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

It hunts small mammals, especially rabbits and rice rats, and also eats birds. It either actively searches for prey or waits coiled in ambush for up to a week. After striking and releasing its prey, it follows the scent trail the dying animal leaves.1

Kako jo prepoznaš

  • Dark brown to black diamond-shaped blotches on a brownish, grey or olive background, each outlined with cream or yellowish scales1
  • A dark stripe runs from behind each eye to the mouth corner, edged above and below by white or yellow stripes1
  • A rattle of hollow segments at the tail tip, which break off and are replaced when the snake sheds1
  • Five to ten bands around the tail, below the diamond pattern1
  • A large, heavy body, with adults often around 1.1 to 1.7 m long1

Kaj naredi njen strup, ko ugrizne ali piči?

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

Kaj naredi, ko se prestraši?

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

Če ugrizne

  • Poškodovanca drži pri miru in ga pomirjaj, ugriznjeni ud drži v višini srca, odstrani prstane in tesne stvari ter ga hitro odpelji v bolnišnico.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti
