FUNCTIONAL MORPHOLOGY OF THE HEAD OF THE PERCH (PERCA FLUVIATILIS L.): AN ELECTROMYOGRAPHIC STUDY by J.W.M.OSSE (zoological Laboratory, University of Leiden, The Netherlands) 290 . I. INTRODUCTION At first glance, a mounted skeleton of a teleost fish shows a complicated array of little bones with complicated shapes and a large number of joints between them. By comparison, the skull of a mammal is a solid 291 structure. One's first impression of complexity is reinforced when one realizes that these bones form only part of the construction of the head of a living fish. Since every complexity raises a number of fascinating problems, the study of the functional morphology of such a head is an absorbing although hazardous enterprise. Functional morphology can be defined as the description of the dynamic interrelationships of the parts of an organic whole. It can be studied by using adult specimens, ontogenetic stages, etc. The results can be arranged in a pattern showing the interrelations of the elements, i.e., a description of the architecture. The study of functional morpholo- gy can also yield a better understanding of the selective forces involved in the evolution of a given species as well as the result of
