This may sting a little: Scorpions have about 10,000 more genes than humans do.

The Chinese golden scorpion, Mesobuthus martensii, has at least 32,016 genes, Zhijian Cao of Wuhan University in China and colleagues report October 15 in Nature Communications. Humans have just over 22,000 genes.  

The researchers found 116 genes that encode neurotoxins, including 45 previously unknown ones. Many of the neurotoxins paralyze proteins in cell membranes that open and close to generate electrical signa...
