The western diamondback rattlesnake is a large, venomous pit viper that lives in the southwestern United States and the northern half of Mexico. It is thought to cause most snakebite deaths in northern Mexico and more snakebites in the United States than any other snake. Its diamond-shaped back markings and loud rattle make it easier to recognise, but it should always be given plenty of space.1

Como recoñecelo

  • Usually khaki in colour, though it may also be pinkish, brick red, yellowish blonde or white.1
  • A row of 23 to 45 brown or dark umber blotches runs along the back, becoming diamond-shaped towards the middle of the body.1
  • The tail has two to eight black bands, usually four to six, separated by white or grey.1
  • A grey or umber stripe runs diagonally from the eye across the side of the head, usually edged below by a white stripe.1

It is thought to be responsible for most snakebite deaths in northern Mexico and for the greatest number of snakebites in the United States. It can deliver a large amount of venom in one bite.1

Que fai cando ten medo?

When threatened it usually coils and rattles to warn off attackers, and it is unusually willing to stand its ground. If rattling does not work, it will strike.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

2

A juvenile was once found dead after trying to swallow a horned lizard, whose horns punctured its gullet.1

3

It is likely the second largest rattlesnake species, behind only its close relative the eastern diamondback rattlesnake.1

4

It is one of the few snake species that scavenges for food.1

5

Among rattlesnakes, it may be the most adaptable to towns and suburbs, and it thrives deep within developed areas.1
