常尖利，这有利于它们捕杀猎物。生活在从加拿大拉布拉多地域到英国哥伦比亚地域，它们不迁徙，也不冬眠。不过因为因为人类采伐树木、污染和垃圾，它们失去了它们居住地方。每年最少有196只北极狼死去。Thisisonlythewolf'sheadtojust3feethigh.Arcticwolveseatmoose,fish,polarbearsandrabbits.Theyusethewoodsofgray,greenandbrownasacover,theArcticwolfhasathicklayerofhair,theirteethareverysharp,whichhelpsthemtokilltheirprey.LivingintheLabradorregionfromCanadatotheBritisharea,theydonotmigrateorhibernate.However,duetohumanharvesting,pollutionandwaste,theyhavelosttheirplacetolive.Everyyearatleast196died.7/238/23Alligator扬子鳄9/23Madeitanational-levelprotectedanimals,alligatorbodyabout2meters.Backdarkbrown,somedarkgreen,theAlligatorhasbeenendangered.Itisthicklimbs,tail,skills,andtheirlong-evenmorethantheheadandbodylengthcombined.Peoplehavealligatorknownasthe"livingfossil"becauseitwastwobillionyearsago,thedinosaureratoexist.我国特产动物，已频临灭绝。我国已经把它列为国家一级保护动物。扬子鳄身长约2米。背部暗褐色，有呈深绿色。它四肢粗壮，尾巴专长，其长甚至超出了头和身体长度总和。人们把扬子鳄称为“活化石”，是因为它在两亿年前恐龙时代就存在了。10/2311/23thewhitedolphin12/2313/2314/23WhitedophinisaboutlivingintheYangtzeRiverfor250millionyearsintheMioceneandPlioceneextension,ithaskepttheancientrelictbiological.Whitedolphinsaresmallandmedium-sizedindividualfamilymembers.Theyareoneoftheworld'savailablefreshwater5dolphins(Laglobefish,Asiaglobefish,PlatanistidaeIndiaglobefish,andthewhitedolphin),tosurviveatleastquantity.AsthenumberofoddlittlewhitedolphinisnotonlylistedasaprotectedspeciesinChina,butalsointheworld's12mostendangeredanimals.

白鳍豚在长江里大约生活了2500万年白暨豚，是中新世及上新世延存至今古老孑遗生物。白暨豚是鲸类家族中小个体组员，是世界上现有5种淡水豚(拉河豚、亚河豚、恒河豚、印河豚、白暨豚)中存活头数最少一个。因为数量奇少，白暨豚不但被列为中国一级保护动物，也是世界12种最濒危动物之一。15/23Red-crownedcrane16/2317/2318/23Red-crownedcraneisdistributedintheNenjiangRiver,SonghuaRiverandWusuliRiver,thelowerreachestheYangtzeRivertogothroughwinter,inHebei,Shandongtriptothebirds,inTaiwan,theyareoccasionallyseen.
