Description 1

Large, perennial, dark green algae, with erect fronds some 15-20 cm high, with abundant, cylindrical branches distributed in a dichotomous or fastigiate way. Its surface is hairy. They attach to the substrate by means of a wide, spongy basal disk. The cylindrical branches have a diameter of 0.3-1 cm. To touch, it is a soft, spongy algae.

Biology 1

Although it sexually reproduces, it has vegetative and parthenogenetic propagation. Its reproductive period runs from summer to winter, with its peak being in the autumn. Reproduction is favoured in years with warmer climates.

Habitat 1

Rocky substrates, ponds, inter-tidal sand and mud, being able to reach up to 20 m in the sub-littoral zone. It grows easily in environments with full or partial wave exposure, this shows the algae's great ability to adapt and its power to expand due to the fact that the wave encourages its fragmentation and its vegetative dispersion.
