I can&#x27;t find any high-quality single page that gives the history, but here&#x27;s a low-quality one that explains the connection: <a href="http:&#x2F;&#x2F;twistedphysics.typepad.com&#x2F;cocktail_party_physics&#x2F;2007&#x2F;06&#x2F;running_hot_and.html" rel="nofollow">http:&#x2F;&#x2F;twistedphysics.typepad.com&#x2F;cocktail_party_physics&#x2F;200...</a><p>Basically, pistol shrimp &quot;attacks&quot; produce a small burst of light (sonoluminesence).   There was a theory that this was actually a form of fusion (sonofusion).  There were some studies done that demonstrated this (Taleyarkhan, 2002).  But there were lots of irregularities about the study (Naranjo, 2006), and like cold fusion it&#x27;s been (mostly?) discredited.
