[6] [7] 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. [6] [7] 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. [6]
Species in the genus Durvillaea are also sometimes called "bull kelp", but this is just a shortening of the common name southern bull kelp. Durvillaea is a genus in the order Fucales and, though superficially similar in appearance, is not a true kelp (all of which are in the order Laminariales ).
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 ...

Blades from southern bull kelp (rimurapa in Māori) [1] [2] [3] species such as Durvillaea antarctica and D. poha (named after the pōhā) [4] [5] were used to construct the bags. [1] The kelp blades have a 'honeycomb' structure, [ 6 ] [ 7 ] which allows them to be split open, hollowed out (pōhā hau) and inflated into containers.
