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

Ano ang epekto ng kamandag nito?

Its venom is extremely potent and can be haemorrhagic (damaging blood vessels and causing bleeding) or neurotoxic (attacking the nerves), depending on the population and location. Its long fangs, large size and high venom yield make it potentially one of North America's most dangerous snakes. Venom-induced incapacitation can progress rapidly.1

Gaano ito kapanganib sa tao?

Panganib sa tao: NapakapanganibKaya nitong pumatay ng taong hindi nagamot.

It is potentially one of North America's most dangerous snakes, but it is usually shy and calm. It will retreat if it can and attacks mainly when cornered. Over many years in western Pennsylvania, one naturalist heard of only one death from its bite. Bites are widespread in some areas of Iowa's forests. Its remote, wooded habitat can make emergency medical care difficult or even impossible.1

Ano ang ginagawa nito kapag natatakot?

It rattles and feints a good deal before striking, and it will try to retreat first if it feels threatened.1

Kung kumagat ito

Panatilihing hindi gumagalaw at kalmado ang tao, panatilihin ang nakagat na braso o binti sa antas ng puso, tanggalin ang mga singsing at masisikip na bagay, at pumunta agad sa ospital.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

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

Timber rattlesnakes return to the same winter den each year, and juveniles can track chemical cues to find relatives in it.1

Female timber rattlesnakes bask in the sun on open rocky areas called basking knolls before they give birth.1

They share winter dens with copperheads and rat snakes.1

It is the only rattlesnake in most of the populous Northeastern United States, and one of the most northerly venomous snakes in North America.1

Males often mate farther from the winter dens than females do.1

Myth buster

Mito: Rattlesnakes attack people as soon as they see them.

Totoo: Timber rattlesnakes are shy and will try to retreat from danger first. They attack mainly when they are cornered, so leaving them alone keeps people safe.1
