FIGURE 2 in Morphology of developing larvae and a dichotomous key for five bubble-nesting Betta species (Teleostei: Osphronemidae)

FIGURE 2. General illustrations of Betta species' yolk sac larvae (A) and juvenile (B) showing morphometric characters and dark pigmentation patterns. Abbreviations of body dimensions: NL = notochord length, SL = standard length, BD = body depth, HL = head length, PreAL = pre-anal length, ED = eye diameter. Abbreviations for pigmentation patterns: a = punctate spot, b = stellate spot, c = longitudinal stripe along dorsal edge of yolk sac, d = faded stripe along ventral edge of tail, e = pre-orbital bar, f = first sub-orbital bar, g = second sub-orbital bar, h = post-orbital bar, I = post-orbital bar, j = pectoral fin base bar, k = dorsal stripe, l = central stripe, m = ventral stripe, n = caudal spot, o = small punctate spots on caudal fin.
