The mamushi is a pit viper, a type of snake that has heat-sensing pits between its eyes and nostrils. It lives in Japan, in places such as swamps, meadows and farmland. It matters because its bite is one of the most dangerous of Japan's snakes.1

Leef in

Japan only. There is no evidence it occurs in the Ryukyu Islands.1

Asië

Tuis

It lives in swamps, marshes, meadows, open woodland, rocky hillsides and montane rock outcroppings. It is often found in and around farmland because rodents are common there.1

Lengte

45 cm tot 81 cm (1,5 ft tot 2,7 ft)1

Topspoed

omtrent 3,3 km/h (2,1 mph)

Op land, rowwe skatting

Wat eet dit?

It is an ambush predator. It waits hidden in vegetation or leaf litter, then eats mainly rodents, along with small birds, lizards and insects.1

Hoe om dit te herken

Background colour is pale grey, reddish-brown or yellow-brown.1
A series of irregular blotches runs along the body. Each blotch has a black border and often a lighter centre.1
The head is dark brown or black, with beige or pale-grey sides.1
Adults are typically 45 to 81 cm long.1
It has excellent camouflage and often hides among plants or leaf litter.1

Word dikwels verwar met: It is similar to the cottonmouths and copperheads (Agkistrodon) of the Americas, and it was long considered part of the same group.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 mostly haemolytic, meaning it breaks down red blood cells. It also contains two neurotoxins, which attack the nerves, and an anticoagulant, which stops blood from clotting. Reported effects include kidney failure, visual disturbances and palsy (paralysis).1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.

About 2000 to 3000 people in Japan are bitten by a mamushi each year. Approximately 10 die annually. Severe bites require intensive care, and typical bite victims need about one week of hospital treatment.1

Goeie nuus: dokters het 'n medisyne (teengif) of 'n behandeling hiervoor.1

As dit byt

Treatment is given in hospital. It involves cutting the wound to remove venom and injecting mamushi antivenom. Pregnant women who are bitten have had miscarriages, so medical care is essential.1
Hou die persoon stil en kalm, hou die gebyte arm of been op hartvlak, haal ringe en stywe goed af, en kom vinnig by 'n hospitaal uit.

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

Recovery takes a long time. Bite victims may need several months to fully recover, even after hospital treatment and weeks of follow-up care.1

It is highly resistant to its own venom because its blood contains neutralising factors, including phospholipase A2 (PLA2) inhibitors.1

Its beta-toxin acts before the nerve junction, so anticholinesterase drugs cannot block or treat its effects.1

Its venom contains a peptide called ablomin, which is very similar in amino acid sequence to helothermine, a venom peptide of the Mexican beaded lizard.1

It is considered one of the most venomous snakes in Japan, along with the yamakagashi and the Okinawan habu.1

Its venom varies very little across Japan in either potency or effects.1
