One strategy tends to be used with prey that an individual is less familiar with: a snake envenomates its prey and then retracts its head, allowing their venom to take effect and later retrieving and swallowing its prey. 2002. The infrared trigemino-tectal pathway in the rattlesnake and in the python. They also live in thickets, savannas, semitropical highland forests, as well as in cultivated fields with close vegetable openings, adults are mainly terrestrial, but juveniles are trees. They are considered semi-arboreal; adults are largely terrestrial, while juveniles are more arboreal, presumably to avoid predators. forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. [4], It inhabits mainly in the dense tropical perennial forests in the Atlantic Forest, about 1000 m above sea level. The specific name, jararaca, is derived from the Tupi words yarará and ca, which mean "large snake". All exhibit similarities, inculding fusion of the the supralabial scales anterior to the temporal scales. Generally, male-male fighting occurs in viperids, activated by the presence of sex steroids such as androgens and estrogens, prior to copulation.

Researchers found the venom of Brazilian pit vipers to contain a peptide that caused a severe drop in blood pressure in mice; it was used in the development of the first angiotensin converting enzyme inhibitors, for treatment of people with hypertension and congestive heart failure. Juveniles most often have a light tip on their tails, used for caudal luring of prey. These snakes are sexually dimorphic, with females larger than males; females also produce significantly more (220 mg vs 40 mg), and more lethal, venom than males. Martins, M., O. Marques, I. Sazima. These snakes may also help to keep populations of agricultural pests, such as rodents, in check. active during the day, 2. lasting for one day. [7], Mating takes place between April and May, males mate with more than one female, and there are also fights between males for the female. Venom composition varies significantly between males and females, with male venom containing more protein diversity.
