The pygmy rattlesnake is a small, venomous snake that lives in the southeastern United States. It is the smallest rattlesnake found on the North American continent. Its venom is strongly tissue-damaging, but the snake makes so little that a bite is unlikely to be fatal to an adult.1

Leef in

Southeastern United States, from southern and eastern North Carolina south through peninsular Florida and west to East Texas and Oklahoma1

Noord-Amerika

Tuis

It lives in flatwoods, sandhills, longleaf pine savannahs, mixed scrub oak forests and floodplains, and is also found near lakes and marshes. It does not dig its own burrows. It uses holes dug by small rodents or gopher tortoises, and it prefers densely vegetated areas for cover.1

Lengte

40 cm tot 79 cm (1,3 ft tot 2,6 ft)1

Topspoed

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

Op land, rowwe skatting

Wat eet dit?

It eats small mammals, birds, lizards, insects, frogs and other snakes, and also giant desert centipedes. Young snakes lure skinks by waving the tail, while adults wait motionless in a coil for days at a time.1

Hoe om dit te herken

Small but bulky in width, usually 40 to 60 cm long including the tail1
Dorsal pattern of oval or roughly circular spots with somewhat regular edges1
Flank spots are mostly round and not much taller than they are wide1
Usually 23 rows of dorsal scales at midbody1
Young snakes may be paler or more vividly marked, and have a yellow tail tip. The rattle is tiny and gives only a faint buzz that is heard from a few feet away1

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 cytotoxic, which means it damages cells, and it is strongly haemorrhagic, which means it causes bleeding. The venom is tissue-toxic but contains no neurotoxins, which attack the nerves. The snake produces only a small amount of venom and contains substantial amounts of serotonin and related compounds.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

The snake produces too little venom to be likely to deliver a fatal bite to a human adult.1

Wat doen dit as dit bang is?

Some individuals are very aggressive and strike furiously, while others are lethargic and do not rattle at all, and many are reluctant to bite.1

As dit byt

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

Its venom was the basis for the drug eptifibatide, which is used to prevent clotting during a heart attack.1

It is the smallest rattlesnake found on the North American continent.1

Its rattle is unusually small, which may show the early stages of how rattles evolved.1

Snake fungal disease has risen sharply in pygmy rattlesnakes over the past decade and is a major cause of death, though some snakes have recovered in the field.1

Females may give birth to live young even while infected with snake fungal disease.1

Mite-breker

Mite: Its bite is deadly to people.

Waarheid: The snake makes so little venom that a bite is unlikely to be fatal to an adult human.1
