英文： You must be curious about how such a large North Pacific right whale became a specimen. First, removed the dirt on the whale’s body, measured the weight, peeled the skin, soaked it in the preservative liquid, dehydrated to remove the grease, and then applied the preservative and insect prevention substance on the inner skin. After finishing the process of dealing with the skin, forged the keel with iron tubes, steel angles and wood, accurately measured the size of the skin, tossed the whale skin on the keel and then sutured them together. After the production, air dried the specimen, and finally mixed the colors and painted according to the whale’s color. Such a large specimen of the whale then have come up in front of us.

The baby whale next to her is her fetus, which was dissected from her abdomen during the specimen preparation. The whale is a kind of mammal, although it lives in the ocean, it is still viviparous like other mammals and the baby whale also feeds on breast milk. I believe that it’s hard for you to imagine how a whale suckles in water. They don’t feed by actively sucking, they feed by the mother whales to spray the milk into the water, isn’t it special. Instead of having protruding curves on their breasts like those of other mammals such as humans, female whales have a pair of nipples hidden in a skin groove. Only during lactation, the long and thin nipple will reach out from the groove, at this moment, the baby whale will twine its tongue around the nipple and keep it in its mouth. After this, the female whale will eject milk into the baby whale’s mouth. Each injection is about ten kilograms of milk, which takes about 10 seconds to complete a lactation.

中文：您一定很好奇，眼前這么大的北太平洋露脊鯨是如何做成標(biāo)本的呢？首先工作人員要清除鯨體上的污物，測量體重，剝皮，浸泡防腐，脫水去油脂，然后在內(nèi)皮層涂防腐防蟲的物質(zhì)。皮張?zhí)幚硗瓿珊?，要用鐵管、角鋼、木方打造龍骨架，精確測量皮張的尺寸，將鯨皮披到龍骨架上，進(jìn)行縫合。制作完成后透風(fēng)風(fēng)干，最后根據(jù)鯨的顏色進(jìn)行調(diào)色刷色。這樣大型的鯨類標(biāo)本就和我們見面了。

旁邊的小鯨是她的胎兒，是工作人員在制作標(biāo)本的時候從她的腹中解剖出來的。鯨是哺乳動物，雖然生活在海里，但它仍然和其他的哺乳動物一樣，是胎生的，鯨寶寶也要吃奶。但相信大家很難想象鯨是如何在水中哺乳的呢？它們并非靠主動吮吸來吃奶，而是依靠母鯨噴射奶水的方式進(jìn)食。母鯨的乳房并不像人類等哺乳動物一樣有突出的曲線，相反，它們有一對隱藏于皮膚溝中的乳首。只有在哺乳時，細(xì)長的乳首才會從溝中伸出，這時候，鯨寶寶就用舌頭把乳頭卷住，再用口銜住乳首。之后母鯨就會將鯨奶噴射到它的嘴里。每次噴射十公斤乳汁，大概十秒左右就完成一次哺乳。
