I remember my older daughter, who was 3 at the time, finding and gently holding a red eft like this one after a thunderstorm while camping in Pennsylvania. (Red efts tend to come out after rain.) That was 15 years ago. Today, red efts and all of North America’s salamanders are in peril. The threat of a deadly disease is looming. Tomorrow, you can hear about scientists’ efforts to protect them. (Photo: iStock.)
