Ultrastructure of the cuticle of the chalimus larva of the salmon louse Lepeophtheirus salmonis (Krøyer, 1837) (Copepoda: Caligidae) Naturalis
Bron, J.E.; Shinn, A.P.; Sommerville, C..
The cuticle of the chalimus II stage of Lepeophtheirus salmonis (Copepoda: Caligidae) comprised a four-layered epicuticle with a pronounced fuzzy coat which was separated from the outer and inner procuticles by a layer of transitional procuticle. The cuticle is underlain by a single-layered epidermis which overlies integumental glands and chromatophores. The structure of this cuticle is very similar to that described for free-living copepods and does not display the modifications associated with more highly transformed parasitic species.

Moulting in the chalimus larva of the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae) Naturalis
Bron, J.E.; Shinn, A.P.; Sommerville, C..
The ultrastructure of moulting in the chalimus phase of the parasitic caligid copepod Lepeophtheirus salmonis is described for the first time. The major features of the moult sequence correspond to those of other Crustacea, save for the absence of a distinguishable intermoult as defined by reduced epidermal activity and a cessation of cuticle production. This latter may be explained cither in terms of a continuous moulting process related to the constant food supply available to a parasite or in terms of a highly abbreviated intermoult period. The findings are discussed with respect to studies of other Crustacean species.
