TOWARDS A CONSTRUCTIONAL MORPHOLOGY OF CICHLID FISHES (TELEOSTEI, PERCIFORMES) by C. D. N. BAREL (Researchgroup Ecological Morphology, Zoölogisch Laboratorium, Rijksuniversiteit Leiden, P. O. Box 9516, 2300 RA Leiden, The Netherlands) SUMMARY Based on ca 100 lacustrine cichlid species and following a holistic procedure of func- tional morphology, this paper analyses what constraints spatial relations of structures may set on the compatibility of functions. Among the many feeding behaviours of cichlids two groups are distinguished: (1) those in which powerful biting with the oral jaws are involved and (2) those in which the food is directly sucked into the buccal cavi- ty without prior manipulation by the oral jaws. Related to the core functions "biting" and "sucking only" two types of oral jaw apparatuses (OJA) are distinguished and compared (i. e. comparison in a functional context). Taking the head as the available space (constructional component) it is subsequently investigated what spatial demands there are to accommodate these two types of OJA together with other apparatuses (com- parisons in a constructional context), and how these spatial demands 'affect' the func- tion of the other apparatuses, especially the expansion apparatus (EA) and outer head shape (OHS, part of the locomotory apparatus).
