Biologists from Idaho and Canada are working to slow the spread of an invasive species. But what they're after and how they're catching them, may shock you.
Bullfrogs spread disease, eat just about anything in their path, and are causing other native amphibians to struggle. So to cull their populations in Northern Idaho, biologists are using a technique called "Elctrofrogging" to zap and stun the slimy creatures in the water so they can euthanize them later. Biologists say this is an emergency measure to temporarily stop bullfrogs from expanding their habitat.
"The long-term plan is to create some habitat that will benefit ar native amphibians but will preclude bullfrogs from breeding," said Idaho Fish and Game Biologist Michael Lucid.
