Much remains unknown about the ecology and behaviors 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 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 Australian humpback dolphins.
