|Another clump of the unidentified red stuff. It is probably a plant because it is not calcified. It may be a red alga. There are four types of algae: blue-green, green, brown and red. All of these are found in the Cove. Red algae grow mainly below the inter-tidal zone, and wash into the beach.|
This is the forest plant that Carol and Phil Adams talk about in their wonderful Adventures With Nature walk: Sea Otters and The Forest.
|Sea Lettuce/Ulva, two cells thick.|
|Enteromorpha. Feel it. It is slippery. Many water plants are slippery. This helps prevent tearing of the plant when the leaves get tangled.
Enteromorpha is a green alga, that somewhat resembles link sausage in shape. During the day, oxygen bubbles form inside it, a by-product of photosynthesis. You may cut a one inch strand and carry it to the Museum in a Petri dish with a drop of seawater, to look at under the microscope.
The walls of the oxygen chambers are said to be only one cell thick.
