The eastern hognose snake is a stout, rear-fanged snake that lives across eastern and central North America. It has an upturned snout, which it uses for digging in sandy soil. It is mildly venomous, but its venom is aimed at toads and frogs and is not deadly to people.1

Giftkraft

Bid

Giften kommer ud gennem gifttænderne eller tænderne, når det bider.

Hvad gør dets gift, når det bider eller stikker?

Its venom is mild and is adapted to amphibian prey. It is delivered through enlarged rear teeth from the Duvernoy's gland. In people who are allergic to the snake's saliva, a bite can cause local swelling, burning, discolouration and bleeding from the wound.1

Hvor farligt er det for mennesker?

Fare for mennesker: MildSom et bistik eller mindre. Stort set harmløst for mennesker.

The venom is harmless to most people, and no human deaths have been documented. People who are allergic to its saliva may have local symptoms such as swelling and bleeding.1

Hvad gør det, når det er bange?

It flattens its neck, raises its head like a cobra, hisses and strikes with a closed mouth to bluff. If that fails, it rolls onto its back, plays dead, releases a foul musk and lets its tongue hang out.1

Hvis det bider

Vask biddet, hold personen rolig, og få lægehjælp. Nogle arter (som boomslangen) kan være dødelige flere timer senere.

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

One individual was seen playing dead for 45 minutes before moving away.1

It is resistant to the skin poisons of toads, probably because of its enlarged adrenal glands, which release large amounts of hormones to counter the toxins.1

When threatened, it often bluffs by striking with its mouth closed, and it does not try to bite.1

It is a rear-fanged snake, and its enlarged teeth are at the back of the upper jaw.1

Females can store sperm until spring, so they can be fertilised later.1
