|Evolutionary morphology of body elongation in teleosts: aspects of convergent evolution|
Schepper, N. (2007). Evolutionary morphology of body elongation in teleosts: aspects of convergent evolution. PhD Thesis. Universiteit Gent: Gent. 2 volumes pp.
This dissertation has focussed on a targeted selection of species that are convergent in having an elongate body. The central aim of this study was to identify how a whole set of structural modifications in the morphology of elongate clariid catfishes are related to different components such as (1) miniaturized head, (2) a special fossorial lifestyle, (3) the presence of hypertrophied jaw muscles and (4) anguilliformity. Therefore, a functional-morphological component analysis, attempting to decouple these four components, has been performed, with Channallabes apus, chosen as the reference species for the elongate clariids.
