Rock pool in the high intertidal zone.
Nereocystis, also called Bull Kelp, is an important part of the kelp forest. It forms thick beds on rocks. The blades are long and narrow. It is an annual kelp and is found from Alaska to central California.
Macrocystis pyrifera, or giant kelp, is found in many locations around the world and is dominant here in southern California. The sporophyte life cycle is most seen for this species. It can grow 2 feet a day and be as long as 160 feet in its lifetime. It is made up of brown algae. It thrives in colder water conditions.
Growing all over the rocks and exposed at the mid - low tide. I know this looks like red in the photos - must have had the wrong setting on the camera as this was brown! *LOL*
