Question: are there snakes in santorini?
Answer: Locals say that Sanotrini has venomous snakes, but I just received an update from herpetofauna.gr, that in fact there are only two snakes on Santorini, the Leopard Snake (Zamenis situla) and the Cat Snake (Telescopus fallax). The animal of the photo is a Cat Snake. Both of them are completely harmless to humans.
