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 ...
[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 ).

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.
