Corallus cropanii, or Cropan's tree boa, is a non-venomous boa species found in the state of São Paulo, Brazil. No subspecies are currently recognized. Until 2017, no specimen of this snake had been seen alive since 1953 and only three to six specimens were collected.

However, in late January 2017, an adult female Cropan's tree boa measuring 5.5 ft (1.7 m) was captured by locals in Ribeira who brought it to herpetologists from the Butantan Institute and the University of São Paulo Museum of Zoology, who radio-tagged and released the animal to learn more about the species' behavior.

Cropan's boa inhabits a forest range in Brazil and scientists recently glimpsed the first living specimen seen since 1953. Brazil's elusive tree boa Corallus cropanii also known as Cropan's boa - is one of the world's rarest snake species infrequently sighted and known from only a handful of dead specimens collected.

The boa sparked much interest and Live Science relayed that scientists developed the outreach program to raise local awareness for the Cropan's boa so that it can educate  the community about the snake's ecological importance and to encourage them to help biologists learn more about its habits.

The snake will be studied in order to discover more information about its biology and habits. As it has never been observed in nature, we do not have much information about its behavior.
