楯手目的一科棘皮动物 来自维基百科,自由的百科全书
海參科(學名: Holothuriidae)是一個海參綱棘皮動物的科,舊屬楯手目[2],今屬海參目[1]。
海參科的成員有厚厚的肉質身體和幾排管足,用於四處移動和黏附在表面上。身體通常覆蓋着稱為乳突的鈍突起。本科許多成員都能夠噴射出大量被稱為居維氏管的細線來分散捕食者的注意力,甚至將它們的內臟翻過[3] 來。 For the taxonomic determination, the genera Actinopyga and Bohadschia have their spicules exclusively shaped like sticks, and the genera Holothuria and Labidodemas never have theirs shaped like tables. Actinopyga is also equipped with anal teeth (modified podia), and never throw out Cuvieran tubules, just like Pearsonothuria.
Members of this family occur throughout the oceans of the world at low to middle latitudes. They often live in 珊瑚礁s and nearby sandy habitat types, and a few occur in deeper waters. In the 印度洋-太平洋海域 they are often dominant taxa in coral reef habitat. Most species are 食碎屑動物s.[4]
