According to this story from the News & Observer, North Carolina is taking the discovery of giant African land snails (Achatina fulica) in Wisconsin very seriously. Officials are concerned that teachers in their own state may have used the snails in classroom projects, and could be releasing them into the wild now that school is out. Read about the Wisconsin snails in this old ISW post. Bonus points to the News & Observer for using scientific names.
