Tiger rattlesnake
The tiger rattlesnake is a small rattlesnake with a very venomous bite. It lives in the deserts and rocky hills of the southwestern United States and northwestern Mexico. Its venom is among the most toxic of any rattlesnake, so it is important to recognise it and give the right first aid after a bite.1

Cómo reconocerlo
- It has a small, spade-shaped head. It is the smallest head of any rattlesnake, and it is about 1/25 of its total body length.1
- It has 35 to 52 narrow gray, olive or brown crossbands along the back. These are the only crossbands on the front part of a rattlesnake's body, and they can look like vertical stripes from the side.1
- The ground colour is gray, lavender, blue-gray, pink or buff, and it often turns pink, pale orange or cream on the sides.1
- A dark cheek strip is the most distinct mark on the head.1
- It has a large rattle.1
Poder del veneno
El veneno sale por sus colmillos o dientes cuando muerde.
¿Qué hace su veneno?
Its venom contains a myotoxin, which damages muscle tissue and can cause muscle necrosis (death of muscle cells). It also contains a neurotoxin, which attacks the nerves and is similar to Mojave toxin. In recorded human bites, there was little local pain or swelling, and no significant whole-body (systemic) symptoms.1
¿Qué peligro tiene para las personas?
Peligro para las personas: GraveUna mordedura necesita médico. Las muertes son muy raras.Human bites by this snake are infrequent, and few cases have been recorded. Its venom is very toxic, but its low venom yield and short fangs probably prevent severe envenoming in adults. The clinical picture could be much more serious for children or for people of slight build.1
Buena noticia: los médicos tienen un medicamento (antídoto) o un tratamiento para esto.1
¿Qué hace cuando se asusta?
If disturbed, it rapidly shakes its rattle and may strike in defence, and it has an irascible (easily angered) temperament.1
Si muerde
- Early use of antivenom is important if significant envenoming is suspected. Get medical help straight away after any bite, even if the bite seems mild.1
- Mantén a la persona quieta y tranquila, la extremidad mordida a la altura del corazón, quítale anillos y cosas apretadas y llévala rápido a un hospital.

Mantente a salvo
- Nunca toques, atrapes ni molestes a un animal salvaje, aunque sea pequeño y aunque parezca dormido o muerto.
- Déjale espacio. Si te encuentras uno, mantén la calma, retrocede despacio y deja que siga su camino.
- Si te muerde: mantén la calma, no te muevas, llama a tu número de emergencias (112, 000, 911) o ve rápido a un hospital. Recuerda cómo era, una foto ayuda.

Datos
Its venom yield is small, but its toxicity is considered second highest of all rattlesnake venoms, after the Mojave rattlesnake.1
It has the smallest head of any rattlesnake, which helps it reach into small crevices to pull out prey that has crawled into them.1
Although it is a ground-dweller, it swims readily and has been found in bushes about 60 cm above the ground.1
Rattlesnake venom is used in biomedical research into neurological diseases.1
It is nocturnal during the hot summer, but becomes active during the day and at dusk in the autumn.1
Cazamitos
Mito: Its small head and short fangs mean its bite is harmless.
Verdad: Its venom is very toxic. Its small size and low venom yield probably prevent severe harm in adults, but children and slightly built people could be seriously affected.1
