Besides laying eggs (most of them) and having their metabolism regulated by the environment, they’re all “herps;” that is, they’re all studied in the science of herpetology and so they’re the focus of the annual surveys by the Virginia Herpetological Society (VHS).
Every year the VHS conducts several surveys, some restricted to VHS members and others open to volunteers. VHS information on their 2017 surveys and on other VHS activities is available online at http://www.virginiaherpetologicalsociety.com.
For an audio take on the VHS’ 2017 “Herp Blitz,” have a listen to Virginia Water Radio Episode 371 (6-5-17).
