A scanning-electron microscopic (SEM) study of a clutch of eggs and juveniles of Dickdellia labioflecta on Colossendeis megalonyx megalonyx revealed that the young snails remove the upper layers of the pycnogonid cuticle, most probably by rasping. This way holes are created in the cuticle that could serve as a potential source of food for the snail. Measurements and statistics show that the holes have the same density as the cuticular glands. These glands are spread all over the pycnogonid… Expand
