DAPI-labeled copepod crustaceans viewed with epifluorescence microscopy and DAPI optics (377-nm excitation; 447-nm emission). a Molted exoskeleton of a fifth-stage harpacticoid copepodite (L’Atalante lower halocline, 611c14). b Intact fifth-stage harpacticoid copepodite (Discovery lower halocline, 609c14). c Mid- to late-stage cyclopoid copepodite (Discovery lower halocline, 610c9). Note lack of strong DAPI signal in all but appendages of (c). Scales: a, c = 100 μm; b = 200 μm
