Eastern green mamba
BidThe eastern green mamba is a highly venomous snake with a slender body and bright green back. It lives in trees along the coasts of southern and East Africa. Although it is one of the most common green mambas, it is shy and usually hidden in leaves, so it is rarely seen.1
Sådan genkender du det
- Bright green upperparts, sometimes with a few isolated yellow scales.1
- Pale yellow-green belly.1
- Juveniles are blue-green and turn bright green at about 75 cm long.1
- Long, slender, coffin-shaped head. It can flatten its neck into a slight hood when threatened.1
- The inside of the mouth is white or bluish-white.1
Forveksles ofte med: Green forms of the boomslang are often called green mambas in Southern Africa. They have larger eyes and shorter heads. Green bush snakes of the genus Philothamnus are often confused with smaller eastern green mambas. The boomslang is also venomous.1
Giftkraft
Giften kommer ud gennem gifttænderne eller tænderne, når det bider.
Hvad gør dets gift, når det bider eller stikker?
Its venom contains neurotoxins, which attack the nerves, and cardiotoxins, which damage the heart. Symptoms include swelling at the bite, dizziness, nausea, dehydration, laboured breathing and difficulty swallowing. These can progress to irregular heartbeat, convulsions and respiratory paralysis, which stops breathing and can be fatal. Paralysis may be mild or absent.1
Hvor farligt er det for mennesker?
Fare for mennesker: DødeligEt af de farligste dyr i verden.A survey in southern Africa from 1957 to 1979 recorded 17 bites confirmed as eastern green mambas. Ten of these caused systemic envenomation, and no victims died. Bites are most common from September to February, the breeding season, when the snake is most irritable. The average dose able to kill a human is about 18 to 20 mg of venom, and one bite can deliver 60 to 95 mg (dry weight). In 2024, a YouTuber died after being bitten, following anaphylactic shock.1
Hvad gør det, når det er bange?
It is shy and avoids people and predators, attacking only when it feels threatened, and it can flatten its neck into a hood.1
Hvis det bider
- Severe bites must be treated immediately on site, as they can quickly prove deadly.1
- Hold personen i ro og rolig, tag ringe og stramme ting af, og kom hurtigt på hospitalet: Modgift (antiserum) er behandlingen.
Ring altid først til dit alarmnummer (112, 000, 911). Dette er generel førstehjælpsvejledning, ikke lægelig rådgivning. Grundlæggende førstehjælp
Pas på dig selv
- Rør aldrig ved, fang eller dril et vildt dyr, heller ikke et lille et, og heller ikke hvis det ser ud til at sove eller være dødt.
- Giv det plads. Hvis du møder et, så bliv rolig, træd langsomt tilbage, og lad det gå sin egen vej.
- Hvis et bider dig: Bevar roen, hold dig i ro, ring til dit alarmnummer (112, 000, 911), eller kom hurtigt på hospitalet. Husk, hvordan det så ud, et billede hjælper.
Det er ikke ude efter dig. Det bruger sin gift til at fange føde eller beskytte sig selv, og det gemmer sig meget hellere. Mere om sikkerhed

Fakta
Males fight each other during the breeding season, usually entwining and pushing to pin each other's heads down. These fights can last several hours, but the snakes do not bite each other.1
Unlike most elapid snakes, which hunt actively, it often waits in ambush for its prey, a style more common among vipers.1
On average, an individual moves only about 5.4 metres per day, and it can stay in the same place for days.1
It has the least toxic venom of the three green mamba species, but it is still highly venomous.1
The oldest recorded eastern green mamba was a captive snake that lived 18.8 years.1
Myteknuser
