Community composition simply refers to determining the constituent species of a particular location. For instance, Kending's Banana Bay is predominantly stony coral, while in the area near Maobitou Alcyonaria or soft corals reign supreme, and within Nanwan Bay the composition varies significantly from place to place.
「所謂『群聚組成』，就是弄清楚每個區域是由哪些主要種類組成，」例如墾丁的香蕉灣是以石珊瑚為主的群聚、貓鼻頭附近則是以軟珊瑚為主，而南灣海域的不同地點差異則很大。
