![]() ![]() Snubfins can sometimes be seen swimming with other dolphin species, such as bottlenose and humpback dolphins, socialising or feeding together. To avoid amorous attention, you may see an inversion, where the dolphin turns up a flushed pink belly to avoid mating attempts. They can become very active, splashing at the water’s surface. This species is gregarious and can form large groups of up to 20-30 individuals with lots of close body contact when socialising. After a couple of years, the calves are weaned and become independent. They only have one young at a time, and a calf stays with its mother suckling milk and swimming close by the mother’s tail in “baby position”.

A group of dolphins resting on the water’s surface, lined up like sausages on a barbeque, is referred to using the very Aussie term “snagging”.Ī snubfin mother and calf. Scientists call this behaviour “bottom grubbing”. Snubfins sometimes emerge from a feed covered head to fluke in muddy clay. They perform yoga-like movements, such as head stands with their tail flukes out, while rummaging around the sea floor for fish that are hiding in the mud. They can be very entertaining to watch as they feed in shallow waters. These dolphins are brown in colour, with a low surfacing profile – as such, they are very camouflaged in the shallow, muddy waters that they prefer. They have been observed displaying a specialised tactic of “spit feeding”, where they squirt a jet of water up to two metres high ahead of themselves, and seemingly startle fish back towards their mouths for an easy snack. Snubfin dolphins’ favourite food is fish of varying sizes, from large salmon to small baitfish, and they can often be found feeding in creek mouths on a high tide. The marks are handy to scientists, who use them as natural tags to tell individuals apart and track the dolphins over time through repeated photographs and sightings. The snubfin dolphin has a small circular fin on its back, and they often sport marks on these fins from interactions with other dolphins, sharks that try to eat them, entanglement in fishing gear, and being struck by boats. These dolphins have a distinctive appearance, with a blunt, round head and no beak, which makes them peculiar compared to the more familiar dolphin species. The highest-density population, consisting of about 100 individuals, inhabits Yawuru sea country in Roebuck Bay, Broome, Western Australia. There are currently thought to be less than 10,000 adults of the species. ![]() It was previously thought to be the Irrawaddy dolphin, a close relative that lives in Asian waters. The snubfin dolphin lives in tropical waters of northern Australia and was only recently recognised as a species, in 2005. Snubfin dolphins have a distinctive rounded head and no beak. ![]() Because of this, they can surface and take a breath without showing their dorsal fin – very sneaky! This means scientists must be patient when trying to photograph their dorsal fins to identify individuals and track them over time. Superpower: Snubfin dolphins have vertebrae that make them able to flex their necks, unlike most other dolphins and whales. ![]()
