Where the bottom is rocky and affords places for it to anchor, giant kelp forms extensive kelp beds with large "floating canopies". [8] When present in large numbers, giant kelp forms kelp forests that are home to many marine species that depend upon the kelp directly for food and shelter, or indirectly as a hunting ground for prey. Both the ...
An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
Just one example is the giant bull kelp Nereocystis luetkeana, which have evolved to change blade shape in order to increase drag in water and interception of light when exposed to certain environments. Bull kelp are not unique in this adaptation; many kelp species have evolved a genetic plasticity for blade shapes for different water flow ...
The Giant Kelpfish is a species of clinid, native to the west coast of North America. It is found most commonly in the warmer waters of Point Conception, California, to southern Baja California. It inhabits rocky areas with dense canopies of microalga, giant kelp and other large seaweeds. It is also known that they may use Eelgrass or Surfgrass ...
Urchins have hurt both species, though giant kelp forests have fared better. Some believe the only way to restore kelp is to reduce the purple urchins, which can go dormant for years only to ...
Zooplankton can reproduce rapidly, their populations can increase up to thirty per cent a day under favourable conditions. ... Giant kelp is a foundation species for ...
For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; for example, a wasting disease in predators of purple urchins has led to an urchin population surge which has destroyed large kelp forest regions off the coast of California.

A form of flowering plant that far exceeds Pando as the largest organism on Earth in area and potentially also mass, is the giant marine plant, Posidonia australis, living in Shark Bay, Australia. Its length is about 180 km (112 mi) and it covers an area of 200 km 2 (77 sq mi). [8] [9] It is also among the oldest known clonal plants.
