Description 1

Reddish macro algae with a hierarchic feather structure, formed by a single axis of up to 9 cm. From the upper section an important density of branches is derived and spread in all directions which in turn also branch off. Individual plants fixed to the substrate by cylindrical stolons of 1.5-2 mm in diameter, irregularly bifurcated. It forms extensive mantles of grey and pink tones in the depths of the sea. It distinguishes itself from Asparagopsis armata by its stolons with harpoon-like hooks and its preference for colder waters.

Biology 1

High fertility, growth and dispersion capacity rates. Sexual and asexual reproduction (fragmentation) with a gametophyte phase (=Asparagopsis) and a tetrasporophyte phase (=Falkenbergia), the last epiphyte. The gametophyte is found in the lower eulittoral zone and, occasionally in mid eulitoral zone. Short life cycles, individual transported algae reach sexual maturity in a short time. In the sexual phase it produces a large quantity of toxic volatile halogen compounds that suggest fungicidal and antimicrobial activity.

Habitat 1

Species native to intertidal zones that are not particularly deep, where it establishes itself on the rocky substrate and/or on other organisms, such as Posidonia Oceanica or species of the Corallina genus. Its range of distribution can be found mostly between the surface and 50 m in depth.
