DID YOU KNOW …
Most sharks give birth to live young, but a few lay eggs, mostly small sharks that live near the sea floor. Empty egg cases often wash up on beaches and are called mermaid’s purses.

Juvenile Common Egg Cowry (Ovula ovum) covered by it’s mantle.
The surface of the shell is smooth, shiny and completely snow white, with a dark reddish-purple interior, visible through the wide and long aperture, which bears teeth on one side only.
The mantle is black, with a pattern of small white spots in adults, while juveniles resemble some toxic nudibranchs of the genus Phyllidia owing to their orange yellow sensorial papillae. The lateral flaps of the mantle usually hide completely the white surface, but the mantle is quickly retracted into the shell opening when the cowry is disturbed.
I’m laughing more than I should be.
Ba ha ha!
