Indeed, Green saw a few instances where a winner would strike a fleeing loser in the abdomen rather than the telson, puncturing its shell and inflicting severe injuries. Researchers since the 1960s have proposed a number of theoretical models to describe the mental calculus animals use to decide when to give up a fight. As Douglas Emlen from the University of Montana writes in his book Animal Weapons, In one of natures more amusing paradoxes, the most extreme weapons are also the least likely to be deployed in pitched battle..
