Well, now here is an interested little tidbit. It appears that herring use gas as a form of self-preservation. Researchers from British Columbia report that these fish use the noise produced by underwater farting to stay in large protective groups under the cover of darkness.
This intriguing idea comes from scientists who discovered that herring create a mysterious underwater noise by farting. Researchers suspect herring hear the bubbles as they’re expelled, helping the fish form protective shoals at night. It’s the first ever study to suggest fish communicate by breaking wind.
