I was reading a post below regarding sexual dimorphism in rattlesnakes. For those of those interested in sexual dimorphism in Crotalus atrox here is some of the information that is in the literature. Dr. Emily Taylor has been presenting her data at SSAR on this from 2002-2005 as well as other places by invitation if I remember correctly. If you are serious about learning about sexual dimorphism in Crotalus atrox, I suggest you read these.
