Knowra Ranidae Ranidae Ranidae is a family of frogs commonly called true frogs, distributed across every continent except Antarctica. Its members include aquatic, terrestrial, and arboreal species.
Anura : An order of amphibians comprising frogs and toads, characterized by adults that lack tails. Ranidae is one family within this broader group of amphibians.
Rana : A genus of frogs that includes the common frogs of Europe and several other species. This genus contains some of the best-known frogs traditionally placed in Ranidae.
Ceratophryidae : A family of mostly South American frogs that includes the large, wide-mouthed horned frogs. These terrestrial ambush predators contrast with many ranids’ longer-legged, more aquatic forms.
Bioindicator : An organism whose presence, absence, or condition provides information about environmental quality. Ranid population changes can signal pollution, habitat alteration, or infectious disease.
Amphibia : A class of vertebrates that includes frogs, salamanders, and caecilians. Ranids are amphibians, sharing this class’s basic life-history traits.
Lithobates : A genus of North and Central American frogs that includes the American bullfrog. Its species illustrate the large-bodied aquatic frogs found in the family.
Hylidae : A large family of frogs that includes many tree frogs, with adhesive toe pads common in climbing species. Hylids are a neighboring frog family, often more specialized for climbing than ranids.
Environmental DNA : Genetic material collected from environmental samples such as water, soil, or air to detect organisms. Water samples can reveal ranid species without capturing or directly observing them.
Frog : A tailless amphibian with a short body and hind limbs adapted for jumping or swimming. Ranidae is one of the principal families included in the familiar category of frogs.
Pelophylax : A genus of frogs native mainly to Europe, North Africa, and western Asia, including the edible frog. Its water frogs are familiar examples of Eurasian ranid diversity.
