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

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

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

Habari njema: madaktari wana dawa (ya kuzuia sumu) au matibabu ya hili.1

Hufanya nini akiogopa?

It relies on camouflage and will often stay still rather than strike or rattle unless it is physically harassed.1

Akiuma

Mweke mtu bila kutikisika na mtulivu, weka kiungo kilichoumwa usawa wa moyo, ondoa pete na vitu vinavyobana, na umpeleke hospitali haraka.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

inafaa kujua

Ukweli

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

Kuvunja dhana potofu

Dhana potofu: You can tell a rock rattlesnake's age by counting the segments on its rattle.

Ukweli: 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
