Contributions of Comparative Ultrastructural Research to Problems of Invertebrate Evolution
Department of Zoology, University of Kiel 2300 Kiel, West Germany (FRG)
The contributions of ultrastructural research to the elucidation of invertebrate evolution are discussed by means of a number of selected examples. Studies of the fine structure of the integument of Aschelminthes and Platyhelminthes illustrate the method of interpretation. In addition, the following subjects and their significance for phylogeny are treated: annelid setae, sensilla of Pentastomida, choanocyte-like cells, epitheliomuscular cells, podocytes, gills of Polychaeta and lungs of Decapoda, and spermatozoa
