Despite its appearance and use of photosynthesis in chloroplasts, kelp is technically not a plant but a stramenopile (a group containing many protists). [4] Kelp grow from stalks close together in very dense areas like forests under shallow temperate and Arctic oceans. [3]
Macrocystis is a monospecific genus [3] of kelp (large brown algae) with all species now synonymous with Macrocystis pyrifera. It is commonly known as giant kelp or bladder kelp. This genus contains the largest of all the Phaeophyceae or brown algae. Macrocystis has pneumatocysts at the base of its blades.
Rockfish swimming around giant kelp A diver in a kelp forest off the coast of California A kelp forest off of the coast of Anacapa Island, California Giant kelp uses gas-filled floats to keep the thallus suspended, allowing the kelp blades near the ocean surface to capture light for photosynthesis. The architecture of a kelp forest ecosystem is ...
Brown algae including kelp beds also fix a significant portion of the earth's carbon dioxide yearly through photosynthesis. [57] Additionally, they can store a great amount of carbon dioxide which can help us in the fight against climate change. [58]
Nereocystis (Greek, 'mermaid's bladder') is a monotypic genus of subtidal kelp containing the species Nereocystis luetkeana. [1] Some English names include edible kelp, bull kelp, bullwhip kelp, ribbon kelp, bladder wrack, and variations of these names. [2]
Ecklonia maxima, or sea bamboo, is a species of kelp native to the southern oceans. It is typically found along the southern Atlantic coast of Africa, from the very south of South Africa to northern Namibia. In these areas the species dominates the shallow, temperate water, reaching a depth of up to 8 metres (26 ft) in the offshore kelp forests ...
Pleurophycus gardneri is a habitat to many species of amphipod, and most commonly supports species specific to stipe burrowing. [2] Amphipods decrease the lifespan of this kelp due to damages caused by burrowing; any breaks in the plants' holdfast up to its stipe will kill the plant, hence its heightened mortality rate due to stipe burrowing amphipods.
Egregia menziesii is a species of kelp known commonly as feather boa kelp. It is the only species in the monotypic genus Egregia . It is native to the coastline of western North America from Alaska to Baja California , where it is a common kelp of the intertidal zone .
