Marine Plant

Identification & Biology

  • IdentificationA small, fan-shaped brown alga with distinctive concentric bands of lighter and darker brown running across the blade, resembling a peacock's tail feather. The blade is thin, flat, and slightly curled at the edges. Often covered in a fine white calcareous deposit.
  • SizeBlade height up to 15 cm. Width up to 8 cm.
  • Social HabitFound in groups on rocky surfaces in shallow water. The banded pattern is caused by alternating zones of reproductive and vegetative growth.
  • HabitatShallow rocky reefs, tide pools, and any hard surface in well-lit water.
  • Depth0 to 20 m. Most common between 1 and 10 m.
  • Feeds OnPhotosynthetic. Produces food from sunlight through photosynthesis.
  • DistributionWorldwide in warm and temperate seas. Common throughout the Mediterranean and on all Maltese rocky shores.
  • DescriptionPadina pavonica is one of the most distinctive and commonly encountered algae in Malta. Its fan-shaped blade with concentric banding is easy to recognise in tide pools and on shallow reefs. The white calcareous coating on the surface makes it one of the few algae that contribute to calcium carbonate production. It is an important primary producer and food source for herbivorous fish and sea urchins.

Biology

Behaviour & Diet

Feeding Strategy

Produces energy through photosynthesis using sunlight penetrating the water column. Forms dense meadows that are critical nursery habitat and oxygen producers for the Mediterranean ecosystem.

Photosynthetic

Reproduction

Reproduces vegetatively and sexually. Vegetative growth is the dominant strategy; sexual reproduction is seasonal and infrequent.

Seasonal spawning

Behaviour & Defence

Posidonia and other Mediterranean seagrasses form protected meadows under EU Habitats Directive. These habitats are sensitive to anchor damage, trawling, and water quality. Recreational divers should avoid contact with the meadow.
