kelp2.jpg (75683 bytes) 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.

ENTEROM.JPG (68484 bytes) 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.
