Watching the Animal Planet channel recently I saw a feature on herring, in which it was claimed that they deliberately 'break wind' in the water in order to communicate. Note that I remember from my schooldays that the plural of herring is indeed herring! So these emissions from behind are known in the science world as Fast Repetitive Ticks, FRT's for short. Surely not! This has got to be some kind of April fool! However, upon reading this article and a few more I discovered on the web, this claim has just got to be truthful.
