snubfins on the Great Barrier Reef found levels of polychlorinated biphenyls (PCBs) far exceeding the thresholds for small cetaceans, over which reproductive anomalies and immunosuppression can occur. Periodic floods present a temporary threat to snubfin dolphins in that they result in an increase in freshwater discharge, heavy metals, nutrients, sediment and pesticides in coastal areas. Increases in floods, cyclone severity, storm surges and sea surface temperatures due to climate change will likely also affect the habitat and future food supply of snubfin dolphins. As a result of the cumulative effects of drowning as bycatch and habitat loss and degradation, the Australian snubfin dolphin population is believed to be decreasing and is likely to meet the criteria for IUCN's "endangered" status in the near future.

the white belly. The new species has a rounded forehead, very unlike other dolphin species in Australia, and the very small, "snubby" dorsal fin distinguishes it from other dolphins in its range. The lack of a groove on each side of the back and the presence of a neck crease further distinguishes this species from its relative. Tail flukes also have an identifiable jagged trailing edge that can help distinguish it from other species of delphinids.

near-shore areas and near the mouths of rivers, where these dolphins are more likely to be found. Although it is not known how many dolphins die in this manner, it is considered to be the greatest threat to populations in Papua New Guinea. Anti-shark nets and drumlines put in place for Queensland's shark control program are also a significant threat to snubfins, with about 1.8 snubfin dolphins killed every year between 1997 and 2011.

individuals) have also been observed. Populations are usually smaller than 150 individuals. Some instances of long-term sociability have been observed among individuals off the coast of Queensland, Australia. Grouping associations seem to be strongest among male individuals implying some potential correlation to reproductive strategy. Additionally, there was an observation of snubfin dolphins displaying mating courtship between

females can reach lengths of 230 cm (91 in) and males can reach 270 cm (110 in). Australian snubfin dolphins are subtly tricoloured: brownish on the top, lighter brown along the sides, and a white belly; the Irrawaddy dolphin, on the other hand, is uniformly slate grey except for

Pollution is another threat to snubfin dolphins, as the water discharge from rivers in the dolphins' Australian range are contaminated by industrial and agricultural runoff. The snubfin dolphins' strong site fidelity means they are likely exposed to pollutants on a daily basis. Indeed, one study of

In a study of Australian snubfin dolphins consisting of 18 individuals, it was determined the approximate life span is around 30 years. However, since sightings are so rare, a lot remains unknown about many about this species. Gestation is estimated to be around 11 months based on rates of similar

As small populations are more vulnerable to extinction due to the small numbers and low genetic diversity, the snubfin dolphin is at significant risk in their human populated habitat. The insufficient data on the species poses additional threat as their general ecology is not fully understood.

The coastal zones along the Australian snubfin dolphin's range have been highly modified for mining and agricultural purposes as well as ports, aquaculture and residential development. Land reclamation, vessel traffic and construction results in the degradation of the snubfin's natural habitat

Although some hunting by indigenous people occurs (as evidenced by the 1948 specimen), this is likely to be insignificant compared to other threats such as drowning in sharknets and fishing gear. Snubfins are particularly at risk from incidental capture in gillnets, which are often placed in

Much remains unknown about the ecology and behaviours of the Australian snubfin dolphin. Australian snubfin dolphins have a varied diet, eating a range of fish, shrimp, and cephalopods (squid, cuttlefish and octopus). They are found in small groups of about 2–6, but larger groups (up to 14
