在库拉考和博内尔岛（荷属安的列斯群岛）珊瑚礁3-37米深处对幼珊瑚的分布和丰度进行了检查。幼蜂以蘑菇蘑菇最多（60.6%），其次是尖叶银缕草（8.3%）。大型块状珊瑚，如Montastrea annularis、M.海绵珊瑚和分枝珊瑚如Madracis mirabilis和Acropora palmata几乎没有幼体。这与物种特征相结合，表明这些物种采用非常不同的生活史策略。在一些物种中，珊瑚礁上的幼鱼数量超过了较大群体的数量，但不是例如Agaricia agaricites。的珊瑚群落的组成显然是没有直接功能的少年丰富。A沉降角度的变化。随着深度的增加，从垂直到水平表面，agaribities青少年似乎反映了首选的光强度。在1/2年的时间内，研究了幼珊瑚的存活情况。三分之一没有受到伤害，三分之一死亡或消失，三分之一因空间竞争等因素而生长受限。这是相同的所有深度，但影响生存的因素随深度而变化。
The distribution and abundance of juvenile corals were examined at depths from 3-37 m on the reefs of Curacao and Bonaire (Netherlands Antilles). Juveniles of Agaricia agaricites were most abundant (60.6%), followed by Helioseris cucullata (8.3%). The large massive corals such as Montastrea annularis, M. cavernosa and branched species such as Madracis mirabilis and Acropora palmata had few juveniles. This, combined with species characteristics, shows that these species employ very different life history strategies. In some species the abundance of juveniles over the reef paralleled that of larger colonies, but not for example in Agaricia agaricites. The composition of the coral community was apparently no direct function of juvenile abundance. A change in angle of settlement of A. agaricities juveniles with increasing depth, from vertical to horizontal surfaces, seems to reflect the preferred light intensity. The survival of juvenile corals was studied during a 1/2 yr period. One-third remained unharmed, 1/3 died or disappeared and 1/3 was limited in growth by factors such as spatial competition. This was the same for all depths, but factors influencing survival varied with depth.
