Not Only Do Fish ‘Talk,’ They Have Accents

Not only do cod “speak” to each other, but they have “regional fish accents”-kind of like the aquatic version of a southern drawl-and that could be bad news for fish-and-chips lovers, Wired reports. According to the Boston Globe, marine biologist Steve Simpson recently started a two-year project to study the sounds surrounding cod. Cod “speak” by vibrating their swim bladders, but the noises they make vary based on where their breeding grounds are located. For example, US cod make a “deep thumping sound,” while cod in Norway make a “higher-pitched sound, with a long growl,” USA Today reports. Similar “regional dialects” have been detected in birds and various mammals, including, obviously, humans.
