Cane Toads are an invasive species where they were introduced as natural predators to feed on beetles that were killing off sugarcane in Florida and Australia in the 1930s. The plan backfired since Cane Toads did not focus on the bugs and mostly feed on native species, reproduce quickly, and invaded more territory than planned.
