Poison frog call to feed tadpole evolutionarily derived from other calls, research finds
Many animals produce sounds to communicate with others, often for the purpose of attracting mates, or warning others of nearby predators. Sometimes calls evolve for new and unique purposes, such as the egg-feeding calls of Ranitomeya imitator, otherwise known as the mimic poison frog. While the behaviors surrounding this call have been documented in observations by both natural historians and hobbyist pet owners, the call itself had not been previously characterized.
