The American toad is a common toad found across the eastern half of Canada and the United States. It lives in forests, grasslands and gardens, and it breeds in shallow ponds and pools. It matters because it eats many insects and other small creatures, and its skin releases a substance that can irritate eyes and harm small animals such as dogs.1

Strupena ob ugrizu ali ob dotiku? Nekatere živali strup vbrizgajo z ugrizom ali pikom: te so strupene ob ugrizu ali piku. Druge so škodljive, če se jih dotakneš ali jih poješ: te so strupene za dotik ali zaužitje. Ta žival je strupena za dotik ali zaužitje.

Domov
American toads need a semi-permanent freshwater pond or pool with shallow water for breeding, and dense patches of vegetation for cover and hunting. They can live almost anywhere with these features, from forests to flat grassland. They often shelter in burrows, under boards, flat stones, logs, woodpiles and window wells.1

Kako jo prepoznaš

  • Adults are usually 5 to 9 cm long.1
  • Skin colour varies from yellow to brown to black, and can be solid or speckled. It changes with habitat colours, humidity, stress and temperature.1
  • Spots on the back contain only one or two warts, and the lower legs have enlarged warts.1
  • The parotoid glands are the same colour as the surrounding skin.1
  • Breeding males give a high trill lasting 6 to 30 seconds that sounds like a ringing telephone.1

Pogosto zamenjujejo z: Fowler's toad, Woodhouse's toad, the Canadian toad, the southern toad and the Gulf Coast toad can look similar. Fowler's toad never has a spotted belly, and its cranial crests touch the parotoid glands. The American toad's crests almost never touch the glands. The Canadian toad's crests join to form a raised bump, which the American toad's do not. The southern toad's crests form two distinct knobs.1

Moč strupa

Strup v koži

Njena koža je strupena. Nevarno se je je dotakniti, jo polizati ali pojesti.

Kaj naredi njen strup, če se je dotakneš ali jo poješ?

The American toad does not inject venom. Its parotoid glands secrete bufotoxin, a poisonous substance that makes the toad unpalatable to predators. It is a mild poison compared with other poisonous toads and frogs, but it can irritate human eyes and mucous membranes and is dangerous to smaller animals such as dogs when swallowed.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: BlagaKot čebelji pik ali manj. Za ljudi praktično neškodljiva.

Bufotoxin is a mild poison. It can irritate human eyes and mucous membranes, and it is dangerous to smaller animals, such as dogs, if they swallow it.1

Kaj naredi, ko se prestraši?

When threatened, the toad releases bufotoxin from its parotoid glands, which makes it unpleasant to eat.1

Če se je je kdo dotaknil ali jo pojedel

  • Če se je je kdo dotaknil: dobro umij roke in se ne dotikaj oči ali ust. Če jo je otrok ali hišni ljubljenček polizal ali pojedel: pokliči center za zastrupitve ali številko za klic v sili.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

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 si se je dotaknil ali jo pojedel: ne drgni si oči ali ust, umij si roke in poišči zdravniško pomoč.

Ne preži nate. Njen strup je tam samo zato, da je nihče ne poje. Več o varnosti

Dejstva

1

Some American toads have lived for over 30 years, and one female was reported to be living healthily into her late 30s.1

2

Toads avoid mating with their siblings. Males' calls seem to help females recognise their close relatives.1

3

Toad tadpoles produce toxic chemicals in their skin that discourage some predators. Most fish learn quickly to avoid eating them.1

4

Their skin colour can change with their surroundings, humidity, stress and temperature.1

5

Tadpoles swim in very shallow water, often among thick grass, and gather in schools during the day to reduce predation.1

6

Toadlets often leave the water together in large groups and migrate to shaded forest areas near where they were bred.1
