Illustrations of the 3D surface model of the species Iberolacerta monticola and the morphological traits measured. The ampulla width (a1w, a2w, a3w), length (a1l, a2l, a3l) and depth (a1d, a2d, a3d) are indicated, where a1: anterior ampulla (AA); a2: posterior ampulla (PA); and a3: lateral ampulla (LA). The lengths of the semi‐circular canals (SCs) are illustrated with coloured lines: c1l (green line)–ASC length; c2l (yellow line)–PSC length; and c3l (red line)–LSC length. The following traits are illustrated by different colours: green–ASC; yellow–PSC; red–LSC; blue–utricle; purple–common duct. The utricle and common duct length are indicated with ul and cdl, respectively. Finally, the widths of the three SCs are indicated (c1w, c2w, c3w). ASC, anterior semi‐circular canal; LSC, lateral semi‐circular canal; PSC, posterior semi‐circular canal.
