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

물거나 쏘는 독일까, 만지거나 먹으면 독일까? ‘물거나 쏘는 독’을 가진 동물은 물거나 쏴서 독을 주입해. ‘만지거나 먹으면 독’인 동물은 만지거나 먹으면 해로워. 이 동물은 ‘만지거나 먹으면 독’이야.

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

알아보는 법

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

자주 헷갈리는 동물: 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

독의 힘

피부에 독

피부에 독이 있어. 만지거나, 핥거나, 먹으면 위험해.

이 독(만지거나 먹으면 독)은 어떤 작용을 할까?

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

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

무서울 때 어떻게 할까?

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

누가 만지거나 먹었다면

누가 그걸 만졌다면: 손을 잘 씻고 눈이나 입을 만지지 마. 아이나 반려동물이 핥거나 먹었다면: 중독 센터나 응급 번호에 전화해.

안전하게 지내

야생 동물은 작더라도, 자거나 죽은 것처럼 보이더라도 절대 만지거나, 잡거나, 괴롭히지 마.
거리를 둬. 마주치면 침착하게 천천히 뒤로 물러나서 제 갈 길을 가게 해 줘.
만지거나 먹었다면: 눈이나 입을 비비지 말고, 손을 씻고, 의료 도움을 받아.

사실

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
