FIGURE 2. A) Schematic drawing of an Aphanius scale, including some of the terms used in this study. Terminology follows Lippitsch (1990), Kuusipalo (1998), Jawad (2005) and Jawad and Al-Jufaili (2007). Dashed lines delimit the different fields. Scale bar: 200 µm. B) Measurements of scale length and width (after Esmaeili 2001). C) Schematic shapes of scale and focus as described in this study and in Table 3; terminology follows Kuusipalo (1998): a—Pentagonal, b—Elliptic-pentagonal, c—Round-pentagonal, d—Round-triangular, e—Elliptic-rectangular, f—Oblong, g—Oval, h—Round, i—Quadrangular, j—Rectangular, k—Trapezoidal, l—Elliptical.
