(Green algae, green seaweeds) Family Ulvaceae. Ruffled sea lettuce Ulva taeniata (Setchell) Setchell & Gardner (Elliston, South Australia, to Walkerville, Victoria, and around Tasmania.

Ulva australis, the southern sea lettuce, is a species of bright green coloured seaweed in the family Ulvaceae that can be found in waters around Australia and was first described by Swedish botanist Johan Erhard Areschoug. It is an edible green algae, although sometimes designated as a seaweed. [1]
Sea lettuce is eaten by a number of different sea animals, including manatees and the sea slugs known as sea hares. Many species of sea lettuce are a food source for humans in Scandinavia, Great Britain, Ireland, China, and Japan (where this food is known as aosa). Sea lettuce as a food for humans is eaten raw in salads and cooked in soups.
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, [1] and grass kelp. [2] Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha .
Ulva lactuca, also known by the common name sea lettuce, [1] is an edible green alga in the family Ulvaceae. It is the type species of the genus Ulva. A synonym is U. fenestrata, referring to its "windowed" or "holed" appearance. Despite its common name, it is not a lettuce. [2]
The San Pedro-based Marine Mammal Care Center is in need of donations and volunteers as it combats an algae bloom that has killed or sickened more than 1,000 creatures.
The Ulvophyceae or ulvophytes are a class of green algae, [3] distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data. [4] The sea lettuce, Ulva, belongs here. Other well-known members include Caulerpa, Codium, Acetabularia, Cladophora, Trentepohlia and Monostroma.
Overgrowing algae bloom at the surface of seawater is an environmental hazard to the coastal underwater biome. Surface algae overextension can block the entry of sunlight below the infected water region, creating a much shallower aphotic zone. The disappearance of sunlight can be fatal for the plants and organisms living below the surface that ...
