Figure 3. Adult zebrafish pharyngeal teeth. (A) A lateral view of individual pharyngeal teeth displays the pulp cavity (pc), dentin (d), and enameloid (e) surface, which closely resemble those of mammalian teeth. (B) SEM images display the organization of the three rows of ventral (V), mediodorsal (MD), and dorsal (D) rows of adult teeth. Higher magnification (C) reveals organized dentin tubules and enameloid surface. (D) Sagittal section of 11 adult pharyngeal teeth present on one ceratobranchial 5 arch.
