Each blade can grow up to 10 m (33 ft) long, and blade growth can reach 15 cm (5.9 in) per day. Nereocystis grows in areas where Pterygophora californica also inhabits. Bull kelp will often grow on the stipe of Pterygophora, with up anywhere from 10 to 20 individuals of Nereocystis attaching to a single Pterygophora stipe. [6]
Bull kelp is a common name for the brown alga Nereocystis luetkeana which is a true kelp in the family Laminariaceae. Species in the genus Durvillaea are also sometimes called "bull kelp", but this is just a shortening of the common name southern bull kelp .
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 ...

Durvillaea bull kelp grow within intertidal and shallow subtidal areas, typically on rocky wave-exposed coastal sites. [15] D. antarctica and D. poha are intertidal, whereas D. willana is subtidal (to 6 m depths). [18] Intertidal species can grow at the uppermost limit of the intertidal zone if there is sufficient wave wash. [19]

Northern kelp crabs are known for their association with kelp and their similar coloration. Their long many-jointed legs have evolved to help them climb bull kelp and also provide help climbing man-made pilings. These crabs are also common in lower intertidal zones in beds of algae or eelgrass. They may also be found under rocks or shelters at ...
