Toads have larger lumps behind their eyes. The bumps and lumps are glands. The glands produce a whitish goo that is a foul-tasting and smelly poison. The poison is a toad’s ultimate defense in a predator attack. It is toxic enough to kill small animals, if they swallow enough of it. The toxin can cause skin and eye irritation in humans. Some people used to think toad warts were contagious傳染性的. Touching a toad can’t cause human warts, but licking a toad might make you sick! Parts of frog Life cycle of toadToads breed in water. In springtime male and female toads gather in large numbers around ponds, marshes, and ditches. 蟾蜍在水中繁殖。在春季，雌性蟾蜍大量聚集在池塘，沼澤和溝渠周圍。In the sexual embrace, called amplexus, the male toad clasps the female from behind. The pair swims about as the female, swollen with eggs, selects a site for depositing them. 雄性蟾蜍從后面抱住雌性，雌性選擇一個放置排放卵。As several thousand eggs are expelled from the female's body in jelly-like strings, the male fertilizes them with sperm. 當(dāng)成果凍形卵從雌性體內(nèi)排出時，雄性就通過精子使卵受精。The jelly surrounding the eggs swells in the water until each egg is covered with a thick coating. This acts as a float to keep the eggs near the surface of the water, where it is warmer and there is more oxygen. 卵周圍的果凍狀在水中膨脹，直到每個卵都被厚涂層覆蓋。它起著漂浮的作用，使卵保持在水面附近，那里的水比較溫暖，并且有更多的氧氣。In a few days a tadpole will hatch from each fertilized egg. 再過幾天，蝌蚪就會從每個受精卵中孵出。First, the developing tadpole grows longer. 首先，蝌蚪不斷增長。Then, the body and tail take shape, and the tadpole shows signs of life with small wriggling movements. At this stage the tadpole does not have any legs and breathes through gills. 然后，身體和尾巴就成型了，蝌蚪以微小的蠕動動作顯示了生命跡象。在此階段，他沒有腿，通過腮呼吸。In the next stage of development, the tadpole loses the gills and develops lungs.在隨后的日子里，蝌蚪會失去腮，而會發(fā)展成肺。Finally, limbs appear—first two hind legs and then two front legs—and the tail is absorbed. 最后，出現(xiàn)四肢-先是兩條后腿，然后是兩條前腿-并吸收尾巴。The tadpole has metamorphosed into a toad, able to climb out of the water and begin a new way of life on land. 蝌蚪變成了蟾蜍，可以爬出水面，開始在陸地上生活。 區(qū)別在于toad lays eggs in a chain, 而frog lays eggs in clusters(團(tuán)). Frog cut and paste What do Toads Eat?Since baby toads, that are called tadpoles, live in pools and watery lands, they like to have algae and other things found in water as their diet. Whereas the adult toads like to have insects (beetles, ants, crickets, butterflies, grasshoppers), worms, spiders, snails and other mites in their diet. Like frogs, toads also grasp their prey with the help of their long tongues. The interesting thing is that toad doesn't chew its prey and gulp it as a whole. As per research facts, an American toad can easily eat one thousand preys at maximum, in a day. Differences Between a Frog and a Toad ?青蛙和癩蛤蟆的區(qū)別 后腿的區(qū)別：Frog后腿長，多跳躍；Toad后腿短，多爬行。 腳趾區(qū)別：frog擁有蹼足，可能還有粘性的墊子，大多時間生活在水中；toad腳趾分開，腳掌無墊。 身體形狀：frog在外形上苗條，四肢較長；toad又矮又粗，腿較短。 皮膚：frog皮比toad皮膚光滑得多，toad上有小突起。 看顏色：通常，frog的顏色比toad的顏色淺。但不能完全依賴只看顏色，因?yàn)橐灿凶厣那嗤堋?需要參考其他因素。 跳躍：frog跳得很高，而且跳得也很長。toad跳很短，缺乏跳遠(yuǎn)的能力。 爬行：toad更喜歡爬行，而frog不會。 水源：frog需要靠近水才能生存，而蟾蜍可能會在陸地上花費(fèi)大量時間。 Color a toad and a frog1. Color or paint and decorate one coloring to resemble a frog and a toad. Choose a light color for frog and a dark color for toad.2. For the frog image, sprinkle a few drops of water to the paint to make a smooth moist texture.4. Glue some green beans to make the surface appear bumpy and warty.5. Glue some kidney beans to make dark spots on the toad surface.Toads: they are all fat and round and have short legs and dry, warty skin. They are generally mottled brown or gray, often with dark spots.Frogs: Their skin is smooth and moist. They are in a variety of colors, from brown, red, green, and other colors, and with stripes or dark spots.
