Rock rattlesnake
The rock rattlesnake is a small rattlesnake that lives in the south-western United States and northern central Mexico. It spends most of its life among rocks and hides well by blending in with its surroundings. It is venomous, so it is important to know what it looks like and to give it plenty of room.1

Poder del verí
El verí surt pels ullals o les dents quan mossega.
Què fa el seu verí?
Its venom is mainly a hemotoxin, a type of venom that acts on the blood and body tissues. It can also have significant neurotoxic effects, which attack the nerves.1
Com de perillós és per a les persones?
Perill per a les persones: GreuUna mossegada necessita un metge. Les morts són molt rares.The snake is not aggressive and relies on camouflage, so it often will not strike or rattle unless it is harassed. However, if someone steps on it or touches it by accident, its immediate reaction is to bite. Most people bitten by this snake were hiking among rocks.1
Bona notícia: els metges tenen un medicament (l'antiverí) o un tractament per a això.1
Què fa quan té por?
It relies on camouflage and will often stay still rather than strike or rattle unless it is physically harassed.1
Si mossega
- 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.
No va a per tu. Fa servir el verí per caçar o per defensar-se, i prefereix mil vegades amagar-se. Més sobre com estar segur

Dades
A new segment is added to the rattle each time the snake sheds its skin, but the rattle can break off, so segments do not give a reliable age.1
Its rattle is made of keratin, the same material as human fingernails.1
Its colour generally reflects the colour of the rock where it lives, which helps it stay hidden.1
The young take three or more years to mature.1
Desmuntamites
Mite: You can tell a rock rattlesnake's age by counting the segments on its rattle.
Veritat: A segment is added each time the snake sheds, but the rattle is fragile and can break off, and shedding frequency varies. So the number of segments cannot tell you its age.1
