They said it shows how a gray whale\u2019s movements \u2013 including forward and side-swimming, headstands and the use of \u201cbubble blasts\u201d \u2013 change as whales age and grow.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"KHXOBFNR2FAQPDAQBHFKVL3M7U\">Younger, smaller whales tend to use forward swimming behaviors while foraging and older, larger animals are more likely to use a head-down position called a headstand to push their mouths into the ocean floor, said researcher Clara Bird.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"MY4Q4FRNO5CXJCSYKVSXCK3DOU\">\u201cOur findings suggest that this headstanding behavior requires strength and coordination. For example, we often see whales sculling much like synchronized swimmers do while they are headstanding. It is likely this behavior is learned by the whales as they mature,\u201d Bird said.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"N43JRK56BBHZBGBXTTXXKOTFIQ\">The new study shows that whales change foraging tactics depending on the habitat and depth of the water. For example, they\u2019re more likely to use headstanding on a reef because their primary prey, mysid shrimp, tend to aggregate on reefs with kelp, Bird said.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"2QTYG24VFFHUNCZUUEXO4DAP3I\">The study also reveals why the whales perform \u201cbubble blasts,\u201d big single underwater exhales that produce large circle patterns at the surface.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"3E73PPKQYVGVTF5RW3GXVD5QHI\">Larger, fatter whales were more likely to bubble blast, researchers said, especially while performing headstands.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"GYA5DHIW3BAFPLY6QGSGNPVAIU\">It was previously thought that bubble blasts help gray whales capture prey, but the study shows the blasts are a behavioral adaptation used by the whales to regulate their buoyancy while feeding in very shallow water.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"JGPO47SVVFHJ5I3GONUJ3NQWLQ\">The research focused on a 200-member subgroup of gray whales that spend their summers feeding off the coast of Oregon, Washington, northern California and southern Canada rather than traveling north to the Arctic as most of the 19,000 gray whales in the Eastern North Pacific population do.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"UI5PRCMUFFFI5IZSGLO5RQUEVI\">The whales that don\u2019t travel north face elevated exposure to human activities \u2013 boat traffic, noise and pollution \u2013 while they feed in the shallow waters along the Pacific Coast, Bird said.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"5RXD7NOGRNBGXCSQ2ORH5FWDWA\">Researchers say the findings, published in the journal <a href=\"https:\/\/u7061146.ct.sendgrid.net\/ls\/click?upn=u001.gqh-2BaxUzlo7XKIuSly0rC-2BvNq-2BEVElHdHIsD4k0HAlOJIZ4qNGBgUAZHK3wj7Eqoa8gj8-2BRBSidlCwFPSEZr-2Fy0F4jBx9xVcTBMp26sO24k-3DGTfM_PkqgrhUdso5pVHC9YCDhekoTeLzBDXRFY2Ph-2B7tSLd60xCB88KcgBnHDDsj1BmJhoUOFUhWoYPqCCuNrjQ86n3GekhhRHtwv9TwrnubPl18r4zx7AaMbTYjFDmFsjii-2F1jxlLtu8idea3O9wPHxtXrEtapMvzQCbDzWkVpwBYUuL9yZgwEhcwLe3nfhzAstWhMjAgMlcmivYBmiSaBEjrYrKStB7gS8ae4DdSE4vaBzAyKda6TTjHZ0GVe1i2DXXNw5It5Y10EH4lye1E34waW2nu3cnpKV5-2BNK-2F07JIJ-2B3su6eaxP9M2XZADeeA9pM54aC1LBgokZTIj-2FWlNuBGIEE7oNSQHMzqAW-2FKvZzG8dw-3D\">Animal Behaviour<\/a> and in <a href=\"https:\/\/u7061146.ct.sendgrid.net\/ls\/click?upn=u001.gqh-2BaxUzlo7XKIuSly0rC-2FW-2BX920Ks7rgiNySgksznvSqRl7O-2BVXLKHOYuew4Jt6v4UFIikP0KfRkk9XDE9k5tj3-2BMmcs-2FJnQGMAvMSPJKU-3Dt2sb_PkqgrhUdso5pVHC9YCDhekoTeLzBDXRFY2Ph-2B7tSLd60xCB88KcgBnHDDsj1BmJhoUOFUhWoYPqCCuNrjQ86n3GekhhRHtwv9TwrnubPl18r4zx7AaMbTYjFDmFsjii-2F1jxlLtu8idea3O9wPHxtXrEtapMvzQCbDzWkVpwBYUuL9yZgwEhcwLe3nfhzAstWhMjAgMlcmivYBmiSaBEjrct2c9eHzqfVWrSahTRKdUA2HbXMeJNXCk-2B2zAeL8hXOIx77CIT-2FcOp8IpX79HDA9QLr1qeFRlIqUG6OCPjUMjS4ArPYkQo4qlAIAbm2XhxpM5JN8A9tROBc7RbZvZHQho71pHpac-2BZd6kPK7glfMqg-3D\">Ecology and Evolution<\/a>, can help protect the whales in the future.<\/p>\n<p class=\"article__paragraph article__paragraph--left\" id=\"JKIRTUG66FFCPBJKL2KK3OAOCE\"><i>\u2014 Gosia Wozniacka covers environmental justice, climate change, the clean energy transition and other environmental issues.
