Leafy Seadragon

Phycodurus eques

Also known as Glauert's Seadragon, Leafy Sea Dragon

Leafy seadragons drift seamlessly through temperate southern Australian shallows, using intricate, leaf-shaped lobes of skin to mimic undulating kelp fronds and evade detection. Propulsion comes entirely from tiny, nearly transparent fins that flutter rapidly while leaving the body virtually motionless to casual observers and predators alike. Males take on sole parental duty, incubating up to 250 bright pink eggs glued to a specialized brood patch beneath their tails until independent young emerge.

What to notice

Support conservation
Never chase, corner, touch, or attempt to handle them, and report any illegal poaching activity to fisheries authorities.
Responsible observation
  • Diving Etiquette: Maintain neutral buoyancy and keep at least a meter of distance to avoid stressing them or damaging sensitive kelp beds.
  • Photography: Refrain from using high-intensity strobes or persistent video lights, which can disorient these slow-moving fish.
