This symbol to abstain comes from the hicatee (ひか) turtle. The hicatee is a Central American river turtle hunted for its meat, eggs, and shell. Therefore, the poor hicatee are endangered. So people started to rally around them, abstaining from hurting them anymore. They raised their fingers to the sky and shouted, "I abstain from harming these hicatee!"
