Algae: Shoreline Plant

Algae are a characteristic plant of the beach. Algae lives on rocks
and between the grains of sand and occasionally adds a green, gold,
pink or purple tint to the sand.

Other plants like Ulva (sea lettuce), manatee grass,
and sargassum (a brown algae or seaweed) are often washed up
onto the beach. The wrack line or strand line is a line of debris that
often runs parallel to the water’s edge and marks the high tide
line. This wrack, though unsightly, is important. It provides an ideal
environment for microorganisms, amphipods and insects.
