Leptodactylidae

Leptodactylidae is a family of frogs native to the Americas, including species that build foam nests or burrow. Its members occupy habitats ranging from tropical forests to open grasslands.

Anura: Anura is the amphibian order comprising frogs and toads, characterized in adults by tailless bodies and powerful hind limbs. Leptodactylidae is one of the many families within this order.
Foam nest: A foam nest is a mass of bubbles enclosing eggs or larvae, produced by some amphibians and other animals. Several leptodactylids whip secretions into foam that protects developing eggs.
Ceratophrys cranwelli: Ceratophrys cranwelli, the Cranwell's horned frog, is a large, round-bodied South American frog in the family Ceratophryidae. Its similar South American range makes it a useful example of a frog outside Leptodactylidae.
Amphibian decline: Amphibian decline is the widespread reduction of amphibian populations and species, driven by interacting environmental pressures. Leptodactylid species face habitat loss, disease, and other pressures across the Americas.
Neobatrachia: Neobatrachia is a large clade containing most living frog species. Leptodactylidae belongs to this major frog clade.
Parental care in amphibians: Parental care in amphibians comprises behaviors that protect or provision eggs and young. Some leptodactylid species guard nests or tadpoles, extending reproduction beyond egg laying.
Lithobates catesbeianus: Lithobates catesbeianus, the American bullfrog, is a large ranid frog native to eastern North America. Its familiar pond-breeding strategy contrasts with the foam nests of many leptodactylids.
Chytridiomycosis: Chytridiomycosis is a lethal amphibian disease caused by chytrid fungi, including Batrachochytrium dendrobatidis. This disease has contributed to declines in some leptodactylid populations.
Amphibia: Amphibia is a vertebrate class that includes frogs, salamanders, and caecilians. The family belongs to this broader group of mostly moisture-dependent vertebrates.
Burrowing frog: A burrowing frog is a frog adapted to excavate or occupy underground refuges. Burrowing occurs in several leptodactylid lineages and helps frogs withstand dry periods.
