American toad
Gif in sy velEet: InsekteGiftig om aan te raak of te eet, nie deur 'n byt of steek nieThe 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
Hoe om dit te herken
- 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
Word dikwels verwar met: 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
Gifkrag
Sy vel is giftig. Dit is gevaarlik om aan te raak, te lek of te eet.
Wat doen sy gif as jy daaraan raak of dit eet?
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
Hoe gevaarlik is dit vir mense?
Gevaar vir mense: LigSoos 'n bysteek of minder. Basies onskadelik vir mense.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
Wat doen dit as dit bang is?
When threatened, the toad releases bufotoxin from its parotoid glands, which makes it unpleasant to eat.1
As iemand daaraan geraak of dit geëet het
- As iemand aan een geraak het: was die hande goed en moenie aan die oë of mond raak nie. As 'n kind of troeteldier een gelek of geëet het: bel 'n gifsentrum of jou noodnommer.
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 jy daaraan geraak of dit geëet het: moenie jou oë of mond vryf nie, was jou hande en kry mediese hulp.
Dit is nie uit om jou te kry nie. Sy gif is net daar sodat niks dit eet nie. Meer oor veilig bly

Feite
Some American toads have lived for over 30 years, and one female was reported to be living healthily into her late 30s.1
Toads avoid mating with their siblings. Males' calls seem to help females recognise their close relatives.1
Toad tadpoles produce toxic chemicals in their skin that discourage some predators. Most fish learn quickly to avoid eating them.1
Their skin colour can change with their surroundings, humidity, stress and temperature.1
Tadpoles swim in very shallow water, often among thick grass, and gather in schools during the day to reduce predation.1
Toadlets often leave the water together in large groups and migrate to shaded forest areas near where they were bred.1
