The eastern copperhead is a venomous pit viper that lives across much of the eastern United States. It has hourglass-shaped bands on a tan or reddish-brown body, which help it hide in leaves and clay. It is common, so people sometimes meet it without realising, and it makes up half of the treated snake bites in the United States.1

It favours deciduous forest and mixed woodlands in most of its range, and often sits on rock outcroppings and ledges. It is also found in low-lying, swampy areas. Bites happen when people step on or near it, especially where it lies hidden in dead leaves or red clay.1

Kaj je?

It eats a wide range of prey, including insects, spiders, lizards, frogs, mice and small birds. It is mainly an ambush predator that waits in a good position for prey to arrive, though it actively hunts insects. It uses facial pit organs to sense heat and make accurate strikes.1

Kako jo prepoznaš

Dark brown, hourglass-shaped crossbands on a light reddish-brown or brown background1
A heavy, stout body rather than a slender one1
A broad head that is distinct from the neck1
Young have green or yellow tail tips, which darken to brown or black within a year1
Adults are typically 50 to 95 cm long, including the tail1

Pogosto zamenjujejo z: The snout slopes down and back, so it looks less blunt than the snout of the cottonmouth. The head also extends further forward than the mouth.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: ResnoPo ugrizu je potreben zdravnik. Smrtni primeri so zelo redki.

Copperhead bites account for half of the treated snake bites in the United States. Bites usually happen when people unknowingly step on or near the snake. It is generally nonaggressive and will strike only if threatened as a last resort.1

Kaj naredi, ko se prestraši?

It often freezes instead of fleeing, relying on its camouflage, and may vibrate its tail when closely approached.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.

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

Dejstva

Its tail can vibrate more than 40 times per second, faster than almost any non-rattlesnake snake.1

Juveniles wave a brightly coloured tail to attract frogs and perhaps lizards, a behaviour called caudal luring.1

Its camouflage is so good that it can be almost impossible to see on dead leaves or red clay.1

In Texas, copperheads have been found in bushes, vines and trees up to 12 metres above the ground, seeking newly emerged cicadas.1

Its venom has potential medicinal value to humans.1

Historically, kingsnakes were major predators of copperheads, and recent copperhead numbers have risen where kingsnake populations have declined.1

Mit: Copperheads are aggressive snakes that chase people and go looking for trouble.

Resnica: They are generally nonaggressive. They usually freeze or flee, and they strike only if threatened as a last resort. Most bites happen when people step on or near them without noticing.1
