High particle velocities around sinking and swimming D. cxcentricus embryos are shown in Figure 6. Swimming embryos produced a steep velocity gradient: maximum par- ticle speed diminished rapidly with distance from the em- bryo surface. Sinking embryos produced a gentler velocity gradient that disturbed the water column at a greater dis- tance from the moving embryo. Oxygen deprivation had few significant effects on em- bryo development when embryos were reared in low-oxy- gen environments from the time of fertilization. A random- ized blocked ANOVA (SYSTAT Systat Software Inc.) showed significant effects of sample time on embryo length parallel to the animal-vegetal axis (df = 4. F = P - ), but no effects of oxygen treatment (df = 2. F , P = ) (Fig. 7A). The same ANOVA model showed significant effects of oxygen treatment on length perpendicular to the animal-vegetal axis (df = 2, F == , P = ; Fig. 7B). but the spread of mean values (aver-.
