Sea lettuce ulva lactuca

Sea Lettuce is an edible green seaweed / algae that’s found worldwide, and is also known as Green Laver, Ulva or Ulva lactuca, lactuca being Latin for “lettuce”.

Sea lettuce – Ulva lactuca has a thin and flat leafy-like appearance with ruffle-edges. Being only 2 cell layers thick it is translucent, but surprisingly strong. The plant is a pale green colour when young, becoming a vibrant bright green when mature and turning dark green when old.
The Sea Lettuce plants grow attached, without a stipe, to rocks, gravel, reef flats, shells and other seaweeds by a disc shaped root-like holdfast. I can also be found free floating in the sea. The fronds within the water resemble lettuce leaves, hence the name Sea Lettuce. The plant can grow up to 45 cm long and 30 cm across.

Being mainly a shallow water seaweed, it is found on sheltered and intertidal exposed rocks and shores, and in stagnant tide pools and shallow waters near the low watermark, but has been recorded at depths of 75 feet or more. It thrives in brackish waters, particularly in waters enriched with organic nutrients, but can thrive in moderate levels of nutrients. It is fairly common along the Irish Shoreline and in temperate and colder seas. Sea lettuce is a perennial plant and grows new fronds each spring, but it can be found all the year round, growing best during the summer months because of longer daylight hours and the water temperature becomes ideal for rapid reproduction.

Large volumes of sea lettuce often thrive in areas that are nutrient enriched from sewage outfalls and other farming run-off pollutants that get into streams and rivers. It is a good indicator species to monitor as it grows where there are of high levels of pollutants that would suffocate many other aquatic plants.

The Okinawa Centenarian Study found that the residents of Okinawa are 82 percent less likely than the average American to suffer from coronary heart disease.
