Are the Mazama Newts Poisonous?
Mazama Newts found their way to Crater Lake as early as 6000 years ago when there were no fish or crayfish predators. It takes valuable energy for the newts to produce the toxin and food resources for the newts in Crater Lake are scarce. The Mazama Newt may have lost its' toxicity due to the lack of predation and the general scarcity of food in Crater Lake .
