Before 1935, there were no cane toads in Australia. Today, they are a huge presence in the country. In fact, scientists estimate that there are 83 toads for every person there! The big amphibians--which can weigh close to three pounds--show up on highways, in watering holes meant for cattle, and in people's yards in town. Because they ooze a powerful poison when attacked, they kill many wild animals as well as pets each year. In Australia's Cane Toads: Overrun, students will learn all about these troublesome creatures. The fascinating account describes why and how the toads were first brought to Australia, how they spread far and wide, and what scientists and everyday people are doing to try to control their population today. Large color photos, maps, and fact boxes enrich the dramatic details. Written in narrative format, this series is sure to keep young readers engaged.
