Figure 10

Schematic comparison of representatives of the four major cladoceran groups. The coloration and the orientation are adapted according to the quadrants of the 4-cell stage in Figures 7 and 8 in order to simplify the comparison, with A - yellow, B - red, C - green, D - blue. Dark blue - ncr. Connecting lines indicate sister cells, double arrows indicate the direction of divisions during the subsequent division. A-A”’ The four consecutive division cycles of Leptodora kindtii starting with the fourth division in A (after [50]). The cell lineage was not traced in [50], however, the pattern of the two interlocking cell bands is indicated here by gray versus white filled energids. B-B”’ The four consecutive division cycles of Holopedium gibberum after [3, 39] starting with the third division in B. B View of the animal pole presenting the AC cross furrow. B’-B”’ View of the vegetal pole. C-C”’ The four consecutive division cycles of Bythotrephes longimanus starting with the third division in C, all views of the vegetal pole. D-D’” The four consecutive division cycles of Moina rectirostris after [52] starting with the 4-nuclei stage in D. D Lateral view of the D quadrant with the animal pole facing down. D’ Lateral view of the A and D daughter cells with the animal pole facing up. D”-D”’ View of the vegetal pole.
