Figure 4From: Reproductive natural history and successful juvenile propagation of the threatened Caribbean Pillar Coral Dendrogyra cylindrus Early development of D. cylindrus. Shown are one unfertilized egg and three developing embryos at the eight-cell stage. Fertilized zygotes underwent holoblastic, equal cleavage through the 16-cell stage. The mode of gastrulation was not observed. Early cell divisions occurred at approximately 40Â minute intervals. Embryos developed into swimming larvae in less than 16Â hours. Scale bar represents approximately 0.5Â mm.Back to article page
