Sea Lettuce

Sea lettuce is common worldwide on sea shores and shallow sublittoral areas growing in a wide range of conditions and habitats and Lundy is no exception.

Its frond is a bright green flat sheet, translucent in appearance and often split or divided with a wavy edge.  In general it is shorter on exposed shores and on sheltered ones can grow much longer.  Grazed by numerous animals on the shore it is often seen on the sea floor detached and in tatters providing other animals an opportunistic meal.  The sea weed reproduces by releasing gametes from some cells, and it can also spread vegetatively by regeneration of small fragments.
