These orcas are picking and shaping kelp stalks to roll over their bodies, a practice that takes place over an extended period.<br \/>Scientists from the Center for Whale Research (CWR) and the University of Exeter observed this behavior across all ages of a population in the <strong>Salish Sea<\/strong>. The precision of drone images has enabled these observations on a population that has been studied for over 50 years.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/www.europesays.com\/us\/wp-content\/uploads\/2025\/07\/orca_cetacean-1024x683.jpeg\" alt=\"\"  \/><\/p>\n<p>This practice could play a role in stress relief, social relationships, or skin health in these cetaceans, the researchers suggest. \u00a9 Stephen Walker, Unsplash<\/p>\n<p>A Social and Health Function<\/p>\n<p>These orcas don\u2019t simply find seaweed to use; they modify it, shaping it into something new, says Michael Weiss, CWR\u2019s research director. This behavior could serve multiple purposes, including reducing stress, enhancing social bonds, and maintaining skin health. The kelp\u2019s firm yet flexible nature makes it ideal for grooming, with its slippery outer surface acting like a hose.<\/p>\n<p>Social Needs, Not Just Health<\/p>\n<p>While animals generally use tools for food, this unique use of seaweed by orcas may point to something more. Darren Croft from the University of Exeter suggests it could be about social challenges, with the orcas using this tool to foster <strong>meaningful social interactions<\/strong>\u2014something crucial to their well-being.<\/p>\n<p>A Cultural Behavior in Danger<\/p>\n<p>This behavior may be a cultural trait unique to the Southern Resident orca population, which now has only 73 individuals remaining.
