海洋植物 marine plants
海洋中利用叶绿素进行光合作用以生产有机物的自养型生物。从低等的无真细胞核藻类到高等的种子植物，门类甚广，共13个门，1万多种。其中硅藻门最多，达6000种；原绿藻门最少，只有1种。海洋植物以藻类为主。海洋藻类是简单的光合营养的有机体，其形态构造、生活样式和演化过程均较复杂，介于光合细菌和维管束植物之间，在生物的起源和进化上占很重要的地位。海洋种子植物的种类不多，只知有130种，都属于被子植物。可分为红树植物和海草两类。它们和栖居其中的其他生物，组成了海洋沿岸的生物群落。
海藻是海洋植物的主体，是人类的一大自然财富，目前可用作食品的海洋藻类有100多种。科学家们根据海藻的生活习性，把海藻分为浮游藻和底栖藻两大类型。
蓝藻、硅藻、甲藻、金藻和部分单细胞的绿藻，很多是海洋动物如甲壳类、贝类、海参、梭鱼、锱鱼和鲸类的饵料，对海洋动物的增养殖具有重要的作用。中国沿海常见的蓝藻约200多种，藻体具有胶质，蓝绿色或墨绿色，比较粘滑。红藻约500余种，多数呈红色，暗红色或紫红色，经济价值比较大，资源比较丰富，中国沿海比较常见的约250余种。有些种类已经进行人工养殖，如：红毛菜、紫菜、麒麟菜等，都是人们喜爱的食品；石花菜、琼枝、江篱、角叉菜、凝花菜等是琼胶和卡拉胶等医学和食品工业的原料；表面具有碳酸钙包被、外型像珊瑚似的石枝藻、鹧鸪菜和海人草等都是医药工业的主要原料。褐藻约300余种，中国沿海比较常见、经济价值比较大、资源比较丰富的约有150余种。目前已进行人工养殖的海带、裙带菜、羊栖菜，都是褐藻胶、甘露醇、碘和氯化钙的主要工业原料，又是人民喜爱的食品，这类褐藻主要生长在黄渤海和东海沿岸。马尾藻自然资源丰富、种类最多、经济价值很大的一类褐藻，主要产于中国南海。
爱尔兰人民历史上也有过依赖红藻、绿藻度过饥荒年的记载。西方国家食用海藻的习惯不如东方国家普遍。一位西方国家的海洋学家曾发出感叹：中国、日本人食用海藻就像美国人、英国人吃番茄一样普遍。他希望有一天，西方人也像东方人那样养成食用海藻的习惯。
海洋种子植物种类较少，主要生长在低潮带石沼中或潮下带岩石上，常见的有大叶藻，红须根虾形藻和盐沼菜，都是重要的经济种类，主要用于造纸和建材工业。
海洋动物
marine animals
海洋中异养型生物的总称 。门类繁多，各门类的形态结构和生理特点可以有很大差异。以摄食植物、微生物和其他动物及其碎屑有机龟质为生。估计有16～20万种，微小的有单细胞原生动物，大的有长可超过30米、重可超过190 吨的蓝鲸。全球海洋的水体及其上空，从海上至海底，从岸边或潮间带至最深的海沟底，都有海洋动物。
海洋动物可分为海洋无脊椎动物、海洋原索动物和海洋脊椎动物等3类：①海洋无脊椎动物。占海洋动物的绝大多数，门类最为繁多。主要的有原生动物、海绵动物、腔肠动物、扁形动物、纽形动物、线形动物、环节动物、软体动物、节肢动物、腕足动物、毛颚动物、须腕动物、棘皮动物和半索动物等。②海洋原索动物。海洋中介乎脊椎动物与无脊椎动物之间的动物。包括尾索动物和头索动物等。③海洋脊椎动物。包括依赖海洋而生的鱼类、爬行类、鸟类和哺乳类动物。
分布在海洋中的动物群。海洋的生活条件相对一致，面积广大，动物中除鱼类、鲸类，还有浮游动物和游泳动物，如头足类和水母等。在深海层，仅发现不依赖浮游生物生存的动物。
在许多大洋区，海流将营养丰富的深层海水带到浅层，使海洋浅层带增加了鱼类产量。在海底生活的底栖动物，包括固着动物，如海绵、腔肠动物、管沙蚕等和运动动物，如甲壳类、贻贝、各种环节动物、棘皮动物等。
珊瑚动物在热带海洋发展最充分。珊瑚礁是由大量建礁动物和植物的白垩质骨骼物质（特别是珊瑚和苔藓虫）沉积而成的。在珊瑚礁环境中动物最密集且最多样化。
鲨鱼英文短句
Dolphin
In the vast ocean live many creatures with great intellectual and physical capacities. Dolphin is one of those great creatures, whose capacities to think and move at an astounding rate puzzle those who study their behaviors, Dolphins possess something that makes them different from all the other sea creatures. It is not strength or speed but the size of their brains. Dolphin' s brain is almost the same size as that found in the human head. They live for a ling time.
Dolphins' babies are born in the water. They can grow up to three and a half meters long.
Dolopins use sound to help them find their way, look for their food and talk with each other. Sound is just like their eyes and mouths.
海豚
大海里住着许多智力发达、身体强健的动物，海豚就是其中之一。它反应灵敏、动作迅速，让那些研究它们行为的人们深感震惊。海豚拥有一些与其它海洋生物不同的地方，它的优势不在于它的力量和速度，而在于它的大脑。海豚的大脑与人脑大小一样大。它们的寿命很长。
海豚在水里生育，它们能长到三点五米长。
海豚利用声音帮助自己认路、觅食与彼此之间交谈。声音就像它们的眼睛和嘴一样。
1.用英语介绍一种鲨鱼用6句话
鲨鱼，被一些人认为是海洋中最凶猛的鱼类之一。但鲨鱼中体型最大的鲸鲨却以小型海洋生物为食物，和须鲸差不多。由于食物具有某种相似性，经过漫长的生物演化，它们长得和须鲸很有相似点，这个叫做“趋同进化”。于是“鲸鲨”的名字就理所当然了。
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.

3.形容动物特点英语句子（猴子 大象 蓝鲸 鲨鱼 鳄鱼）我知道Elephant animal totem If the United States is Turtle Island, a continent supported on the back of a turtle, then India would be Elephant Island, a continent supported on the back of an elephant. Throughout the centuries, Indian tradition dictated that all royalty the rulers of the land, be home on the backs of the children of the great beast that carried the world through space. The elephant was the totem animal of the god Shiva, the Destroyer, who seeks to banish illusion and to encourage a clearer perception of reality Shiva and his goddess-spouse, Radha, produced among their children the elephant-headed god Ganesha, who, as Lord of Ilosts, impregnated the virgin Maya to bring Buddha into flesh. Especially sacred in India was the white elephant, considered far too priceless to be used for work or warfare, but to be maintained by its owner in the finest of style. When we speak today of a "white elephant" purchase, we have realized too late that we have purchased an object at a price that exceeds its true value. Sometimes seen as a symbol of great sexual prowess in the Asian countries, the Chinese portray the elephant as representative of royalty, strength of purpose, and discretion. In the widest, most universal, and most obvious depiction of the elephant it is a symbol of strength. At various times in Medieval Europe, the elephant also became an emblem of wisdom, moderation, and eternity Then, accomplishing a complete change of cosmology, there appeared the elephant-headed demon, Behemoth, a favorite in Dark Side sorcery. If you have accepted the elephant as your totem animal, it may not be long before you are asked to assume a role of great responsibility in the workplace or in your community. If you feel attracted to the elephant as a totem animal, it is likely that you are involved in social work, public service, or politics. You may also feel a strong commitment to caring for the ill, the very young, and the elderly. Whenever you sense an injustice, you will be there on the side of the underdog. As your spirit helper, the elephant will be able to draw you back to a greater appreciation for the ancient mysteries than you have previously experienced. You will soon discover that your guide is extremely concerned about your maintaining always a solid balance of body, mind, and spirit. Under the tutelage of this spirit helper, you will place your time in the Silence as your top priority. You might find yourself wishing to burn some incense while you are meditating with this totem animal in order to help create an environment in which exploration of other higher levels of consciousness will be the rule, rather than the exception.。
