Phyllomedusidae: A family of neotropical tree frogs that includes Agalychnis and related genera. Agalychnis belongs to this family, whose members share distinctive adaptations to life in trees.
Red-eyed tree frog: A Central American frog, Agalychnis callidryas, with bright red eyes and green skin. This widely recognized species is the best-known member of Agalychnis.
Amplexus: The mating embrace in frogs and toads, in which a male holds a female during egg fertilization. Agalychnis frogs use this mating posture during reproduction.
Chytridiomycosis: A disease of amphibians caused by chytrid fungi, especially Batrachochytrium dendrobatidis. Chytridiomycosis has contributed to declines in some Central American Agalychnis populations.
Anura: The amphibian order comprising frogs and toads, characterized by adults with short bodies and no tails. This broader group places Agalychnis among frogs and toads rather than other amphibians.
Agalychnis annae: A Central American tree frog with blue-green coloration, found in Costa Rica and western Panama. Its range and appearance show the diversity beyond the red-eyed tree frog.
Oviparity: Reproduction by laying eggs that develop outside the parent’s body. Agalychnis lays eggs rather than giving birth to live young.
Deforestation: The removal or permanent clearing of forest cover. Forest loss removes the humid canopy habitats on which Agalychnis depends.
Amphibian: A vertebrate that typically has an aquatic larval stage and undergoes metamorphosis into an adult. Agalychnis species develop from aquatic tadpoles into terrestrial or arboreal adults.
Agalychnis saltator: A tree frog from Central America, notable for its ability to leap between branches. Its jumping behavior highlights locomotor variation among species in the genus.
