The distinction of C. acutus from C. propinquus is not an easy task due to the great morphological similarity between both species, particularly when they are at the same developmental stage. This becomes particularly complicated when the individuals are copepodites of the first developmental stages. Consequently, observations about the morphology of both species, such as those focused on the different length of antennae 1 and shape of the prosome’s cephalic segment (rounded in C. propinquus and pointed in C. acutus) become useful tools for the identification of individuals of the two species. However, comparative analyses of the morphology of the different developmental stages are still pending. In view of the above, the aim of the present study was to describe and to compare the morphological features of all the developmental stages of C. acutus identification of individuals of the two species.
