DESCRIPTION OF TAXONOMIC GROUP FOR EXPERT ASSESSMENT
Following taxonomic standards, 20 dolphin species in the Family Delphinidae and one species in the Family Phocoenidae are known to occur in Australian waters (Table 1). A number of these species (e.g. common dolphins, Delphinus delphis) are distributed nationally, others are restricted to particular latitudes (e.g. dusky dolphin, Lagenorhychus obscurus) and others consist of populations that are highly restricted to embayments and tributaries within particular regions (e.g. the endemic Australian snubfin dolphin, Orcaella heinsohni).
Since the 2016 State of the Environment (SoE) report further insights into the spatial distribution of Australian snubfin dolphin (Blue Planet Marine 2019, Bouchet et al. 2021), Australian humpback dolphins (Sousa sahulensis; Parra and Cagnazzi 2015, Hanf et al. 2016, Hunt et al. 2017; Raudino et al. 2018a, Raudino et al. 2018b, Blue Planet Marine 2019, Burns et al. 2019, Hunt et al. 2020), Indo-Pacific bottlenose dolphins (Tursiops aduncus, Raudino et al. 2018a, Blue Planet Marine 2019, Burns et al. 2019, Haughey et al. 2020), common dolphins (Delphinus delphis, Mason et al. 2016) and orca (Orcinus orca, Jones et al. 2019, Salgado-Kent et al. 2020) have been established.
