Rana is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Rana (genus)_sentence_2

Members of this genus are found through much of Eurasia and western North America. Rana (genus)_sentence_3

Many other genera were formerly included here. Rana (genus)_sentence_4

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. Rana (genus)_sentence_5

They are excellent jumpers due to their long, slender legs. Rana (genus)_sentence_6

The typical webbing found on their hind feet allows for easy movement through water. Rana (genus)_sentence_7

Coloration is mostly greens and browns above, with darker and yellowish spots. Rana (genus)_sentence_8

Distribution and habitat Rana (genus)_section_0

Many frogs in this genus breed in early spring, although subtropical and tropical species may breed throughout the year. Rana (genus)_sentence_9

Males of most of the species are known to call, but a few species are thought to be voiceless. Rana (genus)_sentence_10

Females lay eggs in rafts or large, globular clusters, and can produce up to 20,000 at one time. Rana (genus)_sentence_11

Diet Rana (genus)_section_1

Rana species feed mainly on insects and invertebrates, but swallow anything they can fit into their mouths, including small vertebrates. Rana (genus)_sentence_12

Among their predators are egrets, crocodiles, and snakes. Rana (genus)_sentence_13

Systematics Rana (genus)_section_2

Some 50 to 100 extant species are now placed in this genus by various authors; many other species formerly placed in Rana are now placed elsewhere. Rana (genus)_sentence_14

Frost restricted Rana to the Old World true frogs and the Eurasian brown and pond frogs of the common frog R. temporaria group, although other authors disagreed with this arrangement. Rana (genus)_sentence_15

In 2016, a consortium of Rana researchers from throughout Europe, Asia, and North America revised the group, and reported that the arrangement of Frost (2006) resulted in nonmonophyletic groups. Rana (genus)_sentence_16

Yuan et al. Rana (genus)_sentence_17

(2016) included all the North American ranids within Rana, and used subgenera for the well-differentiated species groups within Rana. Rana (genus)_sentence_18

Both of these classifications are presented below. Rana (genus)_sentence_19

Genera recently split from Rana are Babina, Clinotarsus (including Nasirana), Glandirana, Hydrophylax, Hylarana, Lithobates, Odorrana (including Wurana), Pelophylax, Pulchrana, Sanguirana, and Sylvirana. Rana (genus)_sentence_20

Of these, Odorrana is so closely related to Rana proper, it could conceivably be included here once again. Rana (genus)_sentence_21

The others seem to be far more distant relatives, in particular Pelophylax. Rana (genus)_sentence_22

New species are still being described in some numbers. Rana (genus)_sentence_23

A number of extinct species are in the genus, including Rana basaltica, from Miocene deposits in China. Rana (genus)_sentence_24

Species Rana (genus)_section_3

The following species are recognised in the genus Rana: Rana (genus)_sentence_25

Alternative classifications Rana (genus)_section_4

AmphibiaWeb includes the following species, arranged in subgenera: Rana (genus)_sentence_26

Notes on other taxonomic arrangements: Rana (genus)_sentence_27

The harpist brown frog, Kampira Falls frog, or Yaeyama harpist frog was formerly known as R. psaltes; it was subsequently identified as the long-known R. okinavana. Rana (genus)_sentence_28

The latter name has been misapplied to the Ryūkyū brown frog, but the harpist brown frog is a rather distinct species that apparently belongs in Babina or Nidirana if these are considered valid. Rana (genus)_sentence_29
