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.

Marcelo Bielsa has been appointed as Uruguay head coach. The 67-year-old had been out of football management since leaving Leeds almost 15 months ago. The Uruguayan Football Association confirmed Bielsa’s appointment on a deal running until the 2026 World Cup. He succeeds Diego Alonso as national team boss. Alonso’s contract expired after the World Cup in Qatar earlier this season, where Uruguay suffered a shock group-stage exit. Bielsa served as manager of Argentina from 1998 to 2004 and he also had a four-year stint in charge of Chile. Bielsa guided Leeds back to the Premier League from the Championship in 2020 and was one of the most popular managers in the club’s history. But he left in February last year following a run of four successive league defeats. His lengthy managerial career has also included spells with Athletic Bilbao, Marseille and Lille. Uruguay are currently 16th in FIFA’s world rankings, with Bielsa’s first major campaign at the helm set to be next year’s Copa America in the United States.

Northern Ireland had a stoppage-time equaliser ruled out by VAR as a battling display went unrewarded in a 1-0 Euro 2024 qualifying loss to Denmark. Jonas Wind’s goal early in the second half made the difference in Copenhagen as debutant Callum Marshall saw a dream goal ruled out for offside after a review which took almost five minutes. The West Ham youngster flicked the ball in after Jonny Evans headed on a free-kick, but there was despair when referee Daniel Stefanski eventually signalled for offside after his colleague Tomasz Kwiatkowski took an age to review the footage. Michael O’Neill’s men defended doggedly away to the top seeds in Group H, but a mistake just two minutes after the break proved decisive as Denmark bounced back from March’s shock defeat to Kazakhstan and put the pressure on Northern Ireland to deliver when the Kazakhs visit Windsor Park on Monday. Wind pounced when Ciaron Brown got it all wrong trying to deal with Joakim Maehle’s short cross in from the left, slamming the ball home from close range. But O’Neill will take encouragement from how a youthful line-up dealt with the hardest fixture in Group H. Before kick-off came news that Craig Cathcart had suffered a back injury, taking the number of first-team regulars missing to 10, a figure threatening to derail this qualifying campaign even before the halfway stage. Trai Hume made his first start at left wing-back, with Evans between Brown and Paddy McNair at the back. Also making his first start was Isaac Price, one of three teenagers in the side along with Conor Bradley and Shea Charles. O’Neill was well aware of what he was asking of such inexperienced players in the raucous atmosphere of the Parken Stadium, and watched on as they soaked up huge amounts of pressure before the break as Denmark grew frustrated. Andreas Skov Olsen’s early cross was slightly behind Pierre-Emile Hojbjerg, who twisted acrobatically to make contact but could not find the target. Christian Eriksen sent a free-kick from long range wide, while the clearest chance came to Crystal Palace defender Joachim Andersen just before the half hour as space opened up in front of him, but his powerful shot was straight at Bailey Peacock-Farrell. Shayne Lavery, selected ahead of Dion Charles in attack, worked tirelessly to offer an outlet as he and the slender figure of Price, asked to play in an advanced role, faced up to Denmark’s imposing back three of Simon Kjaer, Andreas Christensen and Andersen. It was Lavery who had Northern Ireland’s only first-half opportunity when Price laid the ball off on the edge of the area. Lavery looked up to see three defenders closing in, but got off a deflected strike which Kasper Schmeichel was able to gather. But after all that hard work in the first half, Denmark needed only two minutes of the second to find the breakthrough thanks to a mistake at the back. Northern Ireland did not recover their shape after Bradley lost the ball, and when Brown stumbled to the floor, Wind accepted the gift. A set-piece offered Northern Ireland an opportunity but Price and Lavery got their wires crossed trying to play it short and Denmark broke, with Peacock-Farrell saving smartly from the in-demand Rasmus Hojlund, scorer of five goals in the first two qualifiers. Quick distribution from Peacock-Farrell set Price free down the right as the hour mark approached, but with no support the teenager had to test Schmeichel from a tight angle, forcing a corner. It looked as though there was a late twist when Marshall, on for Ali McCann with five minutes left, turned the ball home from close range, but VAR would kill the celebrations. Just three games into the qualifying campaign, it feels as though Northern Ireland must now deliver a result at home on Monday to keep themselves in the mix.
