The In­va­sive Chan­neled Ap­ple Snail

China Scenic - - Wildlife -

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.
