如下:
A couple of days ago, my dad and I go to the supermarket to buy things. Kingwe saw the sea shark, a shark that is cut in two, I think: sharks in the ocean so ferocious, and King of the sea anyway! But for now, or are we human beings killed, for sale, sell us to eat.
In my opinion, there seem to be two kinds of sharks (character), but the fact that sharks have only one character, in my imagination, the first is: fierce sharks, second: no use of sharks.
In these two species of shark, ferocious sharks is under what circumstances could use the title of it? Is swimming around in the ocean, and very handsome King in front of the sea. Useless shark is a shark be captured by humans, killing, for sale with title.
In the evening, father settle when I went to bed, my dad said to me: today we see that the shark was cut in two in the future will be eaten by humans, do we humans are cruel, dont you think?
I replied: its very cruel, but, if not cruel, we would starve. Because we still have to eat meat or something. Also, what other herbivores, for example eating cattle, sheep, and our homes not turned into a desert.
Grass, we have better homes. But we are a little cruel. Dad just smiled and walked out of my room.
鯊魚的資料(英文)
鯊魚屬于脊椎動物門軟骨綱(Chondrichthyes)板鰓亞綱,海生,少數(shù)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(nèi)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(fā)達或退化,身體常被皮齒(質(zhì)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.
上額由腭方軟骨組成,下額由梅氏軟骨組成。最新研究表明,鯊體內(nèi)含有多種生物活性成分,如抗癌因子、角鯊烯、黏多糖等等。
On the forehead is composed of palatal side cartilage, the forehead is composed of Mr Medvedev cartilage.Sharks, according to new research in the body contains a variety of biological active ingredients, such as anti-cancer agent, squalene, mucopolysaccharides and so on.
擴展資料
鯊魚的起源不詳,但其地質(zhì)學(xué)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(xiàn),在石炭紀(3.6億~2.86億年前)成為占優(yōu)勢的脊椎動物?,F(xiàn)代鯊魚出現(xiàn)于侏羅紀早期(2.08億~1.87億年前),到白堊紀(1.44億~6,640萬年前)已經(jīng)發(fā)展成現(xiàn)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(tài)改變甚微。無論對化石種和現(xiàn)存種類來說,牙齒在鯊魚種類鑒別方面均有很重要作用。

The biggest whale shark can grow to twenty meters in length. Sharks do not have bones. The skeleton of a shark is made of cartilage. Human noses and ears are also made of cartilage.
A shark has an extremely good sense of smell. It can find small amounts of substances in water, such as blood, body liquids and chemicals produced by animals. Sharks also sense electrical and magnetic energy linked to nerves and muscles of living animals.
