On the evenings of June 11 and 12, 2019, 5 and 6 days before full moon, broadcast spawning by four echinoderm species and two mollusc species was observed on the Marsa Shagra reef, Egypt (25° 14′ 44.2" N, 34° 47′ 49.0" E). Water temperature was 28 °C and the invertebrates were observed at 2–8 m depth. The sightings included a single basket star Astroboa nuda (Lyman 1874), 2 large Tectus dentatus (Forskal 1775) sea snails, 14 individuals of the Leiaster cf. leachi (Gray 1840) sea star and 1 Mithrodia clavigera (Lamarck 1816) sea star, 3 Pearsonothuria graeffei (Semper 1868) sea cucumbers, and 2 giant clams, Tridacna maxima (Röding 1798). The observations presented here provide relevant information on broadcast spawning of non-coral invertebrate taxa in the Red Sea, where spawning is considerably less well documented than in other tropical geographical regions such as the Indo-Pacific and Caribbean.

在2019年6月11日至12日晚上，即满月之前的5天和6天，在埃及的玛莎沙格拉礁观察到了4种棘皮动物和2种软体动物物种的繁殖产卵（北纬25°14′44.2“，北纬34°47 '49.0“ E）。水温为28°C，在2-8 m的深度观察到无脊椎动物。目击者包括一只篮子星阿斯特罗波亚·努达（Lyman，1874年），2只大直齿特克塔斯（Forskal，1775年）海蜗牛，以及14名Leiaster cf个体。leachi（灰色1840）海星和1 Mithrodia clavigera（Lamarck 1816）海星，3 Pearsonothuria graeffei（Semper 1868）海参和2个大蛤，Tridacna maxima（罗丁，1798年）。此处介绍的观察结果提供了有关红海非珊瑚无脊椎动物类群的广播产卵的相关信息，那里的产卵远少于其他热带地理区域（如印度太平洋和加勒比海地区）的文献记载。
