TALLAHASSEE, Fla. – Florida is known for fighting invasive species. The state encourages people to kill lionfish, iguanas and pythons. But now there’s a new non-native critter to worry about -- the horntail snail. The gastropod that’s a pest in India for its voracious consumption of farm products was found in Miami in August. The Department of Agriculture and Consumer Services issued a warning about the snail this week.
