Which Parasite Eggs Have Operculum?

The eggs of a fluke typically have brown shells and a small cap, called an operculum, from which the enclosed larval larva escapes.

Which egg has the operculum?

Operculum = Egg cap from which larvae emerge from the egg. A term specific for trematode ova.

What is operculum egg?

The operculum is an empty cavity. The chitinous fibers of the egg-shell in this area are diffuse and loose, with numerous micropores or spaces. The egg-shell in this area therefore appears to form a fine tubular network. The oocyte is an undifferentiated cell with a biconcave drum-like shape.
