Trimeresurus cantori, commonly known as Cantor's pit viper[4] or Cantor's pitviper,[5] is a species of venomous snake, a pit viper in the Subfamily Crotalinae of the family Viperidae.

[6] It was named after Theodore Edward Cantor (1809-1860), a Danish naturalist serving as a surgeon with the East India Company in Calcutta.

Running along each side of the head, below the eye and above the upper lip, is a cream-colored stripe.

[9] The preferred natural habitat of T. cantori is forest, at altitudes from sea level to 200 m (660 ft), but it has also been found in coconut plantations and rural gardens.

[8] The species T. cantori possesses a potent venom, and some of its bites to humans have resulted in fatalities.
