Phycodurus equesLeafy seadragon
Numerous branched appendages arising from the edges of the body. The leaf-like outline of this species blends in so well with seaweed in its local environment that most divers, as well as predator and prey species, will pass within a metre of the animal without noticing it. This seadragon is common at a few locations in South Australia and is a fully protected species.
Max Size: 35 cm
Sea Temperature Range: 13.3-29.8°C
Habitat Generalization Index: N/A
Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity
IUCN Status: Near Threatened
Occurrence: Infrequent (3.3% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Solitary (1 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
