Fig. 1 in Are copepods secondary hosts of Cycliophora?

Fig. 1 Cycliophoran life cycle stages attached to harpacticoid copepods; light micrographs. a Two Symbion sp. feeding stages (fs1–2) attached, respectively, to the metasome and the urosome of a copepod host. The anterior region of the copepod (co) is facing left. The insert figure shows a close up of the trunk of one of the feeding stages with several wrinkles (arrowheads) on the cuticle. b Undetermined cycliophoran stage (ucs) settled on the urosome of a copepod host (co). The anterior of the copepod is facing right. c Same cycliophoran life cycle stage as shown in b, but detached from the copepod host. Note the folded cuticle on its most posterior region. The insert figure shows a close up of the attachment disk that characterizes the most anterior region of this cycliophoran stage. an antennule, as anal somite, ce cephalothorax, cr caudal rami, ds double-somite, ey eye, pc posterior folded cuticle, sl swimming legs
