There's rarely time to write about every cool science-y story that comes our way. So this year, we're once again running a special Twelve Days of Christmas series of posts, highlighting one science story that fell through the cracks in 2022, each day from December 25 through January 5. Today: Scientists attached video cameras onto dolphins to capture the sights and sounds of the animals as they hunted for prey to learn more about their feeding behavior.

Scientists attached GoPro cameras to six dolphins and captured the sights and sounds of the animals as they hunted and devoured various species of fish—even squealing in victory at the capture of baby sea snakes, according to an August paper published in the journal PLoS ONE. While sound and video has previously been recorded for dolphins finding and eating dead fish, per the authors, this is the first footage combining sound and video from the dolphins' point of view as they pursued live prey while freely swimming. The audio element enabled the scientists to learn more about how the dolphins communicated while hunting.
