The infestation and dispersion patterns of Carcinonemertes spp. (Nemertea) on their crab hosts
Seasonal changes in the infestation and dispersion patterns of egg predatory nemerteans on their crab hosts were analyzed. Marked differences in the seasonal patterns of infestation were noted between worm species, yet, common patterns in the aggregation of the worms were found. Worm aggregation inc...
