Abstract: Morphological variants of Cichla temensis, readily differentiated by their striking color pattern differences, are found in several Amazon basin flood pulse river systems. The adult variants have at times been thought to represent different species or sexual dimorphism. A three part study was performed in two regions in Brazil (rio Igapó Açú and rio Caures) to elucidate the nature of the variants. In part one; selected diagnostic morphometric characters were compared intraspecifically among the variants and in… Show more

“…The morphological variation within C. temensis was previously attributed to assumptions that the variants were different species, subspecies or an effect of sexual dimorphism (Braga, 1953;Myatt et al, 2005;Kullander & Ferreira, 2006). A recent study has shown that the variants are all members of the same species and the differences in color and pattern among the variants are due to individual fish cycling through a series of changes correlated to seasonal gonad maturity (Reiss et al, 2012).…”

“…Although color pattern variation occurs along a continuum, the common names used to describe the variants are based on the two distinct extremes (Winemiller, 2001;Reiss et al, 2012). The more brightly colored variant is known within the English-speaking sportfishing community as the Three-barred Peacock Bass (Myatt et al, 2005) and in Brazil as tucunaré açu (açu) (Kullander, 2003).…”
