Distribution of Pipidae in black

The Pipidae are a family of primitive, tongueless frogs. The 41 species in the family Pipidae are found in tropical South America (genus Pipa) and sub-Saharan Africa (the three other genera).

Description

Pipid frogs are highly aquatic and have numerous morphological modifications befitting their habitat. For example, the feet are completely webbed, the body is flattened, and a lateral line system is present in adults.[1] In addition, pipids possess highly modified ears for producing and receiving sound under water. They lack a tongue or vocal cords, instead having bony rods in the larynx that help produce sound. They range from 4 to 19 cm (1.6 to 7.5 in) in body length.[2]

Extant genera

  • Hymenochirus Boulenger 1896 - dwarf clawed frogs (4 species)
  • Pipa Laurenti 1768 - Surinam toads (7 species)
  • Pseudhymenochirus Chabanaud 1920 - Merlin's dwarf gray frog or Merlin's clawed frog (1 species)
  • Xenopus Wagler 1827 - clawed frogs (29 species)[4]
    • Subgenus (Silurana) Wagler 1827 - common clawed frogs
    • Subgenus (Xenopus) Gray 1864 - tropical clawed frogs

Fossil record

The fossil record for pipids and close relatives (Pipimorpha) is relatively good, with several extinct species known.[5] Six of these are placed in the extant genus Xenopus, the remainder in extinct genera. These fossils are known from Africa, South America, and the Middle East back to the Lower Cretaceous.[2][5]
