The ?bulldog-headed zebrafish,? comparing the wild-type (WT, A) and slb mutant (B) embryos at 2 days of development (unpublished photographs, courtesy of Dr. Corinne Houart). (C, D) Basicranial cartilages labeled with Alcian blue, dissected, and laid out as a flat mount, viewed from the dorsal aspect (unpublished, B. Ullmann and C.B.K.); pc, polar cartilage region; a distinctive region of joining between the parachordals and trabeculae. The polar cartilages form as separate elements in some organisms (e.g., see De Beer, 1937; Goodrich, 1930), but probably not in zebrafish. The abbreviations are as in Fig. 1. |
