世界上的海洋占地球表面积71％,在3.62亿平方千米的水域中,生活着18万种千姿百态的各类动物。其中,在较原始的腔肠动物门中有一类海葵,因其在柱状体端部有若干的中空触手,状似菊瓣,故而又称作“海菊花”。海葵生命力极强,在海洋中可活百年以上,室内饲养也可活70余年,真是海洋中百岁长寿菊。据称,全球有海葵5千余种,已研究过的只是少数。我国动物志已记载的海葵有109种,分隶于16科42属。
The world’s oceans account for 71% of the Earth’s surface area. In 362 million square kilometers of water, there are 180,000 species of animals of all shapes and sizes. Among them, there is a kind of anemone in the primitive coelenterate door, because it has a number of hollow tentacles at the end of the columnar body, resembling a daisy, so it is also called “sea chrysanthemum.” Anemone has a strong vitality, can live in the ocean for more than a century, indoor breeding can live for more than 70 years, is really a hundred years old marine chrysanthemum. It is said that there are more than 5,000 species of sea anemones in the world and only a few have been studied. There are 109 species of sea anemone recorded in China’s animal records, which belong to 42 families and 42 genera.
