What is it about?

Weedy seadragons are an iconic Australian fish. We conducted to first study assessing seadragon habitat use around Sydney, Australia, showing that seadragons strongly associate with kelp habitat (Ecklonia radiata, commonly referred to as leather kelp) and mysid prey. Seadragons select areas where kelp is the dominant habitat and mysid shrimp are present.

Why is it important?

Iconic species such as seadragons can be effectively used as flagship icons for conservation. This was the first study to show these species-habitat relationships in detail. Our findings can be used to inform management strategies for seadragons and to ensure that their conservation status is up to date.


I hope that this article will increase peoples knowledge of seadragons. Unique species, such as the weedy seadragon, may be crucial in helping bring awareness to a range of broader conservation issues, such as habitat loss and climate change. I hope our work raises awareness and encourages engagement with the marine world.
