Mesmerising photos<\/a> capturing native Australian dolphins donning sea sponges and other stunning headwear have been shared showing an ultra-rare marine courtship act rarely seen by people.<\/p>\n

The shots, which recently resurfaced online and sparked a wave of fascination, were captured a few years ago in the Dampier Archipelago\u2019s Flying Foam Passage, off Western Australia\u2019s<\/a> rugged Burrup Peninsula, by scientists from the Department of Biodiversity, Conservation and Attractions (DBCA).<\/p>\n

The images show male dolphins<\/a> engaging in an extraordinary and rarely seen courtship ritual \u2014 collecting and presenting sea sponges to potential mates, almost like romantic gifts. In some cases, they even balance the sponges on their heads or snouts.<\/p>\n

For Senior Research Scientist Holly Raudino, from DBCA\u2019s Marine Science Program, the renewed attention has been a welcome reminder of just how special and fragile this little-known species is.<\/p>\n

“There\u2019s renewed interest in the species because they\u2019ve actually been uplisted to vulnerable under the EPBC Act,” Dr Raudino told Yahoo News Australia. “People are concerned about their population status and them being threatened.”<\/p>\n

The dolphins in the photos are Australian humpback dolphins \u2014 a coastal species found only in northern Australian waters, and one of the few known to display such unusual, social behaviour.<\/p>\n

Unique dolphin courtship only ‘seen in a handful of places’<\/p>\n

“It\u2019s quite unique,” Dr Raudino said of the behaviour. “It\u2019s only been seen in a handful of places \u2014 two in the Pilbara, which are Dampier and Exmouth, and also up in the Kimberley. I haven\u2019t even seen it that many times, and I\u2019ve been out there a lot.”<\/p>\n

While other dolphins, like the bottlenose population in Shark Bay, use sea sponges as tools to protect their snouts while foraging, humpback dolphins appear to do it for love. “This has been shown to be just the males using it, so it\u2019s definitely in a sexual context,” she said.<\/p>\n

Incredibly, the behaviour has only been documented a few times worldwide. When Dr Raudino and her team first witnessed it, they were thrilled. “We were very excited,” she said. “There are videos, which we usually turn the sound down on because we\u2019re all squealing and exclaiming.”<\/p>\n

Researchers were actually in the area on a different mission at the time, collecting DNA samples from the dolphins\u2019 blow to study genetics, when they stumbled upon the display. “Then, incidentally, we observed them doing this behaviour,” Dr Raudino said.<\/p>\n

More funding needed to help understand little-known species<\/p>\n

Now, with the species officially listed as vulnerable, she\u2019s calling for more funding to help researchers better understand and protect them. “We\u2019d need to do a dedicated study,” she said. “We\u2019d probably have to survey where the sponges are and look at how that overlaps with dolphin sightings. That would be a great project \u2014 we\u2019d definitely need more funding to do that.”<\/p>\n

Understanding these quirks of behaviour<\/a>, she said, is key to ensuring the species survives. “They\u2019re endemic to Australia and were only fairly recently described \u2014 the taxonomy was only resolved about 10 years ago,” Dr Raudino said. “If we don\u2019t look into it more, we don\u2019t know what we\u2019re losing.”<\/p>\n

Dolphins’ astonishing knack for creativity<\/p>\n

Dolphins are renowned for their problem-solving skills and complex social interactions. They can work together to herd fish, coordinate hunting strategies, and even protect weaker members of their pod from predators. Some dolphins have been observed using sponges as tools to protect their snouts while foraging along the seafloor, a behaviour that\u2019s passed down from mother to calf, showing evidence of culture and learning.<\/p>\n

Their intelligence also extends to communication. Dolphins use a variety of clicks, whistles and body movements to convey messages, and some species even have signature “names” \u2014 unique whistles that identify individual dolphins within a pod.<\/p>\n

They\u2019ve been known to cooperate with humans in certain tasks, respond to trained commands, and display playful curiosity with objects, boats and even other animals, revealing a remarkable capacity for learning, adaptation, and social complexity.<\/p>\n
