③ 鯊魚的簡介
鯊魚屬於脊椎動物門軟骨綱(Chondrichthyes)板鰓亞綱，海生，少數種類進入淡水，為一群游速快的中大型海洋魚類。
外形特徵：
體呈長紡錘形。鰓裂側位，胸鰭正常，不與吻的前緣癒合；北鰭背位；歪尾型。
身體呈紡錘狀，頭兩側有腮裂，但類似普通魚。除個別例外，典型的鯊魚皮膚堅硬，呈暗灰色，牙齒狀鱗片使皮膚顯得粗糙。尾部強壯有力，不對稱、上翹；鰭呈尖狀；吻尖，前突，吻下有新月形嘴及三角形尖牙。鯊魚無鰾，需不停地游泳以免沉到水底。
物種概述
1、大白鯊是最大的食肉魚類，為軟骨魚綱鼠鯊目鼠鯊科的其中一種，大白鯊是卵胎生的魚類，身長可達6米多，體重超過3噸，牙長10厘米。分布於各熱帶、亞熱帶和溫帶海區、在澳洲海域最為常見以及南海、東海、黃海及渤海等海域，屬於大洋性活潑健游種類。大型進攻性鯊魚，危險！虎鯨是大白鯊唯一的天敵。
2、巨口鯊，是鼠鯊目的一科，只有一種巨口鯊，是新發現的一個品種，目前全世界發現數量不到50隻，相當罕見。第一隻巨口鯊是在1976年於夏威夷外海發現的。巨口鯊分布在印度洋，太平洋、大西洋，棲息深度約5至1000米之間，以深海居多，故很少被捕獲。
3、淺海長尾鯊，又名淺海狐鮫或遠海長尾鯊，是軟骨魚綱鼠鯊目狐鮫科的一種。分布於印度太平洋區，為大洋性大型鯊魚，肉食性，主要以魚、飛魚及遠洋魷魚為食物。卵胎生。
4、沙虎鯊，又名戟齒砂鮫或戟齒錐齒鯊，是一種生活在海岸海域的大型鯊魚。現正分布在大西洋、印度洋及太平洋不同的地方。沙虎鯊的外表兇猛，但它們往往很溫順，除非受到挑釁，否則它並不帶有攻擊性。食物主要有硬骨魚（包括大海鱸）、其他鯊魚及魚、魷魚、蟹及龍蝦。

⑤ 用英語介紹一種鯊魚用6句話
鯊來魚，被一些人認為是海自洋中最兇猛的魚類之一。但鯊魚中體型最大的鯨鯊卻以小型海洋生物為食物，和須鯨差不多。由於食物具有某種相似性，經過漫長的生物演化，它們長得和須鯨很有相似點，這個叫做「趨同進化」。於是「鯨鯊」的名字就理所當然了。
The shark, considered by some to be one of the most ferocious fishes in the sea. But the shark in the largest whale sharks with small sea creatures for food, and whales almost. Because the food has some similarities, over a long period of biological evolution, they grow and whales very similar. This is called "convergent evolution." So the "shark" the name of behoove.
⑥ 鯊魚的資料（英文）
鯊魚屬於脊椎動物門軟骨綱(Chondrichthyes)板鰓亞綱，海生，少數種類進入淡水，為一群游速快的中大型海洋魚類。
Sharks are vertebrates steel door cartilage (Chondrichthyes) elasmobranchii, Marine, a few species enter fresh water, as a group of large Marine fish speed is fast.
鯊內骨骼完全由軟骨組成，常鈣化，但無任何真骨頭組織，外骨骼不很發達或退化，身體常被皮齒(質鱗)，牙多樣化，具有硬肌，但膜骨則永不存在，腦顱無縫。
Shark endoskeleton completely composed of cartilage, often calcified, but without any true bone tissue, degraded or exoskeletons is not very rich, the body is often skin teeth (scale), tooth diversification, with hard muscle, but never exist, membrane bone temple seamless.
上額由齶方軟骨組成，下額由梅氏軟骨組成。最新研究表明，鯊體內含有多種生物活性成分，如抗癌因子、角鯊烯、黏多糖等等。

(6)鯊魚用英語怎麼介紹擴展閱讀
鯊魚的起源不詳，但其地質學紀錄可追溯到泥盆紀(4.08億～3.6億年前）。鯊魚化石在中泥盆世出現，在石炭紀（3.6億～2.86億年前）成為占優勢的脊椎動物。現代鯊魚出現於侏羅紀早期（2.08億～1.87億年前），到白堊紀（1.44億～6,640萬年前）已經發展成現存的各科。
總之，除覓食和游泳機制的改進外，進化對鯊魚的形態改變甚微。無論對化石種和現存種類來說，牙齒在鯊魚種類鑒別方面均有很重要作用。
