Fig. 3

SEM micrographs of the surface topography of the forebody and hindbody of Crepidostomum oschmarini. a Two symmetrical longitudinal fields of papillae (white circles), the protruded cirrus and the ventral sucker on the forebody. b Ciliated and dome-shaped sensory endings in the two longitudinal fields of papillae. c Ventral sucker with 6 dome-shaped papillae on its rim (white circles). d Radially arranged surface corrugations on the rim of the ventral sucker and the dome-shaped papillae. e Dome-shaped papilla (white circle) on the ventral sucker rim. f Posterior extremity of the body with the terminal excretory pore. g Cobblestone-like protrusions of the body surface. Abbreviations: cp, cobblestone-like protrusion; cr, cirrus; dp, dome-shaped papilla; ep, excretory pore; lp, lateral papilla; p, ciliated papilla; pe, elevation around genital pore; tr, transverse tegumental ridges; vs, ventral sucker
