天生絕配(Perfect Match)

雖然海葵有會分泌毒液的有刺觸手，但因小丑魚身體表面會分泌特別的黏液，使海葵觸手的刺絲胞不會被觸發，遂成為保護小丑魚不受天敵攻擊的守護神。居住在海葵間的小丑魚，除了會趕走海葵的掠食者，也可能會誘引掠食性魚類前來攻擊，而成為宿主海葵的食物，回家讓海葵免費享用。小丑魚也會移除海葵身上的寄生蟲、壞死組織與清潔宿主身上的碎屑。海葵與小丑魚的互利共生模式，無疑是海裡的天生絕配。

Stinging tentacles of sea anemones are armed with nematocysts that contain toxins. Mucus secreted by clownfish covers its entire body and keeps the nematocysts calm so that the fish are well protected from predators among host tentacles. In return, the fish symbionts drive away natural enemies of anemones and lure prey for their hosts. Clownfish also remove parasites, dead tissue and debris from anemones. Such mutualistic symbiosis makes anemones and clownfish the perfect underwater match.
