The Texas coral snake is a venomous snake with bright black, yellow and red rings. It lives in the southern and southwestern United States and in parts of northeastern and central Mexico. Its bite can cause paralysis, so it is important to recognise it and keep well away.1

Nola ezagutu

  • Black, yellow and red rings, with the rings running onto the belly.1
  • Smooth scales, a rounded head and round pupils.1
  • Somewhat larger and stouter than the eastern coral snake.1
  • Males are typically smaller than females.1
  • Shy and secretive, and mostly active at night.1

Askotan honekin nahasten da: Nonvenomous snakes copy the coral snake's colours as a form of Batesian mimicry. In the United States, the venomous coral snakes can be told apart by red rings touching yellow rings. The common rhyme "red and yellow, kill a fellow" is not always accurate because colours vary, and relying on it is dangerous.1

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

The snake has a pair of fixed, grooved fangs at the front of the upper jaw, and venom is injected through them. Its venom contains a neurotoxin, which attacks the nerves, and a myotoxin, which damages muscle. Bite victims may experience paralysis or myolysis (muscle breakdown), which can be potentially lethal.1

Before antivenom was available, the fatality rate of coral snake bites was estimated at 10%. Deaths were mainly caused by breathing or heart failure from paralysis. A single bite can deliver 10–12 mg of dry venom, about twice the lethal dose for an adult human of 5–7 mg. Many bites deliver no venom at all, known as dry bites.1

Zer egiten du beldurtzen denean?

When grabbed suddenly, or sometimes just when touched, it may thrash about, swing around and bite.1

Kosk egiten badu

  • Remove any jewellery from a bitten limb, in case of severe swelling. Wrap the bite area moderately tightly in a wide cloth, and move the bitten limb as little as possible. Take the bite victim to the nearest hospital as soon as possible for advanced treatment, such as antivenom.1
  • Eutsi pertsona geldi eta lasai eta joan ospitalera azkar, koska txikia dirudien arren: sintomak ordu batzuk geroago has daitezke.

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

A single bite can deliver about twice the lethal dose for an adult human, yet many bites inject no venom at all.1

2

The Texas coral snake eats other snakes, including venomous ones, and will even eat its own kind.1

3

Colour variants exist in the wild, including albino, anerythristic, pastel and completely black (melanistic) snakes.1

Mito-hauslea

Mitoa: "Red and yellow, kill a fellow. Red on black, friend of Jack" is a reliable way to tell a coral snake from a harmless look-alike.

Egia: The rhyme is not always accurate because colour patterns vary, and relying on it is dangerous to both people and snakes.1
