Abstract:
A scanning electron-microscope examination of the scolex of Houttuynia struthionis, a cestode of ostriches,
was undertaken in order to study its surface structure. The scolex differs from those of other
subfamilies in the family Davaineidae in that it does not have scale-like spines covering the base of the
rostellum. Instead, the base is covered with small hooks resembling the larger rostellar hooks in shape.
