Note: The species is common in the sublittoral. It is perennial with a variable appearance during the year. It overwinters as coarse and dark brown axes from which new and light brown shots with irregular branches appear during spring. The new shoots are densely set with short, oppositely placed bundles of hairlike and uniseriate short filaments, which are shed later in the season. After the bundles of short filaments are shed, the main axes are set with small thorn-like structures.
