Rhynchobatus australiae

Rhynchobatus australiae, commonly known as the white-spotted guitarfish or white-spotted wedgefish, is a large cartilaginous fish belonging to the family Rhinidae. This distinctive ray species is characterized by its flattened, guitar-shaped body and can reach lengths of up to 3 meters. The species is endemic to the Indo-Pacific region, with populations distributed along the coasts of northern Australia, Papua New Guinea, and Indonesia.

White-spotted guitarfish inhabit shallow coastal waters, typically found on sandy and muddy bottoms in depths ranging from nearshore areas to approximately 60 meters. As a demersal species, it feeds primarily on small fish, crustaceans, and mollusks. The species faces severe population declines due to intensive fishing pressure, both as target catch and bycatch in commercial fisheries.

Its large size, slow growth rate, and late sexual maturity make it particularly vulnerable to overexploitation. Habitat degradation from coastal development and pollution further compounds these threats. The meat, fins, and other body parts are valued in international markets, driving continued fishing pressure.

Conservation efforts include implementation of fishing restrictions in some jurisdictions, habitat protection measures, and international trade regulations under CITES Appendix II listing. However, enforcement remains challenging across its range, and coordinated regional management strategies are essential for the species' recovery.

This species inhabits shallow coastal waters of the Indo-Pacific, typically found on sandy and muddy substrates from nearshore areas to depths of approximately 60 meters. It prefers tropical and subtropical marine environments along continental shelves and around islands.
