Description 1

Macro algae with leaf-shaped straight fronds (6-8 mm of diameter) which arise from crawling stolons. Flat fronds in the sides, small side branches narrow in the base, where they are fixed to the rachis of each frond. The normal size of the small branches is 1 cm, and the density 4-7 per centimetre of the rachis. The size of the fronds and their small branches depend on light intensity (if deeper and less light, the frond is bigger), being able to exceed 2 m. Similar to C. racemosa, but longer and with a greater growth rate.

Biology 1

Both sexual and asexual reproduction (fragmentation). Sexual reproduction is little known and its expansion is mainly due to the spreading of fragments in coastal marine areas with low depth (up to 30 m), where there are the appropriate conditions for its settlement and proliferation. It grows from June to September from the stolons.

Habitat 1

Littoral sedimentary areas and sublittoral zones on rocks and other substrates: sand bottoms, mud, closed bays, phanerogams and artificial substrate grasslands (piers, metal buoys, rubber blocks, plastic pipes, etc.). Depth range between 1-35 m, up to 100 m. Optimal temperature between 20-30oC It may live in extreme conditions (out of water and with humidity) for 10 days. It can tolerate eutrophic conditions and standing waters. It can tolerate severe limitation of nutrients.
