The broad-banded copperhead is a venomous pit viper, a type of snake that uses heat-sensing pits between its eyes and nostrils to find prey. It lives in the central United States, mainly Oklahoma and central Texas, and in parts of northern Mexico. For a long time it was thought to be a form of the eastern copperhead, but it is now treated as its own species.1

It lives in lightly wooded areas with plenty of ground debris for cover, not far from a permanent water source. It is secretive and active at night, and it tends to avoid areas with many people.1

Què menja?
It is a diet generalist, but small rodents such as rats and mice make up most of what it eats. It is mainly an ambush predator that finds prey using smell, sight and heat. It usually bites larger prey and lets the venom work, but it holds birds and smaller prey until they die.1

Com reconèixer-lo

  • Typically light tan with wide, darker brown crossbands, which give it its common name.1
  • Colour varies by location, from red-brown to grey-brown.1
  • The bands stay even in width. The eastern copperhead's bands narrow at the spine to form hourglass shapes.1
  • Young snakes have a bright green-yellow tail tip that fades to grey or brown at about one year old.1

Sovint es confon amb: The eastern copperhead overlaps with this species in the south of its range, and the two can be hard to tell apart there. Look at the bands: the broad-banded copperhead has even bands, while the eastern copperhead's bands narrow at the spine.1

Poder del verí

Mossegades

El verí surt pels ullals o les dents quan mossega.

Què fa el seu verí?

Its venom is hemotoxic, meaning it mainly damages blood and tissue. It is injected through hinged, hollow fangs in a single quick strike. The bite can cause localised swelling, necrosis (death of tissue at the bite site) and severe pain.1

Perill per a les persones: GreuUna mossegada necessita un metge. Les morts són molt rares.

Copperhead venom is not considered life-threatening to an otherwise healthy adult. Any bite from a venomous snake should still be treated as serious.1

Bona notícia: els metges tenen un medicament (l'antiverí) o un tractament per a això.1

Si mossega

  • Any bite from a venomous snake should be treated as serious, and medical treatment should be sought. Doctors may use CroFab in severe cases, which is made using cottonmouth venom because no antivenin is made specifically for copperheads.1
  • Mantén la persona quieta i tranquil·la, mantén l'extremitat mossegada a l'altura del cor, treu-li anells i coses que estrenyin i porta-la de pressa a un hospital.

Truca sempre primer al número d'emergències (112, 000, 911). Això són pautes generals de primers auxilis, no consells mèdics. Primers auxilis bàsics

Estigues segur

  • No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
  • Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
  • Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.
