How does kelp attach to the ocean floor?
The kelp attaches itself to the ocean floor, a rock, or another hard surface through the use of the holdfast, or a root-like structure that emerges from the base of the kelp. Some kelp species, such as American species, also have gas-filled bladders that keep the fronds afloat in the water, allowing the kelp to create its distinctive forest-like structure.

These include other algae, fish, and invertebrates. Other creatures, like marine mammals and birds, utilize kelp forests as sources of food. Some of the most commonly found invertebrates are prawns, snails, and brittle stars. Some of these species spend their whole lives in kelp forests, living, breeding, and dying there. At the same time, others use them only as a nursery, a place that provides increased protection for their young while they are most vulnerable. Predators are well aware of the relative safety of kelp forests and are often spotted hunting along open spaces between the kelp.
How cold does kelp need to grow?
Kelp needs water temperatures to be six and fourteen degrees celsius or forty-three and fifty-seven degrees Fahrenheit. They grow best in cold water, filled with nutrients.

Overview
Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant - it is a heterokont, a completely unrelated group of organisms.
Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. The organi…
Description
In most kelp, the thallus (or body) consists of flat or leaf-like structures known as blades. Blades originate from elongated stem-like structures, the stipes. The holdfast, a root-like structure, anchors the kelp to the substrate of the ocean. Gas-filled bladders (pneumatocysts) form at the base of blades of American species, such as Nereocystis lueteana, (Mert. & Post & Rupr.) to hold the kelp blades close to the surface.
Growth and reproduction
Growth occurs at the base of the meristem, where the blades and stipe meet. Growth may be limited by grazing. Sea urchins, for example, can reduce entire areas to urchin barrens. The kelp life cycle involves a diploid sporophyte and haploid gametophyte stage. The haploid phase begins when the mature organism releases many spores, which then germinate to become male or fem…
Kelp forests
Kelp may develop dense forests with high production, biodiversity and ecological function. Along the Norwegian coast these forests cover 5800 km , and they support large numbers of animals. Numerous sessile animals (sponges, bryozoans and ascidians) are found on kelp stipes and mobile invertebrate fauna are found in high densities on epiphytic algae on the kelp stipes and on kelp holdfasts. More than 100,000 mobile invertebrates per square meter are found on kelp stip…

Conservation
Overfishing nearshore ecosystems leads to the degradation of kelp forests. Herbivores are released from their usual population regulation, leading to over-grazing of kelp and other algae. This can quickly result in barren landscapes where only a small number of species can thrive. Other major factors which threaten kelp include marine pollution and the quality of water, climate changes and certain invasive species.
Prominent species
• Bull kelp, Nereocystis luetkeana, a northwestern American species. Used by coastal indigenous peoples to create fishing nets.
• Giant kelp, Macrocystis pyrifera, the largest seaweed. Found in the Pacific coast of North America and South America.
