A team of biologists recently studied rainfrogs in the forests of northern Ecuador. “The three of us spotted it simultaneously,” Melissa Costales told TIME for Kids. She’s a conservation biologist. Her partners were scientist César Barrio-Amorós and reptile and amphibian guide Eric Osterman. “It took our brains a while longer than normal to recognize that we were watching an Atelopus mindoensis!” Their findings were published in the spring, in the journal Herpetology Notes. Herpetology is the study of reptiles and amphibians.
