Seaweed, Kelp and Seagrass, what’s the difference?
Beloved child has many names and sometimes it can be difficult to know what is what.
Seaweed and Kelp are macroalgae. In Norway there are 450 species, these are divided into 3 groups
Brown algae: Sugar kelp (kombu), winged kelp (wakame), rock weed, Sagtang, Bladder weed.
Red algae: Dulse, Nori, Truffle seaweed
Green algae: Sea lettuce and Intestinal Green (belongs to the plant kingdom, but is referred to as algae).
You can think of the shoreline as a greenery garden with different species that are all edible. As land greens, they have different tastes, looks, textures and qualities. Algae poison from microalgae in mussels does not poison Seaweed in the same way. When collecting seaweed, we use the outermost and newest part that has not accumulated foreign substances
Seaweed species grow on stone by the shores. Like flowers, they grow the newest part from the tip.
Sea kelp are the larger algae you will find at the bottom of the shore and in the sea. It grows like a strand of hair from the attachment up to the light.
The macroalgae lack roots, but fastens against the stones.
Seagrass is a plant that has adapted to marine life and puts its roots on soft sand/stone and shallow water. There are about 60 species in Norway. Eel grass is the most common and can be found along the entire coast.
