Herring fart to communicate

Tiny bubbles that stream from their anuses in the dark may allow herring to keep in tight schools when they can't see.  Amusing, unlike human farts, herring farts seem to bring the fish closer together.

Herring farts are not gut gas, rather they come from air gulped at the surface and stored in their swim bladder (air-containing organ used to control buoyancy).
