Sea Lettuce is a thin flat green algae that normally may reach 45 cm or more in length, though generally much less, and up to 30 centimeters (12 in) across. The plant is found growing attached to cobbles, boulders and bedrock in protected and semi-protected habitats, moderately exposed rocks and shores, in pools and shallow waters near the low watermark, brackish waters and other surfaces using a small holdfast or living in rock pools if it has become detatched. The detatched fronds continue to grow and can create large floating colonies. It thrives in brackish waters, particularly in waters with organic enrichment.
The plant composed of lobed, ruffle-edged leaves that are coarse and sheet-like and resemble a leaf of lettuce. The leaves may appear flat, thin, broad, and often rounded or oval. Its leaves are often perforated with holes of various sizes. Almost no stalk exists at the point of attachment, and no true roots are present. When dried by the sun, its color can range from white to black. Plants tend to be pale green when young, bright green when mature and dark green when old. The chloroplast is cup-shaped in some references but as a parietal plate in others with one to three pyrenoids. There are other species of Ulva which are similar and not always easy to differentiate.
