Hemolymph responses of Alaskan king crabs to rhizocephalan parasitism
Hemolymph from three king crab species, red (Paralithodes camtschatica), blue (P. platypus), and golden (Lithodes aequispina), parasitized by the rhizocephalan Briarosaccus callosus was examined for parasite-induced changes. Protein, hemoglobin, hemocyanin, and glucose concentrations, hemocyte count...
