Algue Balai

Overview

Halopteris scoparia is a brown seaweed known for its distinctive, broom-like appearance. It typically forms dense, rough-textured tufts that thrive in temperate marine environments across the Atlantic Ocean and the Mediterranean Sea.

Appearance

This species is characterized by its compact, bushy growth form, which resembles a small rustic broom or a stiff brush. The seaweed consists of dark brown, highly branched filaments that can reach heights of 5 to 15 cm. Its structure is polymorphous, featuring clear main axes with regular, alternating branches that arise from specific points along the stem.

Distribution & habitat

Halopteris scoparia is widely distributed throughout the Mediterranean, the Black Sea, and the North Atlantic, ranging from Scandinavia to the Cape Verde Islands and parts of the North American Atlantic coast. It is commonly found in shallow, well-lit waters, often inhabiting rocky substrates or sandy areas. In the Mediterranean, it is a notable component of photophilic algal communities in sheltered, high-luminosity environments, while in Atlantic regions, it is frequently observed from the mid-tide zone down into the upper infralittoral zone.
