The black-tailed rattlesnake is a venomous pit viper that lives in the south-west of the United States and in Mexico. It is known as one of the calmest rattlesnakes, and it relies on camouflage rather than confrontation.1

Uning zahari (chaqsa yoki nish ursa) nima qiladi?

Its venom is primarily hemotoxic, meaning it mainly acts on the blood and surrounding tissue, as with most crotalids (pit vipers). It is only about two-thirds as toxic as western diamondback venom. Because the venom is weaker, the snake has larger venom glands than most rattlesnakes in its region and injects large quantities into prey.1

Odamlar uchun qanchalik xavfli?

Odamlar uchun xavf: JiddiyChaqqanda shifokor kerak. Oʻlim holatlari juda kam.

Bites are fairly rare, because the snake is considered one of the most docile rattlesnakes. The venom is generally not fatal to humans.1

Yaxshi xabar: shifokorlarda buning uchun dori (zaharga qarshi zardob) yoki davolash usuli bor.1

Qoʻrqqanda nima qiladi?

It normally tries to slither away when confronted, but it will rattle when cornered, and it relies mostly on camouflage to avoid discovery.1

CroFab antivenom is often used to treat bites from this snake.1

Faktlar

Its venom glands are larger than those of most rattlesnakes in its region, which compensates for its weaker venom.1

It is considered one of the most docile rattlesnakes because of its calm demeanour and curious nature.1

In the spring and fall it is mainly active during the day, but in summer it becomes nocturnal to avoid the heat.1

In winter it hibernates in dens made and abandoned by other animals, often sharing them with other snake species.1

Its lifespan averages 15 to 20 years.1

Afsonalarni fosh qiluvchi

Afsona: The number of segments in a rattle shows how old a rattlesnake is.

Haqiqat: Each time the snake sheds its skin, a new segment is added. Snakes can shed several times a year, and the rattle is fragile and can break, so its length is not an accurate guide to age unless the tip (terminal button) is intact.1
