Location	http://bilbo.bio.purdue.edu/~npelaez/images/100692.JPG
Observations	This seaweed has attached its root like structure into the crevice of the rock of the intertidal zone.
Explanations	Seaweeds are vulnerable to desiccation when exposed during low tide. They attach themselves in crevices to trap moisture. Their thick cell walls also trap moisture for the organism, which is why seaweeds appear slimy and wet.
California Standards	Know organisms depend on their environments Organism survival Specialized structures
