Asparagopsis armata

description Asparagopsis armata Overview

Asparagopsis armata is a red alga (Rhodophyta) native to Australia and the Southern Hemisphere that became established as an invasive species along European Atlantic coastlines by the early 20th century and is now widely naturalized there. It is commonly known as 'harpoon weed' due to the barbed, hook-like branchlets on its feathery thallus that cling to vessels and marine equipment, facilitating vegetative dispersal. The species has a complex life cycle with a conspicuous feathery gametophyte stage and a separate filamentous tetrasporophyte stage historically described under the name Falkenbergia rufolanosa.
