Species

Durvillaea is a genus of brown algae in the monotypic family Durvillaeaceae. It is named after French explorer Jules Dumont d'Urville (1790-1842).[7] There are currently six recognised species within the genus, with the type species D. antarctica.[1] All members of the genus are found in the southern hemisphere, particularly New Zealand, South America, Australia and various subantarctic islands. Many Durvillaea species are referred to as bull kelp, which is a common name for a large kelp.[5][8]

Species

Morphology & Ecology

Durvillaea spp. are characterised by their prolific growth, plastic morphology and ability to withstand high levels of disturbance at rocky, wave-exposed coastal sites.[9]

Use of Durvillaea spp.

D. antarctica has been used in Chile as a food item, predominately by the Mapuche indigenous people who refer to it as collofe.[11] In Australia, D. potatorum is collected as beach wrack from King Island, where it is then dried as chips and sent to Scotland for phycocolloid extraction.[12]
