. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. Figure 1. Early development of Pocillopora vermcosa: from unfertilized egg to two-cell stage. (A) Oocyte isolated from the gonad. Zooxanthellae are distributed evenly in the cytoplasm. The germinal vesicle is at the center of the oocyte. (B) Oocyte viewed under epifluorescence (BV excitation). The red fluorescence is due to algal chlorophyll. Cytoplasm of the oocyte exhibits blue-green autofluorescence. (C) Spawned egg. Zooxan- thellae are mainly located in the right hemisphere and lipid droplets in the left hemisphere. (D)

Cleavage furrow (arrow) starts at the hemisphere that contains the /.ooxanthellae. (F) Two-cell stage. Zooxanthellae are divided equally into the two 'ineres. Bars = 100 fim. connected to each other by the contact junctions near the apical surface (Fig. 3B). In other regions of the interface, blastomeres were only loosely attached to each other or were separated by extracellular space. Villi-like cellular processes were observed in the extracellular space, and those from neighboring blastomeres were often intermin- gled (Fig. 3C). When blastomeres in the outer layer con- tained Zooxanthellae, the /ooxanthellae were usually at the lower or lateral margin of the blastomere. Zooxanthellae at the lateral margin of the blastomere bulszed into the extra-.
