The Invasive Channeled Apple Snail
Native to South America, the channeled apple snail is a kind of large freshwater snail well-known as an invasive species that can do great harm to agriculture. It was first introduced to China during the 1980s as an edible snail. Later it was not so popular among consumers and so was released into the fields. During breeding season, their conspicuous pink eggs fill farmland ditches. Currently, controlling apple snails is a challenge to farmers and scientists in China. Fortunately, the newly-arrived Asian openbills are natural predators of these annoying creatures.
