鳞甲目的穿山甲 食蚁兽是贫齿目的,这一目有3科,食蚁兽科,树懒科,犰狳科

A pangolin (pronounced /ˈpæŋɡəlɪn/), also scaly anteater or tenggiling, is a mammal of the order Pholidota. There is only one extant family (Manidae) and one genus (Manis) of pangolins, comprising eight species. There are also a number of extinct taxa. Pangolins have large keratin scales covering their skin and are the only mammals with this adaptation. They are found in tropical regions of Africa and Asia. The name "pangolin" derives from the Malay word pengguling ("something that rolls up"). Pangolins are nocturnal animals, and use their well-developed sense of smell to find insects. The long-tailed pangolin is also active by day. Pangolins spend most of the daytime sleeping, curled up into a ball.
The physical appearance of pangolins is marked by large, hardened, plate-like scales. The scales, which are soft on newborn pangolins but harden as the animal matures, are made of keratin, the same material of which human fingernails and tetrapod claws are made. The pangolin is often compared to a walking pine cone or globe artichoke. It can curl up into a ball when threatened, with its overlapping scales acting as armour and its face tucked under its tail. The scales are razor-sharp, providing extra defence. The front claws are so long that they are unsuited for walking, and so the animal walks with its fore paws curled over to protect them. Pangolins can also emit a noxious smelling acid from glands near the anus, similar to the spray of a skunk. Pangolins have short legs, with sharp claws which they use for burrowing into termite and ant mounds, as well as climbing.
The size of pangolins varies by species, ranging from 30 cm to 100 cm (12 to 39 inches). Females are generally smaller than males.
The tongues of pangolins are extremely elongated and extend into the abdominal cavity. By convergent evolution pangolins, the giant anteater, and the tube-lipped nectar bat, all have tongues which are unattached from their hyoid bone and extend past their pharynx deep into the thorax. This extension lies between the sternum and the trachea. Large pangolins can extend their tongues as much as 40 cm (16 inches), with a diameter of only 0.5 cm (1/4 inch).
In pangolins, the section of the brain that relates to problem solving is highly developed. Although their problem solving ability is primarily used to find food in obscure locations, when kept in captivity pangolins are remarkable escape artists.
Arboreal pangolins live in hollow trees, whereas the ground dwelling species dig tunnels underground, up to a depth of 3.5 m (11 feet). Pangolins are also good swimmers.

食蚁兽属贫齿目食蚁兽科穿山甲分类地位
动物界 Fauna → 脊索动物门 CHORDATA → 脊椎动物亚门 Vertebrata →
哺乳纲 Mammalia → 真兽亚纲 Tberia → 鳞甲目 Pholidota → 鳞鲤科 Manidae不是一个科的

马、羊、鹿等偶蹄类动物一般一生下来10分钟就能跑,成年动物会把它们围在中间以免被捕食者吃掉.
鳄鱼等爬行类会把蛋埋在沙里
昆虫幼虫一般有保护色或毒刺
鸡鸭等早成鸟也是生下来就会跟着妈妈跑,遇到危险妈妈会把他们藏在翅膀下
猴子等灵长类包括人,要抱在怀里几年,
猫科的哺乳期需要照看,断奶后也是跟在妈妈后面跑
几年级的题目,差不多脊椎动物门的都要哎.so complicated

蚂蚁—穿山甲,瓢虫—蚜虫,灰喜鹊—松毛虫,黄雀—螳螂,狐狸—松鼠

排除法,只能选择C

解题思路：传染病是由病原体引起的，病原体有细菌、真菌、寄生虫等致病的微生物，据此分析解答．

很多野生动物本身就携带病原体，如青蛙、蛇、穿山甲携带钩虫、旋毛虫等，病原体是指能引起传染病的有细菌、真菌、寄生虫等．
故答案为：病原

点评：
本题考点： 病原体与传染病的病因；动物在自然界中的作用．

考点点评： 很多野生动物本身就携带病原体，要少接触，但不要杀戮．

穿山甲是用舌捕食的 .
舌细长,能伸缩,带有粘性唾液,觅食时,以灵敏的嗅觉寻找蚊穴,用强健的前肢爪掘开蚁洞,将鼻吻深入洞里,用长舌舐食之.
穿山甲的食量很大,一只成年穿山甲的胃,最多可以容纳500克白蚁.据科学家观察,在250亩林地中,只要有一只成年穿山甲,白蚁就不会对森林造成危害,可见穿山甲在保护森林、堤坝,维护生态平衡、人类健康等方面都有很大的作用.

1北极熊在熊科动物家族中属于正牌的食肉动物,它们主要捕食海豹,特别是环斑海豹,此外也会捕食髯海豹、鞍纹海豹、冠海豹.除此之外,它们也捕捉海象、白鲸、海鸟、鱼类、小型哺乳动物,有时也会打扫腐肉.也是唯一主动攻击人类的熊,北极熊的攻击大多发生在夜间 2 白犀牛吃吃低草,黑犀牛吃高草,印度犀牛吃草,树叶 3 穿山甲是一种专食性动物,野性强,孤僻,对环境的适应性较差,白天匿居洞中,夜晚出洞觅食.穿山甲食性特异,专食蚁类,每天每只穿山甲需进食80-120克白蚁 4食性:刺猬为夜行性动物,傍晚前后投喂饲料和清水即可.
刺猬是杂食性动物,在野外主要靠捕食各种无脊椎动物和小型脊椎动物以及草根,果,瓜等植物为生.家庭饲养可以自配饲料,以肉类下脚,粮食及副产品,青菜等按比例配合饲养.另外,毛毛虫,甲虫,蜗牛,蚯蚓等小动物和水果也可喂养.以树叶,青草等.夜行性.食物以昆虫为主,也吃小鼠,鸟卵,小蛇等.每年繁殖1～2次,妊娠期35～37天,每胎3～6仔.初生幼仔身体粉红色,具白色软刺,眼未睁开,耳孔也未通,身体尚不能卷缩.刺猬有冬眠习性,在北京地区10月开始入眠,来年3月底出眠,入眠前贮存大量皮下脂肪,可达体重的五分之一 如将野外刚捕来的刺猬进行人工驯养,动物性饲料要占食物的80%,以后可以慢慢减少,增加植物性食物的比重.投喂的饲料必须新鲜,干净,瓜果蔬菜要洗净后投喂.如从市场买来的瓜菜还要先放在水池内浸泡1 小时,再洗净配喂,以防农药中毒.同时,饲料要品种多样化,饲料单一会引起刺猬间相互咬斗和拒食 5 其实黄鼠狼爱吃的是鼠.它还是一个捕鼠能手呢.据统计,一只黄鼠狼一年能消灭三四百只鼠类.一旦老鼠被它咬住,几口就可下肚.如果寻找鼠窝,它可以掘开鼠洞,整窝消灭.以每年每只鼠吃掉1公斤粮食计算,一只黄鼠狼可以从鼠口里夺回三四百公斤粮食.所以黄鼠狼决不是什么偷鸡贼,6 蓝鲸以浮游生物为食,主食磷虾.一头蓝鲸每天消耗2～4t食物 7 东非草原上常见的金合欢树.这种树的叶子,则是长颈鹿最喜欢吃的食物 8 腊肠树：原生在非洲水边,果实像腊肠,河马喜欢吃 楼主给我最佳啊

答案一：蛇
因为其他三个动物都有“甲壳”,蛇没有.
答案二：蜗牛
蛇、乌龟、穿山甲都是脊椎动物,而蜗牛不是.另外,只有蜗牛是吃素的.

白兔的眼睛为什么是红的?是血液的颜色 穿山甲是用什么捕食的?舌头

很简单,因为穿山甲是胎生的...而且是恒温动物!

A、狗的短毛和狗的卷毛，是两种性状，不是相对性状，A不正确；
B、羊和兔是两个物种，因此羊的黑毛和兔的白毛，不是相对性状，B不正确；
C、穿山甲和鹅是两个物种，因此穿山甲的爬行和鹅的游泳，不是相对性状，C不正确；
D、狐的长尾和短尾是同一性状的不同表现形式，是相对性状，D正确．
故选：D．

刺猬、豪猪和针鼹长刺,穿山甲和犰狳身披鳞片,这个问题是你的误解,人是哺乳动物,那人为什么大部分皮肤是裸露的?没人说哺乳动物应该体表被毛的,只是大部分体表被毛,人体表的毛发退化,而鲸的体表的毛发全部退化,而刺猬、豪猪和针鼹是毛发特化为针刺,穿山甲和犰狳是角质层厚化增生形成了鳞甲,这些都是不同动物为了习惯不同环境而形成的特殊结构,
