Peacock tail - Padona Pavonica

The Peacock or Peacock tail,  (Thivy 1960) is a brown seaweed from the Dictyotaceae family. Pavonia coda di pavone Padina pavonica Dictyotaceae Padina pavonica Dictyotaceae

The name Peacock tail derives from the characteristic shape of the alga’s Tallo, which opens to fan from a stalk anchored to the substrate by means of rizoidi. The texture is leathery.

The color is light brown, tending to white, with more or less dark bands due to the presence of calcium carbonate that is fixed on the surface of the seaweed. Up to even 20 centimeters in diameter.

It grows from the end of the winter period until spring advanced; The reproduction takes place in summer.


Common in the Mediterranean Sea, Black Sea and the eastern Atlantic Ocean from the coasts of Morocco to the English Channel, and the Northwest Atlantic.

It often lives in numerous groupings, from a few centimeters up to about 20 m of depth, on well-lit hard seabed. It tolerates well even wide variations of temperature.

From the Peacockn Padia is extracted an active principle called Padia HPS3 used in cosmetics to moisturize the skin. The HPS3 goes to stimulate in the cells the production of glucosaminoglucani that have the capacity to retain the water and thus to fight the skin ageing.

  Pavonia coda di pavone Padina pavonica Dictyotaceae

Description Padina pavonica is a distinctive small brown alga growing to a diameter of up to 10 cm (4 in). Young fronds are thin, leafy and flat, with entire margins. Older fronds are thicker, concave, fan-shaped or funnel-shaped, with lobed margins. The outer (under) surface has concentric rows of small, fine hairs and is banded with zones of olive green, pale and dark brown, while the inner (upper) surface is covered with a thin layer of slime. Both sides are thinly calcified and the margins tend to curl inwards. The blades are attached by a holdfast which may be matted.

Distribution and habitat This seaweed has a wide distribution in the northeastern Atlantic Ocean, the Mediterranean Sea, the southern Atlantic Ocean, the Indian Ocean and the Pacific Ocean. The British Isles is its most northerly limit in the Atlantic Ocean, and it occurs on the south coast of Ireland, in Pembrokeshire and on the south coast of England. It grows in pools in the littoral zone and in the shallow infralittoral zone. It typically grows where there are sandy, clayey or silty sediments in pools beneath receding mudstone and sandstone cliffs. Other habitats include mangrove roots, rocks, pieces of shell, seagrass meadows and coral reefs on flats in the lower intertidal zone.
