An orcas diet consists of Chinook salmon and can eat up to two dozen fish a day - so why is it that the killer whales like to bully porpoises despite them not being part of their diet? That's the question which has left scientists scratching their heads, as the study published in Marine Mammal Science seeks to add further understanding to this subject. Around 78 cases of orcas targeting porpoises were noted by researchers from the UK, USA and Canada. It was said to be happening in the Salish Sea (located in the Canadian province of British Columbia and the U.S. state of Washington). Some of the orcas' bullying tactics include pushing the porpoise along with their nose, holding the porpoise in their mouth, balancing the porpoise above water, slapping the porpoise with their tail, and raking the porpoise with their teeth, according to Science Alert. Killer whales also use porpoises as playthings as they catch them before letting them and proceeding to chase them once more - and they even play toss them around in a 'pass the porpoise' game, say whale watchers. That's some textbook tormenting. Out of these sightings, 28 of them have ended in the harbour porpoise (Phocoena phocoena) or a Dall's porpoise being suspected to have been killed, though there's no record of the porpoises being eaten by the orcas. In terms of size, the porpoise is said to be fairly small being a similar size to a Chinook salmon - a large fish species that can grow up to 1.5 meters (5 feet). There are three theories that have been considered by the experts. Firstly, the bullying is all about creating coordination, and cohesion within the group of orcas, or alternatively that the orcas do this as a form of hunting practice. The final theory is that orcas could be trying to look after weak porpoises as if they were their own aka 'displaced epimeletic behaviour.' This mismothering behaviour – also known as 'displaced epimeletic behaviour' to scientists – might be due to their limited opportunities to look after youngsters as the stat shows. "Our research has shown that due to malnutrition, nearly 70 per cent of Southern Resident killer whale pregnancies have resulted in miscarriages or calves that died right away after birth." It seems that orcas are not the only bullies of the seas, as smaller dolphins e.g. bottlenose have similarly been seen harassing and killing for no clear reason.

A top EU official has asked X/Twitter owner Elon Musk to “walk the talk” when it comes to curbing fake content and the glorification of violence following the terror attack against Israel by Hamas. EU commissioner Thierry Breton wrote in an open letter shared on X that illegal content and disinformation were being shared via the social media platform about the Hamas incursion into Israel, which began on Saturday. He warned the EU could punish X for failure to comply with its obligations to moderate content under the Digital Services Act, and gave Mr Musk 24 hours to give a “prompt, accurate and complete response”. “You need to be very transparent and clear on what content is permitted under your terms and consistently and dingently enforce your own policies,” Mr Berton said, adding that the social media company “must be timely, diligent and objective” in taking action and removing relevant content when it receives warranted notices of illegal content in the EU. “I therefore invite you to urgently ensure that your systems are effective, and report on the crisis measures taken to my team,” the EU commissioner said, calling for Mr Musk to respond within 24 hours. Replying to the statement, the Tesla chief called on the commissioner to “list the violations”. “Our policy is that everything is open source and transparent, an approach that I know the EU supports. Please list the violations you allude to on X, so that that the public can see them,” the multibillionaire posted on X. “You are well aware of your users’ – and authorities’ – reports on fake content and glorification of violence. Up to you to demonstrate that you walk the talk,” Mr Breton said in response to Mr Musk’s tweet. While X has claimed it was treating the ongoing crisis in Israel with its highest level of response, watchdog groups and the EU said misinformation and harmful content continue to flourish on the microblogging platform. X’s own safety team acknowledged there had been an increase in daily active users on X in the conflict area in the past couple of days, saying that there have been more than 50 million posts globally focusing on the weekend attack. “As the events continue to unfold rapidly, a cross-company leadership group has assessed this moment as a crisis requiring the highest level of response,” the team said. The struggle to find reliable news on the platform was exacerbated when Mr Musk himself flagged two accounts as “good” for “following the war”. Journalists, however, pointed out that these accounts had previously shared a fake AI-generated image of an explosion at the US Pentagon, and that one of them had also posted antisemitic comments. Mr Musk’s posts recommending them have now been deleted. Users on the platform also pointed out that old videos are being repackaged and circulated on X as if they are from the most recent attack. One widely shared video falsely claimed to show a Hamas militant shooting down an Israeli helicopter, but was later found to be a clip from a video game. “Public media and civil society organisations widely report instances of fake and manipulated images and facts circulating on your platform in the EU, such as repurposed old images of unrelated armed conflicts or military footage that actually originated from video games,” the Eu commissioner said in his letter addressing Mr Musk. X has not immediately responded to The Independent’s request for comment. Read More X promises 'highest level' response on posts about Israel-Hamas war.
