egg cases
Protective spawn housings
Egg cases are protective structures that enclose eggs, produced by various animals.
Sharks and rays deposit leathery pouches called mermaid's purses.
Insects like mantises and cockroaches create hardened foam cases called oothecae.
The term applies broadly to any natural casing that shields developing eggs: We found empty egg cases washed up on the beach.
