The Australian snubfin dolphin (Orcaella heinsohni) was only described by science in 2005 but already many populations are believed to be in decline as a result of expanding aquaculture and fisheries activity, boat strike and foreshore development. Comprehensive research and precautionary management are key to the snubfin’s long-term survival.

The bottlenose dolphin (Tursipos sp.) is the world’s most recognisable small cetacean because of its wide distribution.  Even so, many local populations are threatened, directly and indirectly, by human activity.

The Indo-Pacific humpback dolphin (Sousa chinensis) inhabits inshore waters including river-mouths.  Its rounded forehead, long, narrow beak and triangular dorsal fin enable it to be distinguished from other inshore species.
