(A) mean number of black crescents, (B) mean number of double swords, (C) mean relative orange area on the caudal fin, (D) mean relative thickness of caudal peduncle; error bars represent minimum and maximum values for A, B and C, and standard error for D. Cariaco drainage populations are underlined.Back to article page
