Ulva lactuca
Ulva lactuca, more commonly known as sea lettuce, is a thin flat green alga growing from a discoid holdfast. Individual blades can grow to be more than 400mm in size. It can attach to rock via a small hold-fast, so as to survive regular tides. They have smooth waxy leaves which helps to retain water. Therefore, it is also important for organisms living in coastal areas where the salt from the sea water causes many organisms to be dehydrated.
