在一般情况下,任何动物只要碰到海葵,就会被海葵的花瓣状触手麻醉或杀死。但是,双锯鱼却能自由自在地穿梭于海葵的触手间,这是怎么回事呢?(小好奇)海葵是无脊椎动物,没有骨骼,因外形像葵花而得名。大多数海葵栖息在海底的岩石和珊瑚上,有的海葵栖身于海底的泥沙中,有的海葵能用触手在水中游泳。海葵是捕食性动物,它的触手上布满了捕食和防御的武器——刺细胞。因为海葵的触手有毒,所以一般的鱼都不敢接近它。但是,有一种小鱼却不怕海葵的触手,它与海葵生活在一起,是海洋动物共栖的一个典型例子。
Under normal circumstances, whenever an animal encounters an anemone, it will be anesthetized or killed by the petals of anemone. However, the amphibious fish are free to shuttle between the anemones tentacles, what is going on? (Curiosity) Anemone is an invertebrate, no bones, because of the shape of the sunflower named. Most sea anemone habitat in the rocks and coral on the sea floor, and some sea anemone habitat in the sediment of the sea, and some anemone tentacles in the water swimming. A sea anemone is a predator, and its tentacles are covered with predators and defensive weapons - spiny cells. Because anemones tentacles toxic, so the fish are generally not close to it. However, there is a fish that is not afraid of the anemone’s tentacles. Living with sea anemone, it is a typical example of the coral habitat of the sea animals.
