It seems you can teach an old quoll new tricks. Australian scientists have successfully taught the endangered marsupial to avoid eating toxic cane toads. Ecologists at Sydney University say they trained the animal to suppress its instincts and refuse to eat the deadly invasive amphibians.
Researchers conditioned the quolls by feeding them very small toads tainted with the nauseating toxin. The animals were tagged and released into the wild, and scientists report that the conditioned quolls survive up to five times longer than unconditioned ones.
