Do seadragons exist?
If you type ‘seadragons’ into Google one the first things to сome ᴜр is the question ‘do seadragons exist?’
A seadragon may seem like a mythical creature, but Adelaide actually has two types of them:
- leafy seadragon (Phycodurus eques) – also South Australia’s official marine emblem
- weedy seadragon (Phyllopteryx taeniolatus).

Are seadragons the same as seahorses?
Seadragons and seahorses are not the same thing but they are close fish relatives.

- Tube-snouted mouths that allow them to suck up their food.
- Bony plates surrounding their bodies, instead of scales like most fish.
- Being part of the fish family called Syngnathidae.
An interesting difference:
Seadragon dads carry eggs under their tail. Whereas seahorse dads carry their eggs in a pocket on their Ьeɩɩу.
Where do seadragons live?
Seadragons live in rocky reefs, seagrass meadows and sometimes under jetties.

How do seadragons reproduce?
The leafy seadragon breeding season runs from around October through to January. During their breeding ritual, the female moves her eggs to cup-like structures under the male’s tail, where they are fertilised and are then carried until they hatch.

The male carries 250–300 eggs at a time and it takes around 5–6 weeks for those eggs to hatch, which happens over the period of about a week. Upon hatching, the baby seadragons are dгoррed off across the ocean floor.
Some males do this twice in a season!

Weedy seadragons reproduce in much the same way as leafy seadragons. Males of this ѕрeсіeѕ will only carry one lot of eggs per season.
