Holdfasts of D. antarctica are often inhabited by a diverse array of epifaunal invertebrates, many of which burrow into and graze on the kelp. [25] In New Zealand, epifaunal species include the crustaceans Parawaldeckia kidderi, P. karaka [25] and Limnoria stephenseni, and the molluscs Cantharidus roseus, Onchidella marginata, [26] Onithochiton ...
Kelp forests are some of the most productive ecosystems in the world - they are home to a great diversity of species. Many groups, like those at the Seattle Aquarium, are studying the health, habitat, and population trends in order to understand why certain kelp (like bull kelp) thrives in some areas and not others.
A pōhā covered with tōtara bark and inserted into a flax basket.. Pōhā are traditional bags used by the Māori people of New Zealand made from southern bull kelp, which are used to carry and store food and fresh water, to propagate live shellfish, and to make clothing and equipment for sports.
[8] [9] Specimens of D. antarctica have been found to float for up to 210 days, during which time high wind speeds transport kelp rafts up to 10,000 km. [8] [9] Environmental factors such as temperature, solar radiation and surface winds (all of which vary with latitude) affect buoyancy of southern bull kelp rafts and their rate of travel. [8]
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]
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 .
The species is endemic to New Zealand, and is predominantly found along southern coasts of the South Island and on Stewart Island, as well as on the subantarctic Snares and Auckland Islands. [ 1 ] [ 3 ] [ 4 ] [ 6 ] Based on genetic data, the species appears to have undergone a recent range expansion into the North Island, as it can be found at ...
