These kelp forests are found in four of our national marine sanctuaries along the West Coast,and are dominated by two species: giant kelp (Macrocystis pyrifera) and bull kelp (Nereocystis leutkeana). Among the fronds in the kelp canopy live bryozoans, hydroids, mysids, amphipods, isopods, crabs, snails, nudibranchs, and juvenile fish of all sorts. The genus is limited in distribution because it reproduces only at temperatures below 18–20 °C (64.4–68 °F). found: Work cat.

Both of these species are found in California waters, however north along the coast in Washington waters bull kelp is predominant. Giant Kelp thrives in 30- 60 feet of water where there is plenty of sunlight and cool/cold ocean currents that bring nitrogen and other nutrients. Because kelps are primary producers that modify the environment to create suitable habitat for a great diversity of species, they are known as foundational species. These seaweeds still have value as seasoning agents, food wrapping, and a source of fibre and vitamins.

Marine grazers such as urchins, fish, and snails can also limit distribution by overgrazing, particularly when predators are removed, which may allow herbivorous populations to boom. What makes this macroalgae unique besides the ability to grow to heights of up to 200 feet, is that there are airbladders known as a pneumatocyst that helps the plant float near the surface and gather more light for photosynthesis while shading out competitors. 6.
