Fig. 2. Microphotographs of Cercaria cattieni 1 stained with Erlich's haematoxylin (A) and Heidenhain's iron haematoxylin (B–I). A – daughter sporocyst; B – underdeveloped cercaria; C – cercaria at late stage of development (tail lost during fixation); oral (os) and ventral (vs) sucker, excretory bladder (ex), primordia of cirrus sac (cs) and uterus (ut) are visible; D, E – spination of the oral sucker (D) and ventral sucker (E) rim (DIC); note sensory papillae (se) on E; F – forebody of cercaria (DIC), caeca (c), cephalic ganglia (cg), oral sucker (os), penetration glands (pg) and pharynx (ph) are visible; G, H – ducts of penetration glands going along the oral sucker, opening near the stylet (st) tip (DIC); I – hindbody of the cercaria (DIC); primordia of ovary (ov) and Laurer's channel (lc) are visible posterior to the ventral sucker (vs); main collecting duct (mcd) starts anterolaterally from the excretory bladder (ex) and goes around testis primordium (te).
