Leafy Seadragon

Phycodurus eques

Dallas World Aquarium, Dallas, Texas, USA

Least Concern

To date there have been few dedicated surveys and no population estimates for Phycodurus eques. Just one estimate of density exists for this species, from a single location at one time. Connolly et al. (2002a) estimated the density of Leafy Seadragons around West Island, in Encounter Bay, to be 57 fish per ha (small juveniles (less than 100 mm) were not included in the study). Further research is needed in order to determine population size across the species' range, and monitoring should be undertaken to determine trends in abundance. The species is likely declining as a result of ongoing coastal ... Read More

Phycodurus eques is threatened by coastal habitat loss and degradation and by being caught as bycatch in fisheries. Leafy Seadragons are associated with seagrass beds and reefs supporting macroalgae (Connolly et al. 2002b). These habitats have been adversely affected by human activities and loss in quality and quantity has been documented and is ongoing (Baker 2003, Marzinelli et al. 2015). The loss of habitat is most severe near major urban centres (e.g., Perth, Adelaide, Melbourne), where discharge of storm water and treated sewage leads to eutrophication and increased sedimentation. Losses of seagrass have been particularly severe along the metropolitan coasts ... Read More
