ABSTRACT

The first morphological examination of the surface and internal anatomy of the kinorhynch, Echinoderes dujardini was undertaken using the scanning and transmission electron microscopes. The oral styles and at least the first ring of scalids were found to have a basal pectinate fringe that resembles the pectinate fringe found at the posterior margins of the trunk segments. In addition to the fringe, the scalids were subdivisible into at least two distinct classes which are similar in structure to the trichoscalid and type I spinocalid identified by Moritz and Storch in T. giganteus. The trichoscalid of E. dujardini however, was found to possess a unique fluted cuticle structure with spines arising only on the medial surface. Although pores are known to occur in the cuticle of homalorhagid kinorhynchs, such pores were not found in the cyclorhagid, E. dujardini. A structure, provisionally designated “sensory-like structure” is described. Some 60 or more compactly placed spines occur as paired circles or ellipses on all but the terminal trunk segment. An electron dense structure was seen in the subsurface of the placids that may lend mechanical support and may contribute to the “Napoleon hats” seen with light microscopy. Micrographs of the circumentric nerve ring, gut, epidermis and pharynx are presented. Located at the anterior of the pharynx is a peripharyngeal muscle. The muscle, composed of two membrane bounded smooth muscle strands, probably acts as a sphincter to prevent a reverse flow of food material. Finally, scanning micrographs show a single opening located dorsolaterally on the 10th segment. This opening has been interpreted as an excretory pore even though it does not occur ventrolaterally on the 11th segment as reported for other kinorhynchs. More... »
