# Leafy Seadragon (*Phycodurus eques*)

> The leafy seadragon (Phycodurus eques) is a seahorse relative draped in leaf-like skin flaps that mimic seaweed on southern Australian reefs. Males brood eggs on a tail patch, adults reach about 35 cm, and the species is Near Threatened as habitat loss and collectors pressure local populations.

## Seaweed in motion

Elaborate leaf-like appendages break up the outline among kelp and seagrass. Tiny transparent fins provide slow propulsion; animals drift with surge more than they swim hard.

## Mysid shrimp specialist

Pipe-like snouts suck mysid shrimp and other small crustaceans. They do not chase rapidly; ambush and precise suction rule feeding. Across its range it is tied to seaweed beds and rocky reefs, and field accounts emphasise this species’ distinctive ecology rather than generic habitat labels.

## Southern Australian coasts

Seaweed beds and rocky reefs from Western Australia across South Australia to Victoria. Across its range it is tied to seaweed beds and rocky reefs, and field accounts emphasise this species’ distinctive ecology rather than generic habitat labels.

## Near Threatened icon

Protected in Australia and listed Near Threatened. Storm damage to seagrass, pollution, and past collection for curios harm local groups; diving tourism now mostly photographic.

## Frequently asked questions

### Are leafy seadragons seahorses?

They are close relatives in the family Syngnathidae, but seadragons form distinct genera.

### Do male leafy seadragons get pregnant?

Males carry and aerate eggs on the underside of the tail until hatch — similar parental care to seahorses.

### Why are leafy seadragons Near Threatened?

Limited range, habitat degradation, and historical collecting reduced some populations.

### Can you keep a leafy seadragon as a pet?

Wild collection is illegal; they are protected Australian wildlife needing specialised public-aquarium care.

### Where do leafy seadragons live?

Southern Australian coasts from Western Australia to Victoria. Native range summary: Southern Australian coasts from Western Australia to South Australia and Victoria.
