Sea moss, scientifically known as Chondrus crispus, is a type of algae or seaweed. It grows in waters along the rocky Atlantic coasts, primarily between North America and Europe

It's an edible sea plant similar to other seaweeds, algae, and other familiar leafy sea vegetables like kelp or dulse.

Sea moss grows in a number of colors, such as various shades of green, yellow, purple, red, brown, and black.

The most common varieties that grow in the warmer waters are generally red and often called Irish moss.
