Learn about how Frogs & Toads are considered "bioindicators"

The name “milk frog” comes from the milky white secretion this frog produces when threatened, which can be poisonous to predators. Milk frogs are a light gray color with brown and black banding. Juveniles will show a stronger contrast in colors, which will fade as they mature. Like most frogs, male milk frogs are smaller than females. They are also nocturnal and arboreal (live in trees). In addition, milk frogs have developed sticky pads on their toes that aid them in climbing on leaves and trees. Females typically lay a clutch of about 2,000 eggs, and the male will care for them until they hatch. Once the eggs have hatched, the tadpoles will take approximately three weeks to metamorphose into their juvenile form.
