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

Anadunga sumu au ana sumu ya kugusa? Wanyama wanaodunga sumu huingiza sumu kwa kuuma au kudunga. Wanyama wenye sumu ya kugusa au kula hudhuru wakiguswa au kuliwa. Huyu ni wa aina ya pili.

Nyumbani

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

Jinsi ya kumtambua

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

Mara nyingi huchanganywa na: 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

Nguvu ya sumu

Sumu ndani ya ngozi

Ngozi yake ina sumu. Ni hatari kumgusa, kumramba au kumla.

Sumu yake hufanya nini?

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

Hatari kwa watu: HafifuKama kudungwa na nyuki au chini ya hapo. Kimsingi hana madhara kwa watu.

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

Hufanya nini akiogopa?

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

Mtu akimgusa au kumla

Mtu akimgusa: nawa mikono vizuri na usiguse macho wala mdomo. Mtoto au mnyama kipenzi akimramba au kumla: piga kituo cha taarifa za sumu au namba ya dharura.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Ukimgusa au kumla: usisugue macho wala mdomo, nawa mikono na utafute msaada wa kitabibu.

Hakuwindi wewe. Sumu yake ipo tu ili asiliwe na yeyote. Zaidi kuhusu kukaa salama

Ukweli

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
