egg shell
chorion (an embryonic membrane, elaborated by the follicle cells, which encloses the egg. The eggs of truly viviparous fishes are non-chorionated. Usually hardens on contact with the water; after fertilization the egg secretes fluid and shrinks inward leaving a perivitelline space. May lie external to the zona radiata. Called egg shell in fish)
