Development of self-fertilized gametes of the anemone <i>Aiptasia diaphana</i> (scale bars = 10 µm).

(a) Released non fertilized oocyte (SEM). (b) late cleavage stage showing asynchronous “chaotic” cleavage (SEM). (c) Blastula from animal pole perspective, note small micromeres. (c') Blastula from the vegetal pole perspective, showing large yolky macromeres at the vegetal pole (SEM). (d) Prawn chip stage. (e) Gastrula. The blastopore is marked by an arrow. (SEM). (f) Swimming planula, nematocysts marked by arrowhead (light micrograph).(a) 分离得到的未受精卵母细胞（扫描电子显微镜，Scanning Electron Microscope）。(b) 晚期卵裂期，可见异步“紊乱”式卵裂（扫描电子显微镜）。(c) 动物极视角下的囊胚，可见小型小卵裂球（micromeres）。(c') 植物极视角下的囊胚，可见植物极处富含卵黄的大卵裂球（macromeres）（扫描电子显微镜）。(d) 虾片期。(e) 原肠胚，胚孔（blastopore）以箭头标注（扫描电子显微镜）。(f) 游动浮浪幼虫（planula），刺细胞（nematocysts）以箭头头标注（光学显微照片，Light Micrograph）。
