What Is Seaweed

Seaweed is one of those things that you probably don’t think about too often, even if you live near the ocean. But this humble plant plays an essential role in marine ecosystems, providing food and shelter for various marine animals.

Seaweed also has a long history of being used as a food source by humans. Some estimates suggest that we have been eating seaweed for over 10,000 years!

Seaweeds come in all shapes and sizes, from the tiny algae that form on the ocean’s surface to the giant kelp that can grow up to 100 feet in length.

Although they look very different from land plants, seaweeds are more closely related to mushrooms and other fungi (see also ‘Are Truffles Vegan?‘) (see also ‘Are Truffles Vegan?‘) (see also ‘Are Truffles Vegan?‘).
