Knowra Frog Frog Frogs are tailless amphibians in the order Anura, typically characterized by powerful hind legs, prominent eyes, and bodies adapted for jumping or swimming.
Anura : The amphibian order comprising frogs and toads, distinguished from salamanders by the absence of a tail in adults. Frogs belong to this order; “frog” is a common name within its diversity.
Frog locomotion : The ways frogs move, including jumping, walking, climbing, swimming, and burrowing. Powerful hind limbs enable the characteristic leaps of many frogs, though movement varies widely.
Xenopus laevis : An African clawed frog widely used in developmental biology, cell biology, and embryology research. Its large eggs and embryos made it a major laboratory model.
Toad : A common name for certain frogs, especially species with stout bodies and relatively dry, warty skin. Toads are frogs in biological classification, though everyday usage often contrasts them with smoother, longer-legged frogs.
Goliath frog : A large frog native to Cameroon and Equatorial Guinea, the largest living frog by mass. It illustrates how far frog size can exceed the familiar small garden species.
Amphibia : The vertebrate class that includes frogs, salamanders, and caecilians, generally associated with aquatic reproduction and permeable skin. Frogs are amphibians, sharing this broader lineage’s distinctive biology.
Frog respiration : Gas exchange in frogs through the lungs, skin, and the lining of the mouth and throat. Frogs combine lung breathing with cutaneous gas exchange.
Xenopus tropicalis : A diploid African clawed frog used in research, notable for its relatively compact genome among model vertebrates. It extends frog research with a tractable genome and experimental development.
Salamander : An amphibian in the order Caudata, typically retaining a tail as an adult and having an elongated body. Salamanders are amphibians like frogs but retain tails and belong to a different order.
Wood frog : A North American frog capable of surviving partial freezing during winter. Its freeze tolerance is an unusual adaptation among vertebrates.
