Sea lettuce


Ulva, or sea lettuce as it is more commonly known, is named for its appearance and the fact that it is edible – it is used as a food source in many countries in salads, soups and other dishes. This alga grows in intertidal and subtidal waters, and is commonly found along rocky shores and groynes. Ulva uses its small holdfast to attach to a variety of substrates including reef, rubble, shells, nets and ropes. It is also seen washed ashore, as it is easily dislodged and can be torn during storms. Sea lettuce is an important food source for marine life, including abalone.
