Anthelia glaucaLamarck, 1816 是一种在夸祖鲁-纳塔尔省发现的雌雄异体、体外孵卵软珊瑚。它在夏季繁殖活跃。夏末产生的配子的发育在冬季停止。在水螅体的基部发现了几个阶段的配子，雌性水螅体在长达 4 至 5 个月的繁殖期内产生多个周期的幼虫。幼虫在独特的咽育育袋中育雏，这是其他珊瑚物种中尚未描述的。育儿袋由扩张的咽部以及胚胎和幼虫近端和远端的收缩组成。我们的数据表明，卵子转移和受精发生在满月时，成熟的幼虫在新月后释放。 A 中不存在虫黄藻。青光细胞，但虫黄藻感染始于未成熟幼虫阶段。
Anthelia glaucaLamarck, 1816 is a gonochoric, external-brooding soft coral found in KwaZulu-Natal. It is reproductively active in the summer months. The development of gametes produced in late summer is arrested in winter. Several stages of gametes are found at the base of the polyps, and female polyps produce several cycles of larvae over an extended breeding period of 4 to 5 months. Larvae are brooded in a unique pharyngeal brooding pouch not yet described in other coral species. The brood pouch consists of an expansion of the pharynx with constrictions proximal and distal to the embryos and larvae. Our data suggest that egg transfer and fertilization occur at full moon and the mature larvae are released after new moon. Zooxanthellae are absent inA. glaucaoocytes, but zooxanthella infestation commences at the immature larval stage.
