Fig. 6.

Graphical representation of the dentition in representative grilse and salmon. Vertical lines represent tooth positions. Positions are shown from anterior (left) to posterior (right) but are not numbered because of the uncertain presence of anterior positions. In addition, not all positions at the rear end of the row are figured. Horizontal lines connect teeth in a similar stage of development (for replacement teeth) or functionality (for functional teeth). Lingual to the top, labial to the bottom of each chart. (a) Graphical representation of the dentition on the left dentary of a male grilse (cf. Fig. 5b). Legend and color codes as in Figure 4. (b) Graphical representation of part of the dentition on the left dentary of a female salmon (cf. Fig. 5d). Legend and color codes as in Figure 4.
