Durvillaea potatorum

Durvillaea potatorum is a large, robust species of southern bull kelp found in Australia. [1]

Contents

Description

The species can be confused with Durvillaea amatheiae , which has an overlapping geographic distribution. [1] [2] D. potatorum has a shorter, wider stipe with more limited lateral blade development, whereas D. amatheiae has a shorter, narrow stipe and typically prolific lateral blade development. [1] [2]

Distribution

Durvillaea potatorum is endemic to southeast Australia. [1] [2]

Uses

Durvillaea potatorum was used extensively for clothing and tools by Aboriginal Tasmanians, with uses including material for shoes and bags to transport freshwater and food. [3] [4] The Aboriginal Peoples of Tasmania continue to collect and use bull kelp for cultural purposes; it is a cultural keystone species. Currently, D. potatorum is collected as beach wrack from King Island, where it is then dried as chips and sent to Scotland for phycocolloid extraction. [5]
