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

Domov

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

Kaj je?

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

Kako jo prepoznaš

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

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

Kako nevarna je za ljudi?

Nevarnost za ljudi: BolečeLahko zelo boli, a skoraj nikoli ni resno.

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

Kaj naredi, ko se prestraši?

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

Če ugrizne

Poškodovanca drži pri miru in ga pomirjaj, ugriznjeni ud drži v višini srca, odstrani prstane in tesne stvari ter ga hitro odpelji v bolnišnico.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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

Razbijalec mitov

Mit: Its bite is deadly to people.

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