Researchers have recently discovered 20 new species of Sea lettuce along the Baltic and Scandinavian coasts.
About Sea Lettuce:
Sea lettuce (Ulva lactuca) is commonly referred to as seaweed.
It is a genus of green algae usually found growing on rocky shores of seas and oceans around the world.
Some species of Sea lettuce also grow in brackish water rich in organic matter or sewage and can accumulate heavy metals.
It usually grows attached by a small discoid holdfast to rocks and shells, but it can also grow in a free-floating, non-attached form, sometimes in prolific masses.
It needs a lot of sunlight to flourish.
It is perennial, and grows all year, although the largest blooms occur during the summer.
Large masses of sea lettuce are often an indicator of nutrient pollution in the water.
In some parts of the world, people eat sea lettuce in soups and salads.
Features:
It resembles leaves of green lettuce. The color is often bright green but can range from dark green to almost yellow.
The leaves can be narrow or broad and single or multi-lobed. They’re often rounded or oval with ruffled edges and riddled with holes or perforations.
