Abstract

The endoskeleton of the calanoid copepod, Calanus finmarchicus, and its muscle attachments were described by Lowe (1935). She reported that the endoskeleton in C. finmarchicus consists of two tendinous endosternites and chitinous exoskeletal ingrowths to which muscles are attached. Howse (1960) noted attachments of the main muscles of the thorax to the exoskeleton in Acartia tonsa.

Bouligand (1962) described the ultrastructure of muscle attachments to cuticle in three species of freshwater copepods of the genus Cyclops. Raymont et al. (1974) described the fine structure of muscle attachments to cuticle in C. finmarchicus.

Information of the internal anatomy of marine copepods remains sparse. Therefore, we thought it worthwhile to focus our observations on the attachments of muscle to exoskeletal ingrowths in A. tonsa.
