The eastern diamondback rattlesnake is a pit viper that lives in the southeastern United States. It is the largest rattlesnake species and one of the heaviest venomous snakes in the Americas. Its diamond-patterned back and loud rattle make it easy to recognise, and it is widely regarded as one of the most dangerous venomous snakes in North America.1

Otrovna snaga

Ugrizi

Otrov izlazi kroz očnjake ili zube kad ugrize.

Što radi njegov otrov kad ugrize ili ubode?

Its venom contains more than 100 different toxins, and about 40 have been identified, making it one of the most studied snake venoms. The venom contains a thrombin-like enzyme called crotalase, which clots fibrinogen, a protein needed for blood clotting. The estimated human lethal dose is 100 to 150 mg.1

It has a reputation as the most dangerous venomous snake in North America. It is not usually aggressive, but it is large and powerful. Reported mortality from untreated bites is 10 to 20% in some studies and 30% in another, and it is a major cause of fatal snakebites within its range.1

Što radi kad se uplaši?

When threatened, it raises the front half of its body in an S-shaped coil, rattles loudly, and can strike to at least a third of its body length.1

Ako ugrize

Neka osoba miruje i bude smirena, drži ugriženi ud u visini srca, skini prstenje i sve što steže i brzo je odvedi u bolnicu.

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti
