The morphology of the hooks ofEchinococcus granulosus at the protoscolex level was studied by means of scanning electron microscopy. Hooks were uncovered in situ and also freed from the rostellum so as to study them in detail. There were two types of hooks: those of the upper row, which were larger and had a projecting, rounded stout guard, and those of the lower row, which were smaller and had a flattened guard. These and other differences in the morphology of the two types of hooks were studied and related to the differences in their function.
