Specimen from Pichicuy, Chile.
context_page_description: Durvillaea is a genus of brown algae in the monotypic family Durvillaeaceae. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands.
context_section_description: Durvillaea species are characterised by their prolific growth and plastic morphology.
  Two species, D. antarctica and D. poha are buoyant due to a honeycomb-like structure in the fronds of the kelp that holds air. When these species detach from the seabed, this buoyancy allows for plants to drift for substantial distances, permitting long distance dispersal. In contrast, species as D. willana lack such 'honeycomb' tissue and are non-buoyant, preventing the plants from moving long distances.
