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

Que come?
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

Como recoñecelo

  • 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

Adoita confundirse con: 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

Que perigoso é para as persoas?

Perigo para as persoas: GraveUnha mordedura precisa un médico. As mortes son moi raras.

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

Que fai cando ten medo?

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

Se morde

  • Mantén a persoa quieta e tranquila, mantén o membro mordido á altura do corazón, quítalle aneis e cousas apertadas e vai rápido a un hospital.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te morde: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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

Desmontamitos

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

Verdade: 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
