What is "ethnoherpetology"

Ethnoherpetology is the study of the past and present interrelationships between human cultures and reptiles and amphibians. It is a sub-field of ethnozoology, which in turn is a sub-field of ethnobiology. Snakes and amphibians have been considered chthonic creatures in many cultures. Richly represented in mythology, culture, art, and literature, they often evoke revulsion, fear, suspicion and awe, sometimes even hysteria. Frogs and toads were believed to announce the rains with their choruses.
