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

Zer jaten du?
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

Nola ezagutu

  • 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

Askotan honekin nahasten da: 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

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zein arriskutsua da pertsonentzat?

Arriskua pertsonentzat: LarriaKoska batek medikua behar du. Heriotzak oso arraroak dira.

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

Zer egiten du beldurtzen denean?

It often freezes instead of fleeing, relying on its camouflage, and may vibrate its tail when closely approached.1

Kosk egiten badu

  • Eutsi pertsona geldi eta lasai, eduki koska jasotako gorputz-adarra bihotzaren mailan, kendu eraztunak eta gauza estuak, eta joan ospitalera azkar.

Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak

Egon seguru

  • Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
  • Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
  • Batek kosk egiten badizu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

Datuak

1

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

2

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

3

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

4

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

5

Its venom has potential medicinal value to humans.1

6

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

Mito-hauslea

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

Egia: 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
