The eastern coral snake is a highly venomous snake with bright rings of red, yellow and black. It lives in the southeastern United States, including all of Florida. Its bright colours warn predators to keep away, and it is one of the snakes that people most need to recognise.1

Domov

It lives in upland hammocks, scrub, pine flatwoods and dry, open, bushy ground, often on sandy soil. Coral snakes spend most of their time underground or sheltering under objects, so people rarely see them.1

Kaj je?

It eats mainly other snakes and lizards, and also eats mammals, birds, frogs, fish and insects. It bites the head of its prey first to inject venom, then holds on until the prey is paralysed before swallowing it.1

Kako jo prepoznaš

Wide red and black rings are separated by narrow yellow rings all along the body.1
The head is black from the snout to just behind the eyes, with a yellow band behind the eyes.1
The red rings are usually speckled with black.1
Adults are usually less than 80 cm long, including the tail.1

Pogosto zamenjujejo z: The scarlet snake and the scarlet kingsnake are nonvenomous mimics with similar colours. Kingsnakes and the scarlet snake are helpful predators of rats and mice, so the difference matters.1

The venom is a potent neurotoxin, which attacks the nerves. In humans, symptoms can include local pain, slurred speech, double vision, weakness and paralysis, and in severe cases breathing can fail. An estimated 5 mg of venom can be lethal to humans.1

Bites and deaths are very rare. Two deaths were documented in the 1950s, and one more has been reported since antivenin became available in the 1960s, the most recent in 2006. The snake is secretive and reluctant to bite; an estimated 40% of bites inject venom, though a 1987 study found 75%.1

Dobra novica: zdravniki imajo za to zdravilo (protistrup) ali zdravljenje.1

Kaj naredi, ko se prestraši?

When threatened it tries to escape, and if it cannot, it may hide its head under its coils, mimic the head with its tail, move erratically or feign death.1

Če ugrizne

The most recent victim died after failing to seek proper medical attention, so anyone bitten should get medical help straight away. Antivenom is available.1
Poškodovanca drži pri miru in ga pomirjaj ter ga hitro odpelji v bolnišnico, tudi če je ugriz videti majhen: simptomi se lahko začnejo šele čez nekaj ur.

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.

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

vredno vedeti

Dejstva

An adult's venom can kill up to five adult humans, but the snake cannot release all of it in a single bite.1

Unlike New World pit vipers, the coral snake cannot control how much venom it injects.1

Males mature 11 to 16 months after hatching, while females take about 26 months.1

Coral snakes are mostly active during the day, and night sightings are rare.1

The range could expand up to 200 km northward because of climate change, according to future models.1

Razbijalec mitov

Mit: "Red and yellow, kill a fellow" is a reliable way to tell a venomous coral snake from a harmless mimic.

Resnica: The rhyme is a folk saying that only applies to snakes in the southern United States, and it does not work anywhere else.1
