海星属棘皮动物,是海洋里常见的大型无脊椎动物,种类很多,有些种类喜食牡蛎、贻贝和蛤蜊等软体动物,是贝类的重要敌害,故被认为是一种有害生物。 我国黄、渤海捕捞底层鱼类时,往往同时捕到相当数量的海星,最多网头可达200箱,但都随时弃之于海,或者带回来做肥料,甚为可惜。 Starfish is an echinoderm, which is a large invertebrate common in the oceans. There are many species of mollusks that are popular with the shellfish, such as oysters, mussels and clams. They are considered as pests. When China and the Yellow Sea and the Bohai Sea catch fish on the ground, they often catch a considerable number of starfish at the same time, with a maximum of 200 nets. However, it is a pity that they will be discarded to the sea at any time or brought back as fertilizer.
