		Figures   Figure 1. Control embryo at H&H stage 33.   Figure 2. Control embryo at H&H stage 45.   Figure 3. Deceased embryos from the 30 uL ethanol experimental group. Death is most likely attributed to mechanical stress during the de-jellying process.   Figure 4. 50 uM cyclopamine experimental group at H&H stage 33. Note slight truncation in body trunk and tail bud, as well as slight craniofacial abnormalities (compare to Fig.1).   Figure 5. 100 uM cyclopamine group at H&H stage 33. Note body truncation, especially in top subject.   Figure 6. 100 uM cyclopamine experimental group at H&H stage 45. Note underdeveloped gills and severe body and tail truncation (compare to Fig. 2).
