Caspian cobra
BidThe Caspian cobra is a highly venomous snake that lives in Central Asia, Afghanistan, Iran and Pakistan. Many scientists consider it the most venomous cobra in the world. It is also a strong swimmer and a good climber.1
Sådan genkender du det
- Adults are light to chocolate brown or yellowish, with no hood marks and no spots on the throat.1
- Juveniles are pale and faded, with dark and light cross-bands of about equal width around the body.1
- The hood is long and tapers gradually, unlike the rounder hood of some other cobras.1
- It has several dark bands under the throat.1
- It is never fully black, although some individuals can be quite dark.1
Forveksles ofte med: The Caspian cobra is often confused with the Indian cobra, and the two live side by side in Pakistan and northern India. Indian cobras without a hood mark look similar. In the black form of the Indian cobra from Pakistan, almost the whole throat is black, while the Caspian cobra has several dark throat bands and is never fully black.1
Giftkraft
Giften kommer ud gennem gifttænderne eller tænderne, når det bider.
Hvad gør dets gift, når det bider eller stikker?
Its venom is mainly neurotoxic, meaning it attacks the nerves, and most of the venom is made of short neurotoxins. It also contains cytotoxins, which can kill cells, and enzymes called nucleases, which damage tissue at the bite. Severe pain and swelling appear quickly, and weakness, drowsiness and paralysis of the throat and limbs can appear within an hour. The venom can also affect the heart during the first few hours, and at least one heart attack after a bite has been recorded.1
Hvor farligt er det for mennesker?
Fare for mennesker: DødeligEt af de farligste dyr i verden.It is regarded as the most dangerous snake in Central Asia and has a high death rate. Between 1979 and 1987, 136 confirmed bites were attributed to it in the former Soviet Union. Of these, 8 people died after receiving antivenom, and 11 of the 15 who did not receive antivenom died. In Iran, it causes more deaths from snakebite than any other snake in the country. Without treatment, death can come in as little as 45 minutes or be delayed for up to 24 hours.1
Gode nyheder: Lægerne har en medicin (modgift) eller en behandling mod det.1
Hvad gør det, når det er bange?
It tends to avoid people, but when cornered or provoked it spreads its hood, hisses, sways from side to side and strikes repeatedly.1
Hvis det bider
- Medical treatment with antivenom is essential, because untreated bites are often fatal. Symptoms can worsen rapidly without treatment, so urgent medical care is needed.1
- Hold personen i ro og rolig, tag ringe og stramme ting af, og kom hurtigt på hospitalet: Modgift (antiserum) er behandlingen.

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
Many toxinological studies suggest that the Caspian cobra is the most venomous cobra in the world.1
A ribonuclease called ribonuclease V1, purified from its venom, is used as a laboratory reagent in molecular biology because it can break down structured RNA.1
It cannot spit venom, but it is a good climber and an able swimmer.1
It is the westernmost species of Asiatic cobra, and it can be found at heights of up to about 3,000 m.1
For most of the twentieth century it was treated as a subspecies of the Indian cobra, until genetic analysis showed it was a separate species.1
