In 2004 News of the Weird reported research suggesting that herring routinely communicate among themselves via a high-pitched, "raspberry"-like sound emitted from the anus. In June 2006, a researcher at Greenland Institute of Natural Resources said that herring appear also to use anal bubbles as a defense to obscure themselves from killer whales. (Researchers are not agreed on whether it is digestive gases or some other mechanism that produces the bubbles.) [Discovery Channel News, 6-20-06]
