KOOKABURRA 
          KILLER? 
          The cane toad has poison glands situated on its shoulders. When a predator 
          tries to swallow a cane toad, the glands ooze a potent toxin. The predator's 
          heart begins to race - it begins to drool uncontrollably - it finds 
          it hard to breathe - rather like a Ricky Martin concert. Both domestic 
          and native animals can die in as little as 15 minutes. Wildlife experts 
          increasingly find kookaburras, a native frog-eating bird, dead in the 
          wild with cane toads still lodged in their gullets. Is it a threat to 
          man? "I wouldn't eat one headfirst," an authority cautions.
