Editing Tide pool (section)

===Flora===
Sea palms (''[[Postelsia]]'') look similar to miniature [[Arecaceae|palm trees]]. They live in the middle to upper intertidal zones in areas with greater wave action. High wave action may increase nutrient availability and moves the blades of the [[thallus]], allowing more sunlight to reach the organism so that it can photosynthesize. In addition, the constant wave action removes competitors, such as the mussel species ''[[Mytilus californianus]]''.

Recent studies have shown that ''Postelsia'' grows in greater numbers when such competition exists; a control group with no competition produced fewer offspring than an experimental group with mussels; from this it is thought that the mussels provide protection for the developing [[gametophytes]].<ref name="seasonalpatterns">

Coralline algae "Corallinales" are predominant features of mid and low intertidal [[tide pools]]. [[Calcium carbonate]] (CaCO<sub>3</sub>) takes the form of calcite in their cell walls providing them with a hard outer shell. This shell protects from herbivores and [[desiccation]] due to lack of water and evaporation. Many forms of the Coralline algae bring herbivores, such as mollusks "Notoacmea", to the tide pools during high tides, increasing the biomass of the area. Once low tides comes, these herbivores are exposed to carnivores in the areas, fueling the food web.<ref>{{Cite journal|last=Padilla|first=Dianna K.|date=1984-07-24|title=The importance of form: Differences in competitive ability, resistance to consumers and environmental stress in an assemblage of coralline algae|url=https://dx.doi.org/10.1016/0022-0981%2884%2990213-2|journal=Journal of Experimental Marine Biology and Ecology|language=en|volume=79|issue=2|pages=105–127|doi=10.1016/0022-0981(84)90213-2|bibcode=1984JEMBE..79..105P |issn=0022-0981|url-access=subscription}}</ref><!-- Possibly add a section here about how climate change has affected marine life.
