Rana is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Members of this genus are found through much of Eurasia and western North America. Many other genera were formerly included here. These true frogs are usually largish species characterized by their slim waists and wrinkled skin; many have thin ridges running along their backs, but they generally lack "warts" as in typical toads. They are excellent jumpers due to their long, slender legs. The typical webbing found on their hind feet allows for easy movement through water. Coloration is mostly greens and browns above, with darker and yellowish spots.
The pickerel frog is a small North American frog, characterized by the appearance of seemingly "hand-drawn" squares on its dorsal surface. Pickerel frogs are the only poisonous frog native to the United States.
The California red-legged frog is a species of frog found in California (USA) and northern Baja California (Mexico). It was formerly considered a subspecies of the northern red-legged frog. The frog is an IUCN near-threatened species as of 2021, has a NatureServe conservation status of Imperiled as of 2015, and is a federally listed threatened species of the United States that is protected by law.
The agile frog is a European frog in the genus Rana of the true frog family, Ranidae.
The northern red-legged frog is a species of amphibian whose range is the coastal region stretching from southwest British Columbia to southern Mendocino County in Northern California, and is protected in Oregon and California. As a member of the genus Rana, this species is considered a true frog, with characteristic smooth skin and a narrow waist. This frog requires still waters for breeding, and is rarely found at any great distance from its breeding ponds or marshes.
The Amami tip-nosed frog is a species of frog in the family Ranidae. It is endemic to the Amami Islands, a part of the Ryukyu Islands, Japan. Specifically, it is known from the islands of Amamioshima and Tokunoshima.
Odorrana bolavensis is a species of frog in the family Ranidae. It is endemic to the Bolaven Plateau, Laos. Its natural habitats are wet evergreen forest. It can be found at night on rocks and vegetation along rocky streams, occasionally on leaf-litter or tree branches away from streams.
Papurana garritor is a species of frog in the family Ranidae. It is endemic to New Guinea and widely distributed, found in both Indonesian and Papua New Guinean parts of the island. Common name Eilogo Estate frog has been coined for it.
The Iberian frog, also known as Iberian stream frog, is a species of frog in the family Ranidae found in Portugal and Spain. Its natural habitats are rivers, mountain streams and swamps. It is threatened by habitat loss, introduced species, climate change, water contamination, and increased ultraviolet radiation.
Johns' groove-toed frog or Johns' frog, is a frog species in the true frog family (Ranidae). It is found in scattered locations in southern China and Vietnam and in the Khammouan Province of Laos, eastern Cambodia, and north-central Thailand. Its natural habitats are subtropical or tropical evergreen forests where it can be found in leaf-litter and on low vegetation near streams. It breeds in paddy fields, at least. It is mostly known from protected areas without other major threats than fires. It is not considered threatened by the IUCN.
Odorrana supranarina is a species of frog in the family Ranidae. It is endemic to Ryukyu Archipelago, Japan, and is known from the islands of Ishigaki and Iriomote, both in the Yaeyama Group. The specific name supranarina refers to the large size of this species —at the time of the species description, it was the largest member of the so-called Rana narina complex.

Chalcorana chalconota is a species of "true frog", family Ranidae. It is endemic to Indonesia and occurs in southern Sumatra, Java, Bali, and a few smaller islands. Populations previously assigned to this species now belong to a number of other Chalcorana species, leading to the current delineation of Chalcorana chalconota with a much narrower range. This species is also known as the Schlegel's frog, brown stream frog, copper-cheeked frog, or, among with many other species, white-lipped frog.
Sanguirana igorota is a species of true frog, family Ranidae. It is endemic to Cordillera Central of the island of Luzon, Philippines. Its closest relative is Sanguirana luzonensis, and it has even been considered synonym of that species; a later study suggests still unresolved relationships between S. igorota, S. luzonensis, and S. tipanan. Common name Taylor's Igorot frog has been coined for this species.
Papurana milneana is a species of "true frog", family Ranidae. It is endemic to Papua New Guinea where it is found in the upland areas of Milne Bay, Morobe, Northern, and Central Provinces, as well from the D'Entrecasteaux Islands and, tentatively, Louisiade Archipelago. It was originally described as a subspecies of Rana grisea, but raised to full-species status in 2007.
Rana ulma is a species of frog in the family Ranidae. It is endemic to Okinawa Islands, in the central Ryukyu Islands of Japan. It is currently only known from northern Okinawa Island and from Kume Island. Common names Okinawa frog and Ryukyu brown frog have been used for this species; the latter can refer to this species or to Rana kobai. The specific name ulma means "coral island" in Uruma dialect of Okinawa.
