Ancient aquatic origins of echidnas revealed by Australian scientists
A team of Australian and international scientists believe many of the echidna's unusual traits were developed millions of years ago when its ancestors lived in the water. This is based on the results of a study announced in April. Echidnas and the semi-aquatic platypus are believed to have evolved from a common ancestor called Kryoryctes cadburyi that lived in Australia more than 100 million years ago. Echidnas and platypuses are monotremes, a rare group of mammals that lay eggs instead of live young. Palaeontologist Suzanne Hand said that echidnas had fragile bone walls that made it easier to walk on land. Hand is a palaeontologist at the University of New South Wales. This shows that echidnas came from an ancestor living in water but evolved to live on land. It was far more common for prehistoric mammals to go from land to water, Hand said, pointing towards seals, whales, dolphins and dugongs. Echidnas have hind feet that point backwards. That helped them move lots of soil when burrowing. Hand said that the echidna's ancestor might have first used these feet like rudders to move through fast water. Echidnas also have a 'diving reflex' when they go underwater. This tells their body to conserve oxygen to help them hold their breath for longer. Agence France-Presse

'Stranded' Eddie the echidna thought to have swum from Bribie Island's broken tip
An echidna found washed up on the Caloundra foreshore may have swam more than a kilometre from the isolated northern tip of Bribie Island. Locals and wildlife carers believe the animal may have been swept away overnight during a high tide and say it could be "Eddie", a solitary echidna first spotted several weeks ago on the eroding spit of land. Sunshine Coast resident Dave Cairns discovered the echidna at the base of a rock wall near Golden Beach and said it was alive but appeared to be exhausted. "I think it floated across overnight," he said. "It was about a kilometre from where wildlife's been trapped [on the spit]. "With the tide and swell, it could've easily been swept off." Mr Cairns said in all his years living near the passage he had never seen an echidna in that part of Golden Beach. "Never — not once in 30 years," he said. "It's why I reckon it came from the tip [of Bribie]." The echidna is now receiving veterinary care at Australia Zoo's animal hospital, being treated for exposure to salt water. Licensed wildlife carer Sybelle Foxcroft took the creature in and said the echidna was in a humidicrib receiving oxygen. She has previously taken part in a search of the island's tip to locate any animals that were isolated. Ms Foxcroft said she believed it was the same echidna they had been tracking for several weeks. "Looking at footage, his size and condition, it matches what I'd expect if he'd gone without proper food," she said. Where the echidna was found is a densely populated area with apartment buildings and foreshore infrastructure, with little suitable ground for echidnas to burrow or shelter. Dr Kate Dutton-Regester, a wildlife conservationist and lecturer at the University of Queensland, said echidnas were capable swimmers, though it was not often seen. While typically found around freshwater sources, she said echidnas could plausibly travel some distance in salt water, particularly if assisted by currents. Dr Dutton-Regester said the symptoms described were consistent with salt water exposure. She said the echidna could have been swept off the island or may have entered the water voluntarily, but she could not confirm whether it came from the tip of Bribie Island. "We're at the beginning of echidna breeding season," Dr Dutton-Regester said. "If it's a male they often roam more widely in search of a mate." Dr Javier Leon, a coastal erosion expert from the University of the Sunshine Coast, said recent conditions may have already displaced some animals. "We have had a large swell from the east the last two days that might have contributed to further erosion and, potentially, the wash-over of wildlife," he said. He said the area had already been severely damaged following ex-Tropical Cyclone Alfred in February and warned it would become uninhabitable for animals. Jen Kettleton-Butler from the Pumicestone Passage Catchment Management Body (PPCMB) also travelled to the tip with a wildlife carer at sunset last week in an effort to locate Eddie, but they were unable to find the animal. Animals including goannas, lizards, snakes and small marsupials have recently been observed on the isolated section. Ms Kettleton-Butler said the spit, cut off by two tidal breakthroughs, now measured about 30-40 metres wide and 300-400 metres long and appeared to be shrinking with every high tide. When first contacted the Department of Environment said it had not seen any evidence of worsening impacts on wildlife at the northern tip of Bribie Island that would justify intervention. The statement said the animals in the area were considered to be adapted to rapidly changing coastal conditions. The department has been approached for further comment following the discovery of the echidna at Golden Beach. Deputy Premier Jarrod Bleijie previously said he would request expert coastal engineers to urgently investigate the erosion and assess potential risks to wildlife.

Echidna mothers change their pouch microbiome to protect tiny ‘pink jelly bean' puggles, new research finds
When echidna mothers nurse their young, known as puggles, the microbiome of their pouch changes to protect their babies in their first weeks of life, new research has found. These first few weeks are critical for puggles. At this early developmental stage, they are tiny – roughly the size of a 5-cent coin – and vulnerable. 'They can't see and they don't have a functional immune system,' said Isabella Wilson, lead author of the study published in FEMS Microbiology Ecology. Echidnas lay their eggs into a temporary pouch, which they create by contracting their abdominal muscles. After about 10 days, puggles hatch from their eggs looking like, in Wilson's words, 'little pink jelly beans'. During lactation, probiotic bacteria in the echidna's pouch increases, which the University of Adelaide researchers suggested offers protection to puggles and their developing immune systems. The reproductive biology of the echidna is unique in many respects, Wilson said. Monotremes – echidnas and platypus – share a lot of 'weird features', she said. As well as laying eggs, they lack nipples. So instead of suckling, puggles rub their beaks against a part of the pseudo-pouch called the milk patch, causing milk to come out of the mother's skin. Sign up for Guardian Australia's breaking news email This milk, which is sometimes pink, has barely any lactose compared to that of most other animals. 'The young hang out there [in the pseudo-pouch] for a few months, drink up a lot of milk,' Wilson said. 'Then, when they start to grow spines, they get turfed out of the pouch into the nursery burrow – where they continue to feed off mum for about 200 days.' An echidna's pouch is only temporary – it is there while a puggle is inside. Healesville Sanctuary echidna keeper Craig McQueen, who was not involved in the research, agreed puggles generally stayed there for six to seven weeks, until their spines became 'too prickly' for mum. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion He said echidnas were curious animals that invested a lot of time into raising their young. When they hatch out of their grape-sized egg, puggles are furless, blind and 'basically looked like they shouldn't have been born yet', he said – which is why they need the 'extra developmental time' in the pouch. The paper explains that the reproductive microbiome, 'which includes vaginal, milk, and mammary microbiota, is increasingly being recognised for its contributions to infant health'. And in monotremes and marsupials, this extends to the pouch. Researchers analysed bacteria present on swabs from both captive animals at Taronga Zoo and wild echidnas on Kangaroo Island. They found that the pouch's microbiome underwent significant changes during lactation, with an increase in lactic acid bacteria typically thought of as probiotic. They found no major difference between the microbiomes of the zoo-managed and wild animals. Wilson said this suggested that milk, rather than any external factors, is the primary element shaping the pouch environment.

‘It's pretty scary': Sunshine Coast residents fear storm surges as Bribie Island buffer erodes away
Jen Kettleton-Butler is on 'a postage stamp of island' trying to rescue an echidna she calls Eddie. Wind roars in her microphone and the camera she holds pans from a public toilet that is disappearing beneath waves to a thin strip of coastal forest that, too, is being reclaimed by the ocean. 'This is weeks, if months, you know, at the most, before this is gone,' she tells her social media followers. It is the first Saturday in May and Kettleton-Butler is standing on an uninhabited strip of Bribie Island a few dozen metres wide that has been dissected to the north and south by two successive breakthroughs – one by the wind and waves associated with ex-tropical Cyclone Seth in 2022 and the other by Alfred in March. With the tide fast coming in, Kettleton-Butler calls off the search for Eddie, hoping he can be found at a later date. She hopes too that the 'weather settles down a little bit' over winter and 'stops pounding' the island while 'we actually get our ducks in a row and get some sort of coastal engineering solution in place to put back our barrier island'. Behind the disappearing forest is a narrow passage of calm water upon whose far shore sits the houses of Caloundra, framed by the distinctive volcanic peaks of the Glass House Mountains. Kettleton-Butler points to the settlement on the mainland. Sign up for Guardian Australia's breaking news email 'We need to put back our barrier island,' she says. 'We need to re-establish our bar back at its traditional position. Because those are the conditions and the assumptions around which we built our home on the edge of the water there'. Just what does happen to this disappearing strip of northern Bribie Island is now subject to review by the Liberal National state government. And the LNP Caloundra MP, Kendall Morton, says Kettleton-Butler is far from the only one of her constituents clamouring for action. Morton says she knocked 10,000 doors on the Sunshine Coast in her bid to win the seat and take government from Labor. This was in the top three issues, she says. 'For a long time – like decades – we've watched Bribie Island slowly erode away, particularly on the northern tip,' she says. 'It's pretty scary.' The real 'risk and danger' posed, she says, is not to the residents of Bribie, who live on the wider, southern end of the island. Instead it is those on the foreshore of the mainland. In the absence of the Bribie buffer and without the dune system on the surf coast, they would suddenly be exposed to storm surge and inundation. skip past newsletter promotion Sign up to Breaking News Australia Get the most important news as it breaks Privacy Notice: Newsletters may contain info about charities, online ads, and content funded by outside parties.

But the new MP says the review will consider the impacts of human intervention, from dredging and wake from the offshore shipping channel to widespread coastal development. 'We've gone from a beachside town 40 years ago to a population of 100,000-plus people,' she says. Bribie Island resident, retired engineer and environmental volunteer John Oxenford agrees human intervention has fuelled the erosion – but he points to the 2007 opening of the beach to four-wheel drives as 'opening a real Pandora's box'. The pressure of tens of thousands of vehicles and associated foot traffic since had prevented the natural regrowth of dunes during the winter period, and further exposed them to erosion during the summer months, he says. 'Year over year over year, we've seen rapidly escalating volume of traffic on the ocean beach,' he says. 'The end result of that is erosion.' As well as what is causing the erosion, the government review will look at what can be done – with Morton pointing to the sand groin and sand pump system used on the Gold Coast. In the meantime, however, the state environment department will not be sending out any rescue parties for Eddie the echidna. 'The department is not aware of any evidence of increased impacts on the survival or welfare of wildlife inhabiting the northern tip of Bribie Island that would warrant any form of intervention,' a spokesperson says. 'These animal populations are adapted to a highly dynamic coastal environment with rapid and unpredictable changes.'
