Evaluations indicated that our procedure is capable of extracting phylogenetic information from morphometric data. KEY WORDS: morphometric data, phylogeny, PCA, haplochromines, cichlids.

Of 73 East-African, lacustrine cichlid species the parameter value sets were plotted in the evaluated morphospace where these species-specific sets appear to be located in a narrow zone around the border between optimal and suboptimal sets but quite far

It can be assumed that good photopic sensitivity is a necessity to deal with demands from the light environment
