An Introduction to Asparagopsis Armata

“We have lingered in the chambers of the sea

By sea- girls wreathed with seaweed, red and brown



Asparagopsis Armata is one of the marine red algae which have the most elaborate life cycles of all the marine algae. It has two distinct life cycles and they are so different that at one time it was thought to be two different species. Its colour can range from pale pink through to red and bright purple, with bushy, pyramid shaped tufts growing to around 30cm in length in the intertidal and subtidal zones of the ocean.

It is also known as Red Harpoon owing to its harpoon like barbs, which are distinctive to this species of seaweed, allowing them to attach to other seaweeds. The word “armata” means “armed”, and the attachment of asparagopsis armata to other seaweeds and rocks means that it is not easy to harvest, and must be harvested carefully by hand.

Why It’s So good

Like other seaweeds, Asparagopsis Armata is one of the oldest life forms on our planet, rich in vitamins, minerals and amino acids, and according to is ” a powerful antioxidant with antibacterial properties and is a valued ingredient in many cosmetic products”.

It does not have a root system and thrives in response to the high environmental stress factors of its habitat by taking its nutrients directly from the ocean, absorbing and concentrating them so that this beautiful and ancient life form contains up to 10 times more nutrients than any plant on land.
