Irish moss

Floating alga

In wave exposed areas, Irish moss can be torn loose from the bottom, but still retains its ability to grow whilst floating around in the water.
   Sea-urchins like the green sea-urchin and strongylocentrotus droebachiensis, can eat large quantities of bottom-living Irish moss. The plants are usually 2-3 years old when they are eaten or torn away by waves or ice. It is uncommon that they live for more than 4-5 years.
Irish moss
When irish moss recieves little sunlight it is usually dark red in colour, but attains a light yellow or green colour when exposed to stronger sources of light. The white patches at the bottom of the two plants are bryzoas, and the white dots further up are tube building polychaetes.
