The eyes are characterized by a greenish iris ==Distribution and habitat==

Trimeresurus davidi is endemic to Car Nicobar Island, part of the Nicobar Archipelago in the Indian Ocean. This restricted range makes the species particularly vulnerable to environmental changes and habitat loss. The viper is arboreal, meaning it primarily inhabits trees, which is typical of many species within the Trimeresurus genus. ==References==
