The Mexican beaded lizard is a venomous lizard found mainly in Mexico and southern Guatemala. It is one of only a few lizards known to have evolved a true venom delivery system. Its venom is also being studied for possible medicines.1

Mexico, from Sonora to Oaxaca, and parts of southern Guatemala (the Pacific and Atlantic drainages).1

Noord-Amerika

Lengte

57 cm tot 91 cm (1,9 ft tot 3 ft)1

Hoe om dit te herken

Black with yellowish spots or bands.1
Small, beadlike scales that do not overlap, which give it its name.1
Stocky body with a broad head.1
Short tail that stores fat, and does not regrow if broken.1
Adults are 57 to 91 cm long.1

Word dikwels verwar met: The Gila monster is its closest relative and looks similar. The Mexican beaded lizard is larger, and its colours are duller, black with yellowish bands.1

Gifkrag

Byte

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

Wat doen sy gif as dit byt of steek?

Its venom is a weak hemotoxin, meaning it attacks blood and tissue. It can cause respiratory failure, which is when breathing fails. In humans, bites cause severe pain that can spread well beyond the bite and last up to 24 hours, along with swelling, weakness, sweating and a rapid drop in blood pressure.1

Hoe gevaarlik is dit vir mense?

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

Human deaths from its bites are rare. Eight human bites were documented in the past century, and almost all happened when people prodded captive lizards with a finger or bare foot.1

As dit byt

Was die wond, hou die persoon kalm en kry mediese hulp.

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

It is one of only two venomous beaded lizard species, and the only lizards known to have evolved an overt venom delivery system, along with the rest of its genus.1

Some compounds in its venom are being studied for possible treatments of diabetes, Alzheimer's disease and HIV. One of them, exendin-3, is the basis of the drug exenatide.1

The beaded lizard is immune to the effects of its own venom.1

It is larger than the Gila monster, with an average adult weight of 800 g, and large specimens exceed 2,000 g.1

Beaded lizards have forked pink tongues that they use to smell, with the help of a Jacobson's organ.1

Young beaded lizards are rarely seen, as they are believed to spend much of their early lives underground.1

Mite-breker

Mite: The beaded lizard is more venomous than a rattlesnake, can cause lightning strikes with its tail, or can make a pregnant woman miscarry by looking at her.

Waarheid: These beliefs are incorrect. Its venom is weak, and human deaths are rare.1
