Dulse seaweed is a type of edible red seaweed that is high in protein.
There are three main types of seaweed algae: green, brown and red. Red seaweed can grow at depths of up to 879 feet, deeper than brown and green seaweed, according to Fact Monster. The red seaweed's pigment, a clear red or purplish color, allows plants to absorb blue and violet light at such depths. Most of the thousands of known species of red algea in the Rhodophyta family are in saltwater, and are common in warm and tropical climates.
