Durvillaea potatorum

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

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] 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]
