| Abstract | ||
| Lernanthropus kroyeri (Copepoda, Siphonostomatoida: Lernanthropidae), a parasitic crustacean from the gills of Dicentrarchus labrax, was abundant at higher spring and summer temperatures. Accordingly, the opportunity was taken to throw light on some morphological adaptations with the aid of scanning electron microscopy to clarify the possible functions of these structures. several kinds of tegumental structures were identified on the body surface, among which the tubular and filamentous forms were the most dominant. These tegumental components seem likely to provide the parasitic copepod with an increase of the surface area for better integumental respiration. SEM observations also revealed the existence of longer and more diverse tegumental components, which are probably involved in sensory functions of the tegument. Moreover, uniciliated sensory formations were recognized regularly across the whole tegumental surface, except on the antennae and maxillipeds. These sense organs show marked variability in distribution and morphology. | ||
