It is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, although it is still a large mammal. This rhino stands 112–145 cm (3.67–4.76 ft) high at the shoulder, with a head-and-body length of 2.36–3.18 m (7.74–10.43 ft) and a tail of 35–70 cm (14–28 in). The weight is reported to range from 500 to 1,000 kg (1,100 to 2,200 lb), averaging 700–800 kg (1,500–1,800 lb), although there is a single record of a 2,000 kg (4,400 lb) specimen. Like both African species, it has two horns; the larger is the nasal horn, typically 15–25 cm (5.9–9.8 in), while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Sumatran rhino\'s body.
Members of the species once inhabited rainforests, swamps, and cloud forests in India, Bhutan, Bangladesh, Myanmar, Laos, Thailand, Malaysia, Indonesia, and China. In historical times, they lived in southwest China, particularly in Sichuan. They are now critically endangered, with only six substantial populations in the wild: four on Sumatra, one on Borneo, and one in the Malay Peninsula. Their numbers are difficult to determine because they are solitary animals that are widely scattered across their range, but they are estimated to number fewer than 275. Survival of the Peninsular Malaysia population is in doubt, and one of the Sumatran populations may already be extinct. Total numbers today may be as low as 200. The decline in the number of Sumatran rhinoceroses is attributed primarily to poaching for their horns, which are highly valued in traditional Chinese medicine, fetching as much as US$30,000 per kg on the black market.
The Sumatran rhino is a mostly solitary animal except for courtship and offspring-rearing. It is the most vocal rhino species and also communicates through marking soil with its feet, twistingsaplings into patterns, and leaving excrement. The species is much better studied than the similarly reclusive Javan rhinoceros, in part because of a program that brought 40 Sumatran rhinos into captivity with the goal of preserving the species. The program was considered a disaster even by its initiator; most of the rhinos died and no offspring were produced for nearly 20 years, representing an even worse population decline than in the wild.
A mature Sumatran rhino stands about 120–145 cm (3.94–4.76 ft) high at the shoulder, has a body length of around 250 cm (8.2 ft) and weighs 500–800 kg (1,100–1,800 lb), though the largest individuals in zoos have been known to weigh as much as 2,000 kilograms (4,400 lb). Like the African species, it has two horns. The larger is the nasal horn, typically only 15–25 cm (5.9–9.8 in), though the longest recorded specimen was much longer at 81 cm (32 in). The posterior horn is much smaller, usually less than 10 cm (3.9 in) long, and often little more than a knob. The larger nasal horn is also known as the anterior horn; the smaller posterior horn as the frontal horn.The horns are dark grey or black in color. The males have larger horns than the females, though the species is not otherwise sexually dimorphic. The Sumatran rhino lives an estimated 30–45 years in the wild, while the record time in captivity is a female D. lasiotis which lived for 32 years and 8 months before dying in the London Zoo in 1900.
Two thick folds of skin encircle the body behind the front legs and before the hind legs. The rhino has a smaller fold of skin around its neck. The skin itself is thin, 10–16 mm (0.39–0.63 in), and in the wild, the rhino appears to have no subcutaneous fat. Hair can range from dense (the most dense hair in young calves) to scarce, and is usually a reddish-brown. In the wild, this hair is hard to observe because the rhinos are often covered in mud. In captivity, however, the hair grows out and becomes much shaggier, likely because of less abrasion from walking through vegetation. The rhino has a patch of long hair around its ears and a thick clump of hair at the end of its tail. Like all rhinos, they have very poor vision. The Sumatran rhinoceros is fast and agile; it climbs mountains easily and comfortably traverses steep slopes and riverbanks白犀牛吃什么食物\" class=\"8528-d380-6362-acc1 colorh colorh-01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.

刺猬是杂食动物。它们主要以无脊椎动物和小型脊椎动物为食，也吃野外的草根、水果、瓜类等植物。家庭喂养可以自己准备，有肉渣、粮食及副产品、蔬菜等按比例搭配。此外，毛毛虫、甲虫、蜗牛、蚯蚓等小动物和水果也可喂养。树叶、草等都是夜间活动的。食物主要是昆虫，但也有老鼠和蔬菜。妊娠期35 ~ 37天，每个胎儿有3 ~ 6个宝宝。刚出生的婴儿都是粉红色的，有白色的刺，眼睛没有睁开，耳朵没有张开，身体也不能蜷缩。刺猬有冬眠的习惯。他们在北京10月份开始睡，明年3月底出门。在入睡前，它们会储存大量的皮下脂肪，这些脂肪可达其体重的五分之一。举个例子，如果把刚从野外抓来的刺猬进行人工驯化，动物饲料就要占到食物的80%。增加植物性食物的比例。饲料一定要新鲜干净，果蔬要洗净后再喂。比如从市场买来的瓜菜，要在池子里泡1个小时，然后洗干净，配给，防止农药中毒。同时饲料要多样化，单一的饲料会造成刺猬互相撕咬，不肯进食。事实上，黄鼠狼喜欢老鼠。他也是抓老鼠的专家。据统计，一只黄鼠狼一年能杀死三四百只老鼠。老鼠一旦被它咬到，几口就能吞下去。如果找一个鼠窝，它可以挖一个鼠洞，毁掉整个窝。以每只老鼠每年吃1斤粮食计算，一只黄鼠狼可以从老鼠嘴里拿回300斤粮食。所以，黄鼠狼绝不是偷鸡贼。6蓝鲸以浮游生物为食，主要食物是磷虾。一头蓝鲸每天消耗2 ~ 4t食物，东非草原常见7棵洋槐。这棵树的叶子是长颈鹿最喜欢的食物。8腊肠树:原产于非洲水边，果实像腊肠。河马喜欢吃它。楼主给了我最好的。
