一、栖息环境自然状态下的美国青蛙常栖息于江河、池塘、沼泽及岸边低洼多湿地带,尤其喜欢在水草或莲藕等植物繁茂、安静而阴凉的水域中,较少离水登陆,常常匍伏于水面的植物上。美国青蛙具有群居的习性,一般几只或几十只共栖一处,如栖息环境较稳定,一经适应,便不轻易迁移。夏天炎热时白天多钻入洞穴或浓密的草丛中,冬季寒冷时钻入较深的不冻土层或深水淤泥中御寒越冬。二、食性蛙类的生长发育过程要经历一个变态期,变态前和变态后的食性是不一样的。变态前蝌蚪以有机碎屑及浮游生物为食,变态后的幼蛙和成蛙则转变为动物食性。若在幼蛙期经人工驯养,也可直接吞食死饵或配合饲料。通常,美国青蛙喜欢捕食蚯蚓、蜗牛、昆虫、鱼 First, the habitat The natural state of the United States often inhabit rivers and lakes, ponds, marshes and low lying wetlands, especially like plants such as aquatic plants or lotus, lush and cool waters, less water landed, often creeping On the surface of the plants. American frogs have the habit of gregariousness, generally a few or dozens of only one habitat, such as the habitat of a more stable environment, once adapted, they do not easily migrate. When the summer is hot, it drills more caves or thick grass during the day and dries into the deep permafrost or the deep-water silt to keep the winter from freezing when the winter is cold. Second, the growth and development of dietary frogs to go through a metamorphosis, premorbid and metamorphosis diet is not the same. Pre-metamorphosis of tadpoles to organic debris and plankton for food, after the metamorphosis of the frog and into the frog is transformed into animal food. If by domesticated in the frog period, can also be directly swallowed dead bait or feed. Generally, American frogs like to prey on earthworms, snails, insects and fish
