Worldwide there are about 50 species of seagrass. Seven seagrass species occur in Florida, and all but one of those can be found in Charlotte Harbor. The three you are most likely to see are Turtle grass, the one with the wide flat blade (leaf), Manatee grass, a long skinny tubular grass found closer to the passes where the water is nice and salty, and Shoal grass, this one’s very fine, with thin flat blades; sometimes you see it exposed at low tides.

Each seagrass species has its own personality, things it likes, things it can tolerate. Shoal grass for instance, has a wide salinity range and can grow in low light conditions. Manatee grass however, has a narrow salinity range and needs high light conditions. And, Turtle grass has a lot of surface area on its blades, making it a favorite place for algae, tube worms, and barnacles to attach.
