Trimeresurus sumatranus is a species of venomous pitviper (a subfamily of vipers within the larger Viperidae family) found in the tropical forests of Indonesia, Malaysia and Thailand. Arboreal by nature, its coloration is pale to neon-green, with some black vertical markings, and a red-tipped tail. As with other vipers, this species has prominent, "keeled" scales, which appear somewhat raised and give the snake a rough-textured appearance. Common names include Sumatran pitviper, Sumatran tree viper, and Sumatran pit viper. Wikipedia →
