A subfamily of snakes that includes most of the harmless and mildly venomous snakes found worldwide, characterized by their simple tooth structure and lack of specialized venom delivery systems.
From Latin 'colubra' (snake) plus the taxonomic suffix '-inae' denoting a subfamily. The Latin root likely derives from Indo-European, connecting to various ancient words for serpents. This scientific naming convention became standardized in the 18th century for biological classification.
Colubrinae is the largest snake subfamily with over 2,000 species, yet many of these 'harmless' snakes have recently been found to have mild venom—a discovery that's forcing scientists to rethink how dangerous a snake really needs to be to count as venomous.
