Seagrasses
World wide there are 7000 estimated seaweeds, 4000 microalgae and 50 seagrasses. Here in the Pacific Northwest we have an estimated 700 of these species making our area one of the richest in seaweed biodiversity in the world. (Harbo, 1999)

Seagrasses are flowering plants that have adapted to live in salt water environments. You will find sea grasses in areas of soft substrate, and surf grasses will be found on the surf beaten, rocky areas. Both have roots that have adapted to keep them in place. |
