What Is a Sea Urchin?

Sea urchins are small, spiny marine creatures found on ocean floors around the world. Inside their hard, spiny shells (called "tests") lies the edible part, commonly referred to as uni, which is actually the sea urchin's gonads.

Anatomy and Habitat

Shell (Test): The shell is a rigid, spherical structure covered in protective spines.
Spines: These spines serve as a defense mechanism against predators and can move to help the urchin navigate.
Tube Feet: Located underneath the shell, tube feet help sea urchins move and cling to surfaces.

Sea urchins thrive in rocky seabeds, kelp forests, and coral reefs, playing a crucial role in maintaining marine ecosystems by controlling algae growth.

Types of Sea Urchin for Uni

Purple Sea Urchin: Delicate flavor, common in many regions.
Red Sea Urchin: Larger with a richer, more intense taste.
Green Sea Urchin: Sweet, buttery flavor, often harvested in colder waters.

What Is Uni?

Uni refers to the edible gonads of the sea urchin. These golden-orange or yellow lobes are prized for their creamy texture and intense oceanic flavor.
