Lichtenstein's green racer is a long, green snake with a rear-fanged bite. It lives in parts of southern South America, including northern Argentina, Brazil, Bolivia and northwestern Paraguay. It is venomous, and its bite can cause serious harm, so it is worth knowing what it looks like.1

Tuis

It lives in many habitat types, including the Cerrado, Caatinga, forest, forest transition and restinga. It has been found from sea level up to 1,700 m (5,600 ft). It is often arboreal, meaning it spends much of its time in trees, but it also hunts on the ground.1

Lengte

1 m tot 1,5 m (3,3 ft tot 4,9 ft)1

Topspoed

omtrent 5,5 km/h (3,4 mph)

Op land, rowwe skatting

Wat eet dit?

It eats small rodents, lizards, amphibians and birds, especially nestlings. It will also eat other snakes, including some almost as large as itself.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 highly haemorrhagic, which means it causes bleeding, and it also breaks down fibrinogen, a protein needed for clotting. It also contains neurotoxic components that affect the nerves, and it is myotoxic, meaning it damages muscle. Common symptoms are pain, swelling, redness and bruising, and bruising can spread far from the bite, even up the arm or to the chest and abdomen.1

Hoe gevaarlik is dit vir mense?

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

Accidents are generally not serious, because the snake has difficulty injecting venom and produces only small amounts. However, there have been reports of serious bites needing medical treatment. In one recent severe case, the snake was allowed to bite for a long time, and the victim developed clotting problems, liver damage and severe swelling. Only one death has been reported, and it was a child.1

As dit byt

Serious bites need medical treatment. The antivenom made for Bothrops snakes is not suitable for bites from this snake.1
Was die byt, hou die persoon kalm en kry mediese hulp. Sommige spesies (soos die boomslang) kan ure later dodelik wees.

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

die moeite werd om te weet

Feite

In laboratory mice, its venom had a lethality equivalent to that of Bothrops asper, a pit viper.1

It is rear-fanged, so its fangs are at the back of the mouth, and it chews venom into its prey through a grooved tooth.1

The venom is made in the Duvernoy's gland at the back of the mouth, and the snake must work hard to deliver it.1

Mite-breker

Mite: Bites from this snake are never serious.

Waarheid: Most accidents are not serious, because the snake struggles to inject venom. Still, serious bites have happened, and one child has died, so any bite needs medical attention.1
