Species of snake

Trimeresurus macrops Trimeresurus macrops - Khao Yai National Park, Thailand Conservation status Least Concern (IUCN 3.1)[1] Scientific classification Kingdom: Animalia Phylum: Chordata Class: Reptilia Order: Squamata Suborder: Serpentes Family: Viperidae Genus: Trimeresurus Species: T. macrops Binomial name Trimeresurus macrops Kramer, 1977 Synonyms Trimeresurus macrops Kramer, 1977[2] Cryptelytrops macrops – Malhotra & Thorpe, 2004 Trimeresurus (Trimeresurus) macrops – David et al., 2011[3]

***Trimeresurus macrops*** is a [venomous](/source/Venomous_snake) [pit viper](/source/Crotalinae) [species](/source/Species) [endemic](/source/Endemism) to [Southeast Asia](/source/Southeast_Asia). No [subspecies](/source/Subspecies) are currently recognized.[4] Common names include **large-eyed pitviper**,[5] **green pit viper**, and **Kramer's pit viper**.[6]

## Description

It can be distinguished from other green pit vipers by the relatively large size of its eyes, which is especially noticeable in adult specimens, and to which the [specific name](/source/Specific_name_(zoology)), *macrops*, refers.[3]

## Breeding

According to Strine, Green pit vipers mate during the end of the rainy season, between September and October.[7] Female vipers will pull male vipers up the tree and begin mating.

## Geographic range

It is found in [Southeast Asia](/source/Southeast_Asia) in northern [Cambodia](/source/Cambodia), [Laos](/source/Laos), [Thailand](/source/Thailand), and southern [Vietnam](/source/Vietnam).[3] The [type locality](/source/Type_locality_(biology)) given is "[Bangkok](/source/Bangkok), Thailand".[2]

## Venom

*T. macrops* belongs to the genus *[Trimeresurus](/source/Trimeresurus)*, a group of Asian vipers with primarily [hemotoxic](/source/Hemotoxin) venom — a type of venom that can destroy blood cells, disrupt blood clotting, and damage organ function. A bite from this viper's better-studied cousin, the [white-lipped pit viper](/source/Trimeresurus_albolabris), is said to cause effects ranging from mild envenomation to death.[8] The broader viper family, [Viperidae](/source/Viper), includes some of the deadliest snakes in the world, responsible for more human fatalities than any other type of snake.
