A century after its discovery, scientists capture first confirmed footage of a colossal squid in the deep

<div class="theconversation-article-body">The colossal squid was first described in 1925 based on specimens from the stomach of a commercially hunted sperm whale. A century later, an international voyage captured the first confirmed video of this species in its natural habitat – a 30-centimetre juvenile, at a depth of 600 metres near the South Sandwich Islands.</p> <p>Colossal squid can grow up to seven metres and weigh as much as 500 kilograms, making them the heaviest invertebrate on the planet. But little is known about their life cycle.</p> <figure><iframe src="https://www.youtube.com/embed/lzPoG9H8Hlo?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption><span class="caption">The first sighting of a juvenile colossal squid in its natural environment. Credit: Schmidt Ocean Institute.</span></figcaption></figure> <p>The footage of a young colossal squid in the water column was a serendipitous sighting, as many deep-sea squid observations are.</p> <p>It was seen during the live “divestream” feed of a remotely operated vehicle during the <a href="https://2022annualreport.schmidtocean.org/">Schmidt Ocean Institute</a> and <a href="https://oceancensus.org/">Ocean Census</a> partner expedition searching for new deep-sea species and habitats in the far south Atlantic, mostly focusing on the seafloor.</p> <p>Those tuned into the stream had the remarkable experience of seeing a live colossal squid in its deep-sea home, although its identity was not confirmed until the high-definition footage could be reviewed later.</p> <p>Predators such as whales and seabirds are still one of our best sources of information about the colossal squid (<em>Mesonychoteuthis hamiltoni</em>) because they are much better at finding it than we are.</p> <p>This partially explains why we have only just filmed this species in its natural habitat. Not only do these animals live in an enormous, dark and three-dimensional environment, they are also probably actively avoiding us.</p> <p>Most of our deep-sea exploration equipment is large, noisy and uses bright lights if we are trying to film animals. But the colossal squid can detect and avoid diving sperm whales, which probably produce a strong light signal as they swim down and disturb bioluminescent animals.</p> <p>The squid best able to avoid such predators have been passing on their genes for millions of years. This leaves us with a current population of visually acute, likely light-avoiding animals, well capable of detecting a light signal from many metres away.</p> <h2>Delicate beauty of deep-sea animals</h2> <p>The colossal squid is part of the “glass” squid family (Cranchiidae). Three known glass squid species are found in the Antarctic ocean, but it can be difficult to distinguish them on camera.</p> <p>Researchers from the organisation Kolossal, aiming to film the colossal squid, observed a similarly sized glass squid during their fourth Antarctic mission in 2023. But since the characteristic features needed to identify a colossal squid – hooks on the ends of the two long tentacles and in the middle of each of the eight shorter arms – weren’t clearly visible, its exact identity remains unconfirmed.</p> <p>In the Schmidt Ocean Institute footage, the mid-arm hooks are visible. And for this young individual, the resemblance to other glass squids is also clear. With age and size, colossal squid likely lose their transparent appearance and become much more of an anomaly within the family.</p> <p>While many will be amused by the idea of a “small colossal” squid, this footage showcases a beauty shared by many deep-sea animals, in contrast to the monster hype and “stuff of nightmares” click-bait titles we see all too often.</p> <p>This colossal squid looks like a delicate glass sculpture, with fins of such fine musculature they are barely visible. It has shining iridescent eyes and graceful arms fanned out from the head.</p> <p>At full size, the colossal squid may be a formidable predator, with its stout arms and array of sharp hooks, able to tackle two-metre-long toothfish. But in our first confirmed view of it at home in the deep sea, we can marvel at the elegance of this animal, thriving in an environment where humans require so much technology even to visit remotely.</p> <h2>Stranger than science fiction</h2> <p>Until recently, few people were able to take part in deep-sea exploration. But now, anyone with an internet connection can be “in the room” while we explore these habitats and observe animals for the first time.</p> <p>It’s hard to overstate the importance of the deep sea. It holds hundreds of thousands of undiscovered species, it is probably where life on Earth started, and it makes up 95% of the available living space on our planet.</p> <p>It has animals more splendid and strange than our most creative science fiction imaginings. This includes squids that start life looking like small light bulbs and then grow into true giants; colonies of individuals living together with each contributing to the group’s success; animals where males (often parasitic) are orders of magnitude smaller than females.</p> <p>This first confirmed sighting of a colossal squid inspires and reminds us how much we have left to learn.</p> <hr /> <p><em>The expedition that captured the footage of the colossal squid was a collaboration between the Schmidt Ocean Institute, the Nippon Foundation-NEKTON Ocean Census, and GoSouth (a joint project between the University of Plymouth, GEOMAR Helmholtz Centre for Ocean Research and the British Antarctic Survey).</em><!-- Below is The Conversation's page counter tag.

Incredible breakthrough after scientists make dire wolves "de-extinct"

<p>The legendary dire wolf – an iconic creature that vanished around 13,000 years ago and gained fame through HBO’s <em>Game of Thrones – </em>has made an extraordinary return. This resurgence is the result of a cutting-edge genetic project spearheaded by Colossal Biosciences, marking the first-ever successful "de-extinction" of a species.</p> <p>In a groundbreaking announcement recently, Colossal revealed the birth of three healthy dire wolf pups – Romulus, Remus, and Khaleesi – who were created by combining DNA from ancient dire wolf fossils and the genes of their closest living relative, the grey wolf. The news marks a milestone in both genetic engineering and conservation science, offering a glimpse into the future of species revival.</p> <p>The pups' arrival was made possible by the expertise of Colossal’s team, which used DNA from a 13,000-year-old tooth and a 72,000-year-old skull. Ben Lamm, CEO of Colossal, expressed his excitement over the breakthrough, saying, “It was once said, ‘any sufficiently advanced technology is indistinguishable from magic’. Today, our team gets to unveil some of the magic they are working on and its broader impact on conservation.”</p> <p>The dire wolf pups were created using somatic cell nuclear transfer, a cloning technique that involved inserting cell nuclei from the ancient DNA into donor egg cells. These embryos were then implanted into a surrogate dog mother, who gave birth in January.</p> <p>The pups are now thriving in a secure 800-hectare ecological preserve, where they receive round-the-clock care from a dedicated team of 10 staff members.</p> <p>The dire wolf, once a dominant predator across North America, were fierce hunters that roamed alongside Ice Age megafauna such as mastodons and sabre-toothed tigers. They preyed on large mammals like horses, bison and potentially mammoths, but after these species went extinct, the dire wolf's reign also came to an end. According to palaeontologist Julie Meachen, with the loss of their prey, the dire wolf was gradually replaced by the grey wolf, which filled the ecological void.</p> <p>Dire wolves were notably larger and more muscular than their modern grey relatives, with jaws and shoulders built for powerful hunts. Their revival has captivated both science enthusiasts and pop culture fans alike.</p> <p>Lamm and George Church, a Harvard biologist, co-founded Colossal Biosciences with the ambitious goal of bringing back extinct species. The company is also working toward reviving the woolly mammoth and the Tasmanian tiger, and has already successfully engineered a woolly mouse, known for its curly fur reminiscent of the woolly mammoth's iconic coat.</p> <p>Dr Christopher Mason, a scientific adviser for Colossal, hailed the de-extinction of the dire wolf as a transformative leap in genetic engineering. "This is an extraordinary technological leap for both science and conservation," he stated. "It’s a wonderful example of the power of biotechnology to protect species, both extant and extinct."</p> <p><em>Images: Colossal Biosciences</em></p>

"Colossal prick" slammed over outrageous Bunnings parking

<p>A motorist in Perth has been slammed for their "extra selfish" parking act in the carpark of a Bunning's Warehouse. </p> <p>A frustrated fellow shopper captured the parking faux pas and posted the image of the car to Reddit, which shows a ute with an attached trailer parking over four spaces, including one reserved for people with disabilities.</p> <p>"There was no disabled badge and of course there is plenty of trailer parking available at Bunnings," the user wrote, adding that there were suitable bays available closer to the store's entrance.</p> <p>Fellow motorists and shoppers were shocked and appalled by the selfish act, with one Reddit user urging the author of the post to send the photo to both Bunnings and the local council, citing a $500 fine as a deterrent for the future.</p> <p>"Blocking the disabled bay gets extra selfish points," a user commented, while someone else vented, "Not content with being a colossal prick and taking up four spots, decides to go world-class and make one of those spots a disabled parking bay. Some f**king people."</p> <p>The post was flooded by outrage at the audacious parking, with users overwhelmingly agreeing that parking in spaces designated for disabled drivers is inexcusable.</p> <p>After being alerted to the post, Bunnings Regional Operations Manager Hayley Coulson expressed disappointment on behalf of the retailer. "We were disappointed to learn a customer recently used a disability parking bay for their trailer outside our Innaloo store, which our team was unaware of at the time."</p> <p>"These parking bays are incredibly important for the community and we remind our customers that they're only reserved for people with a disability or mobility restrictions."</p> <p>She added, "We're really focused on ensuring disability parking bays are always available for their intended use, and we do our best to communicate regularly with our stores to remind them that these bays are not to be compromised for any reason, at any time."</p> <p><em>Image credits: Reddit</em></p>
