Ulva lactuca is a thin, flat, green alga that is very common on rocks and on other algae in the littoral and sublittoral on shores. It is mostly found in areas where nutrients is abundant. Large amounts of Ulva lactuca are washed up on shores of beaches, where their decay produces methane, hydrogen, sulphide, and other gases. Ulva lactuca may reach 18 cm or more in length, but usually it's less. The membrane is two cells thick soft and translucent and it grows attached to what ever it is growing on. The chloroplast shape of this organism is cup-shaped with 1-3 pyrenoids. Ulva lactuca also known as sea lettuce appears what ever the season is but it is very abundant in the summer. They have ruffed edges and have a slim texture. When sea lettuce dies, bacteria feeding on the decomposing sea lettuce use up a lot of oxygen in the water. This decreases the amount of oxygen for other species.
