egg capsule
Protective spawn casing
An egg capsule is a protective case enclosing eggs, produced by certain animals.
Sharks and rays deposit leathery egg capsules often called mermaid's purses.
Snails and other mollusks lay eggs in gelatinous capsules.
The structure shields developing embryos from predators and environmental stress until hatching.
