Cnidarian

Identification & Biology

  • IdentificationA branching sea fan with slender, flexible branches arranged in a bushy, three-dimensional pattern (not flat like many gorgonians). Orange to reddish-orange, with tiny white polyps dotted along the branches.
  • SizeColony height up to 50 cm. Branches are thin and flexible.
  • Social HabitColonial. Found on rocky surfaces in areas with moderate current. Polyps extend to feed, primarily at night.
  • HabitatRocky reefs, walls, and overhangs. Prefers areas with moderate water movement.
  • Depth10 to 100 m. Most common between 15 and 50 m.
  • Feeds OnPlankton and suspended organic particles captured by the polyps.
  • DistributionEastern Atlantic from Portugal to West Africa, and throughout the Mediterranean Sea. Present in Maltese waters.
  • DescriptionLeptogorgia sarmentosa is a modestly sized gorgonian that adds colour to Mediterranean rocky reefs. Unlike the larger sea fans that grow in a flat plane, this species branches in all directions, forming bushy colonies. The orange colour and white polyps make it easy to identify. It is relatively common in Malta on walls and overhangs in the 15 to 40 m range.

Detail

Preferred Environment

Reef & Open habitats, typically at depths of 0-40m. Most commonly encountered by divers at the shallower end of its range.

Encounter Tips

Best approached slowly and calmly. Avoid casting shadows directly over the animal. Neutral buoyancy and patience increase encounter success significantly.

Biology

Behaviour & Diet

Feeding Strategy

Polyps extend to capture zooplankton and fine particulate organic matter from passing currents. Colonies position themselves across the current to maximise the filtration surface area.

Suspension feeder

Reproduction

A gonochoric species, with colonies being either male or female. Eggs are fertilised internally and brooded as planula larvae before summer release.

Internal brooding

Behaviour & Defence

Contains anti-fouling and toxic secondary metabolites in its tissues that deter predation and prevent overgrowth by algae and encrusting organisms. The rigid gorgonin skeleton resists breakage.
