Incidence of shark-inflicted bite injuries on Australian snubfin () and Australian humpback () dolphins in coastal waters off east Queensland, Australia.

The ecology and evolution of prey populations are influenced by predation and predation risk. Our understanding of predator-prey relationships between sharks and dolphins is incomplete due to the difficulties in observing predatory events directly. Shark-inflicted wounds are often seen on dolphin bodies, which can provide an indirect measure of predation pressure.

Humpback Dolphins of Western Australia: A Review of Current Knowledge and Recommendations for Future Management.

Among the many cetacean species that occupy Australian coastal waters, Australian humpback dolphins, Sousa sahulensis, are one of the most vulnerable to extirpation due to human activities. This review summarises the existing knowledge, presently occurring and planned research projects, and current conservation measures for humpback dolphins in Western Australia (WA). Rapid and wide-scale coastal development along the northern WA coastline has occurred despite a lack of baseline data for inshore dolphins and, therefore, without a precautionary approach to their conservation.
