The study's findings, now published online in the U.K. science journal Biology Letters, reveal that Atlantic and Pacific herring create high-frequency sounds by releasing air from their anuses.But, can they burp Jingle Bells?
"We know [herring] have excellent hearing but little about what they actually use it for," said research team leader Ben Wilson, a marine biologist at the Bamfield Marine Science Centre, British Columbia, Canada. "It turns out that herring make unusual farting sounds at night."
Wilson and his colleagues named the phenomenon Fast Repetitive Tick, which makes for the rather mischievous acronym, FRT. But unlike the human version, these FRTs are thought to bring the fish closer together.
