本文描述了35种大西洋礁珊瑚的纤毛流,并与太平洋珊瑚的纤毛流作了比较。在白天和晚上,在进食和不进食期间进行观察。有一个基本模式的纤毛电流共同大西洋和太平洋物种。除了伞菌科以外,所有伞菌的电流都从口盘流出,并在触手之间向上或向外流动。在圆盘区域的中心,电流流向口或口唇。在珊瑚柄或柱上,大西洋和太平洋两种类型的物种之间存在相当大的差异。在某些物种中,电流向下流向共囊体,而在另一些物种中,电流向上通过茎流向触手。 在大西洋伞菌科中,可能有一个向内的流向嘴,一个向外的流动或一个单向的流动穿过珊瑚。流动的模式取决于息肉的收缩状态或相邻息肉的形状和接近程度。 在大西洋物种中没有观察到纤毛电流逆转。纤毛电流作为一种清洁机制发挥作用,并促进粘液网和粘液链聚集颗粒的能力。
Patterns of ciliary currents of 35 species of Atlantic reef corals are described and compared with currents of Pacific corals. Observations were made during the day and at night, during feeding and without food. There is a basic pattern of ciliary currents common to both Atlantic and Pacific species. In all but the family Agaricidae currents flow off the oral disk and up or out between the tentacles. In the centre of the disk region currents flow towards the mouth or the peristome. On the polyp stalk or column there was considerable variation between species in both Atlantic and Pacific forms. In some species currents flow downwards toward the coenosarc while in others, current pass up the stalk towards the tentacles. In the Atlantic Agaricidae there may be an inward flow towards the mouth, an outward flow or a unidirectional flow across the corallum. The patterns of flow depend upon the state of contraction of the polyps or the shape and proximity of adjacent polyps. No ciliary current reversal was observed in Atlantic species. Ciliary currents are functional as a cleansing mechanism and facilitated the ability of mucus nets and strands to gather particles.
