As a pit viper, they have heat-sensing infrared pits between eyes and nostrils to sense their prey. They are divided into three species. The 2.0 to 2.4 metres long snakes are yellow, red or brown with dark blotches. They love cool and moist tropical forests and eat small mammals and birds. They are one of the few vipers that lay eggs.
