The sidewinder is a small rattlesnake that lives in the deserts of the south-western United States and north-western Mexico. It gets its name from the unusual sideways way it moves over loose sand. It is venomous, but its venom is weaker than that of many other rattlesnakes.1

Leef in

Desert regions of south-eastern California, southern Nevada, south-western Utah, western Arizona, western Sonora and eastern Baja California1

Noord-Amerika

Tuis

It lives in desert regions, where it often lies almost buried in sand. It also uses small rodent burrows, both as shelter and as a place to give birth.1

Lengte

43 cm tot 80 cm (1,4 ft tot 2,6 ft)1

Topspoed

omtrent 29 km/h (18 mph)

Op land: dikwels berigte topspoed van 'n sywinder-ratelslang

Wat eet dit?

Adults eat desert rodents, birds and other snakes. Juveniles wave their tails to attract lizards, which they then catch.1

Hoe om dit te herken

Small, measuring 43 to 80 cm in total length including the tail.1
Raised scales above the eyes give it horns.1
The ground colour may be cream, buff, yellowish-brown, pink or ash grey, with 28 to 47 darker blotches along the back.1
It moves with a sidewinding motion, leaving a J-shaped track in the sand with the tip of the hook pointing in the direction of travel.1
Females are larger than males, which is unusual among United States rattlesnakes.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

The venom causes pain, swelling and bruising, and can create bleeding blisters. Symptoms can include nausea, dizziness, chills, blood clotting disorders and shock. In one recorded case, a bitten man's whole arm was badly swollen and very painful within about 2.5 hours.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Ernstig'n Byt moet deur 'n dokter gesien word. Sterftes is baie skaars.

Its venom is weaker than that of many other rattlesnakes, and its venom glands are smaller, so it is less dangerous than its larger relatives. Any rattlesnake bite can still be fatal and should be taken seriously.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

As dit byt

Seek medical attention immediately after any rattlesnake bite. Consult a local expert or regional poison control centre before giving antivenom.1
Hou die persoon stil en kalm, hou die gebyte arm of been op hartvlak, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

The AIM-9 Sidewinder missile was named after this snake, because both use infrared signals to track their targets.1

Juveniles and adults use different hunting methods. Juveniles lure lizards with fast tail movements that look like a moth or slower ones that look like a caterpillar.1

The raised scales above its eyes may shade the eyes or stop sand drifting over them. When the snake strikes against a burrow roof, pressure on these horns folds them down, which is thought to protect the eyes.1

Newborn sidewinders huddle together in a burrow for their first week or so, plugging the entrance during the day. Their combined body heat keeps the group at an average of about 32 °C, which is warm enough for shedding.1

Sidewinding is also used by other desert snakes, such as the horned adder and Peringuey's adder, and by robots that copy this movement.1
