FIGURE 4. Diversity of Lagenophrys spp. Intraspecific variation and adaptation for attachment to setae. A, B. Two morphs in a population of L. machaerigera that represent the extreme range of variation in outgrowth of the anterior lip of the lorica aperture and thickening of the posterior lip. C. Dorsal view of L. lenticula, which attaches to setae of the amphipod Hyalella with a posterior prolongation of the lorica (Ps, pseudostalk). D. Dorsal view of L. vaginicola, which attaches to caudal setae of harpacticoid copepods. A, from Clamp 1992; B–D, from Clamp 1991. All scale bars = 10µm.
