Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

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

Gaano ito kapanganib sa tao?

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

Magandang balita: may gamot (antivenom) o gamutan ang mga doktor para dito.1

Ano ang ginagawa nito kapag natatakot?

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

Kung kumagat ito

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

Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact

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

Myth buster

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

Totoo: 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
