金蟬脫殼為哪樁？甲殼類其體表披著幾丁質之外骨骼，其外殼堅硬如同盔甲一般。蝦、蟹類等十足目，是人們所熟悉的甲殼類動物，蝦、蟹平時不成長，但藉由脫殼後幾天新殼尚未硬化前，吸收大量水分迅速增大身體。因此蝦、蟹類『金蟬脫殼』主要是為了成長，蝦類脫殼由頭胸部開始，其後是尾部；蟹類則從腹甲後緣開始，然後附肢。
Why does Crustaceans molt? Crustaceans have gelatin exoskeleton, which is as hard as a warrior's armor. Shrimps and crabs belong to Order Decapoda and they are quite familiar to people. Shrimps and crabs cannot grow unless they molt. Their body absorbs water and swells after molting. So, the purpose of molting is for them to grow. There are some differences in the molting of shrimps and crabs. Shrimps molt from the cephalothorax ending in the tail. Crabs molt from the abdomen and end in the appendages.

看了肥美的龍蝦，接下來看看其他「甲殼類展示區」，這幾種美麗的蝦子感覺都是不能吃了，是放在水族缸中看水的類型。

縱紋邊藻蝦(清潔蝦)(Lysmata amboinensis)

櫻花蝦(美人蝦)(Stenopus hispidus)

綿羊蝦(Saron marmoratus)

這隻倒掛在岩石上的美人蝦，就這樣跟我兩個大眼瞪小眼，長長的觸鬚，身上紅白相間的花紋，真的是很賞心悅目。

可能聽到我的讚美，這隻美人蝦特地離開洞穴，到前面來展示一下他美麗的身影，順便和底下的海葵打打招呼，真是一兼二顧哪！

貝類之成長：貝類屬軟體動物，是地球上第二大群的動物。貝殼是來自其外套膜的分泌物，所以貝殼是會長大的。通常被類都有他生長的極限，到一定大小及停止長大，但外套膜卻繼續分泌，這時生長的作用只是在增加貝殼的厚度。貝殼上常可見疤痕，每一疤痕都代表生命中的一些遭遇，根據其疤痕約略可以看出依玫貝殼生命中的一些陳年往事。
Growth of shellfish: Shellfishes belong to the family of mollusks and are the second largest population in the animal kingdom. The shell comes from a secretion from the mantle and will continue to grow until the size limit is reached. Mantle secretion continues to increase shell size. There are always some scars on the shell representing disastrous events in the shell fish's life. People can read the shell scars to know what happened in their life history.

有點嚇到我的「貝殼類展示區」，在我的印象中，貝殼大多只有我的手掌大，沒想到這裡都是像在DISCOVERY節目中看到的鍋子般大小，沒誇張，若是有機會，一定要到海生館實地看看。

夜光蠑螺(Turbo marmoratus)

銀塔鐘螺(Tectus pyramis)

黑星寶螺(Cypraea tigris)

這一大堆的貝殼都很大，比鍋子還大，但是很奇怪的我比對上面的圖片，就是對不起來，難不成貝殼長大了還會變形？

和岩石顏色很接近的貝殼，都要仔細的看才知道，不然這麼棒的保護色，常常讓我的眼睛一時之間看不真切哪！

每個貝殼都有自己的一段故事，而且上面的每個刻痕也都其來有自，不過在這裡養尊處優的巨無霸貝殼們，應該沒那麼滄桑吧？

魚毒與毒魚：全世界的有毒魚類約在300種以上，均分佈於南、北回歸線內之海域。據研究台灣海域至少有80種以上之毒魚，除「食毒」魚類外，亦包括25「刺毒」魚類。「食毒」魚類魚體的肌肉、內臟、皮膚、生殖腺或黏膜含有毒性物質，通常不會被熱或胃酸破壞，如河魨毒；而「刺毒」魚類則係於體有毒腺分泌毒液，並且有製造外傷用來釋出毒液之硬棘，如獅子魚。
Poisonous and toxic fishes: There are over 300 species of toxic fishes in the world which arre distributed mainly in the subtropical areas. In Taiwan, there are over 80 species of toxic fishes that include inedible ones and 25 species with toxic spines. The toxic material may be located in the muscle, organ, skin, reproductive organ, or mucus gland. The poison, such as that in the toxic puffer, cannot be destroyed by heat or acid. The fish with toxic spine, such as the lionfish, has a poison gland that secretes toxic solution through the spine when attached by predators.

應該可稱為蛇蠍美人的「有毒魚類展示區」，這些種類的魚不管是圓的扁的，有帶刺的沒帶刺的，都是有毒的，雖然有毒，卻很美麗，尤其是那有著漂亮彩帶的獅子魚，就像是個體態輕盈的仙子，優游在海洋中。
