An ontogenetic study of several postembryonic stages of Haplochromis elegans shows that the muscle referred to as "musculus levator externus IV" by previous authors in the adult stage of cichlid fishes is a compound muscle composed of the M. levator externus IV and the central portion of the M. obliquus posterior. Thus the supposed shift of the insertion area of the fourth external levator muscle from the fourth epibranchial to the fifth ceratobranchial, as deduced from adult morphology only… CONTINUE READING
