The Fanged Fish That Drugs Its Enemies With Opioids
Not unlike the ant-decapitating fly and the satanic leaf-tailed gecko, the fang blenny\u2019s name does not disappoint. This tiny fish wields two massive teeth that it uses to gouge chunks out of much larger fish and, in a bind, scrap its way out of the grasp of a predator. And one particular group of fang blenny even injects venom, just like a snake, to give its attackers that extra what-for. That\u2019s all very, very bizarre behavior for a fish\u2014behavior that today gets even more bizarre.
