1.恐龙蛋√
恐龙是如何繁殖的,胎生还是卵生?恐龙蛋是恐龙繁殖的直接证据,它能告诉我们许多有关恐龙繁殖的信息。我国是盛产恐龙蛋的大国,仅河南西峡发现的恐龙蛋就有几十万枚,而世界其它地区所有地方发现的恐龙蛋才几万枚。这里展出的有来自河南西峡的一窝恐龙蛋,它是由张硕麟先生捐赠给本馆的。恐龙产卵一般选择在向阳的山坡上,一窝可产几枚或几十枚。不同种类的恐龙产卵数量、形状和排列方式各有不同,目前发现的恐龙蛋形状主要有长形、圆形.椭圆形等。除了个别恐龙蛋外,大部分的恐龙蛋现在还不能知道是哪种恐龙所产,因为发现恐龙蛋的地点,很少能找到恐龙骨骼化石,发现恐龙化石的周围也很少能找到恐龙蛋。工作改进
恐龙蛋的直径大小一般都在十几厘米左右,小的如鸡蛋大小,最大的也就篮球大小,那为什么能长成十几米高的庞然大物呢?这是因为恐龙是终生生长的,而且恐龙的寿命比较长,平均寿命为120岁,最长寿的恐龙能活到200岁。
1Dinosaur egg
Dinosaur egg is the direct evidence for dinosaur breeding, which tells us much information about dinosaur’s breeding, disappearance, ancient environment and so on. Our country is the big country that produces dinosaur eggs, only in Henan Zhechuan Basin ten thousands of dinosaur eggs are disco
vered. The one showed here is a brood of dinosaur eggs discovered in Xixia, Henan donated to our muum by Mr. Zhang Shuolin. Generally dinosaur choos to lays eggs on the hillside with a sunny exposure, one time it could lay veral eggs, over hundred eggs and so on. The dinosaur eggs are not hatched directly by dinosaur, but hatched by irradiation of sun. A different dinosaur leys different amount, different shape and different arrangement egg. Up to now the shapes of dinosaur eggs we discovered are mainly long, round, ellip and so on. Except individual dinosaur eggs, as for most of the dinosaur eggs, we could not know which kind of dinosaurs laid them. But with electronic instruments rearch the eggshell of dinosaur eggs, scientists could conduct the detailed classification for the dinosaur eggs, and they could obtain the information such as the reasons of dinosaur disappearance and so on from the dinosaur eggs.

Some people think it is the weapon attacking each other; some people think the cresting is ud to store air in water; some people think the cresting is the no structure; also some people think the cresting is smell organ.

3.矮胖的北太平洋露脊鲸√
北太平洋露脊鲸长得可没有长须鲸标志,它们的身体短粗,没有背鳍。头部巨大,而且上面长有古怪
购物中心管理而又坚硬的斑点。刚出生的小鲸可没有这种古怪的斑点,只有长大后才出现,科学家们称这种皮肤是愈创组织,可以用来识别不同的个体。大多数的北太平洋露脊鲸生活在北大西洋的西部。磷虾、杯足动物和甲壳类动物是它们的主要食物。由于它们游动的速度很慢,比较容易接近,成为捕猎的主要目标。捕鲸人称它们为“Right whale”,中文意思是“好鲸”。巴斯克人早在11世纪就在西班牙的比斯开湾对它们进行捕杀。近些年由于人类的过度捕杀,它们已经处于行将灭绝的境地。目前只剩下300多头幸存的北太平洋露脊鲸,如果我们再不好好保护,我们的后代就只能在博物馆瞻仰它们的遗体标本了。
展厅的北太平洋露脊鲸的外形和骨骼标本,是1977年辽宁海洋渔业公司在黄海北部海域捕获的,雌性,全长17.10米,体重约66.7吨,是我国保存的鲸类动物标本中体重最大的。旁边的黑露脊鲸胎儿是她的后代。
3. Stout northern right whale
The northern right whale is short and wide, no dorsal fin. The huge head is covered with strange and hard spotted skin. When born the baby whale has no such strange and spotted skin, only when they grow up could the spotted skin appear.

Atlantic, but sometimes they also could be en in east part of North Atlantic and east part of North Pacific. They mainly eat krill, copepoda and other crustacean. The female whale only when they grow up to 5 to 10 years could they give birth to their baby, and they could only give one birth each 3 or 4 years. The whaleman mostly like to catch the northern right whale, in early 11 century the Basker whaleman began to catch and kill a great deal of northern right whales in Basky Gulf of Spain. Becau they swim very slowly, so easy to reach them, and become the best object to catch, they are called “right whale” by the whaleman, means “good whale”. After excessively catching by humankind for many years, this kind of whale is just clo to extinct. Though in 1937 they are defended by human, but only 300 black right whales survived luckily could never recover their past prosperousness.

4.海兔三绝√
海兔的头颈上有触角和嗅觉器官各一对,形似兔耳,故名海兔。狡兔有三窟,海兔有三绝。
第一绝是生殖方式。每只海兔都是雌雄同体,到春、秋两季,大量的海兔串联在一起,象一条长绳,除首尾两只外,其余每只都既是父亲又是母亲,即同一只海兔对前面的来说是父亲,对后面来说又是母亲。
第二绝是拟色。出没于海底藻林中的海兔,为保护自己,练就了一门奇妙的“隐身术”,
它吃墨角藻时,体色会变成墨绿色;吃红藻时,变成玫瑰色;吃海带时,又会变成褐色。
第三绝是擅长“化学战”。海兔体内有两种特殊腺体,一种是毒腺,危急时能释放带酸味的乳状液体,将对手的神经麻醉。另一种是紫色腺,遇见敌人时,打开“扳机”放出紫红色烟幕,使对方误以为自己被击中出血,而海兔则趁机逃之夭夭了。

7.怎样区别魁蚶、毛蚶和泥蚶√
魁蚶、毛蚶和泥蚶都属于双壳类软体动物,他们的外形也很相像。区别三者的主要依据首先是其放射肋的数量。魁蚶壳表有42条左右规则的放射肋,肋较宽,无明显结节。毛蚶表壳通常有31—34条规则的放射肋,左壳及右壳前端肋上有明显的小结节,同心生长线在腹部较明显。泥蚶有17—20 条发达粗壮的放射肋,肋上有大而稀疏的结节,肋间隙较放射肋稍宽。
另外,就成体而言,魁蚶比其它二者要大得多。

All blood shell, ark shell and bloody clam belong to bivalve mollusk, they also have similar shape. The evidence for the difference of the three ones is that the amount of their radiation rib. The shell of
blood shell has about 42 regular radiation ribs, and the ribs are wider, no evident nodes. The shell of ark shell usually has 31-34 regular radiation ribs, the left shell and right shell has evident small nodes on their front ribs, the concentric growth line on abdomen is more evident. The shell of bloody clam has 17-20 developed thick and strong radiation ribs, it has large and spar nodes on the ribs, the clearance of ribs is a lit bit wider than the radiation ribs.
Besides, for the adults the blood shell is much larger than the other two shells.

孔,足丝由这里出入,在砗磲发育期间,胶质的足丝牢固地沾在岩礁上,因而不能自由游动。它的外套膜绚丽多彩,有粉红、翠绿、孔雀兰等颜色。砗磲靠虑食海水中的微小浮游生物为生,库氏砗磲是砗磲中最大的一种,它的闭壳肌特别发达,象“弹簧”一样有力,因此采捕工作很特别。由于它个体大,固定在礁石上,不易搬动,所以多是潜水员趁砗磲把两贝壳展开时,将錾子插进壳内,割下贝肉。砗磲肉可食,尤其是闭壳肌很肥大,味道鲜美。砗磲是贝中的老寿星,据说可以活数百年。

10.东北森林展厅简介√
郁郁葱葱的森林是地球上最具生物多样性的生态系统,是人类最重要的环境资本。森林不仅为人类提供氧气、木材、药材,而且在涵养水源、调节气候、保持水土和防止土壤沙化,降解环境污染等方面起着极其重要的作用。
我国是一个森林资源贫乏的国家,森林覆盖率仅为百分之十三,低于世界百分之二十二的平均水平,在160个国家和地区当中只列120位。东北森林是我国重要的天然森林。其中
