Fig. 2. Oral and pharyngeal jaw morphology.

Fig. 2

(A-E) Alizarin red stained, flat-mounted branchial skeleton (A-C) and oral jaw (D-E) from a 6-month-old freshwater adult stickleback. (B-C) Magnified view of left dorsal pharyngeal tooth plate 1 and 2 (B) and the ventral pharyngeal tooth plates (C). (D) Premaxilla (upper or dorsal oral jaw) dentition. (E) Dentary (lower or ventral oral jaw) dentition. (F-H) Tooth plates from Alizarin red and Alcian blue stained 20 days post fertilization freshwater larval stickleback. (F) Left dorsal pharyngeal tooth plate 1 and 2. (G) Ventral pharyngeal tooth plates. (H) Oral jaw containing both premaxillary and dentary dentition. DTP1 = dorsal tooth plate 1, DTP2 = dorsal tooth plate 2, VTP = ventral tooth plate, Mx = maxilla, Pmx = premaxilla, Den = dentary bone. Scale bars = 1 mm (A-C), 500 μm (D-E), and 100 μm (F-H).
