About the Cropan's Boa
Corallus cropanii, or Cropani's tree boa, is a species of boa, a snake in the family Boidae. The species is endemic to the state of São Paulo, Brazil. Like all boas, it is not venomous. No subspecies are currently recognized. Until 2017, no specimen of this snake had been seen alive since 1953 and only five dead specimens had been collected since then, but in late January 2017, an adult female Cropan's tree boa measuring 1.7 m was captured by locals in Sete Barras, São Paulo who brought it to herpetologists from the Instituto Butantan and the Museum of Zoology of the University of São Paulo, who radio-tagged and released the animal to learn more about the species' behavior.
