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

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

Zer egiten du bere pozoiak?

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

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

Zer egiten du beldurtzen denean?

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

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.

Datuak

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

Mito-hauslea

Mitoa: Its bite is deadly to people.

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