Info
Gymnura australis, the Australian butterfly ray, is a demersal species that lives in nearshore, tidal environments and estuaries.
The ray prefers open, low-structure waters with sandy, muddy, or silty substrates.
This species is sexually dimorphic, with females reaching a larger size than males; females reach a disc width of at least 94 cm, while males reach 57.5 cm.
Estimates suggest that the species has an annual reproductive cycle, producing a litter of 1-6 young every 12 months, with the small rays estimated to be 22-25 cm at birth.
The menu includes mainly bony fish.
Synonym: Pteroplatea australis Ramsay & Ogilby, 1886
