The African clawed frog (Xenopus laevis), also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
The clade name Pythonoidea emphasizes the relatively close evolutionary relationship among these 43 species, which last shared a common ancestor about 62 [CI: 46-78] million years ago, in contrast to the more distant relationship between pythonoids and their next closest relatives, uropeltoids (the most recent common ancestor between pythonoids ...
All species of Xenopus have flattened, somewhat egg-shaped and streamlined bodies, and very slippery skin (because of a protective mucus covering). [6] The frog's skin is smooth, but with a lateral line sensory organ that has a stitch-like appearance. The frogs are all excellent swimmers and have powerful, fully webbed toes, though the fingers ...
This is a list of all extant genera, species, and subspecies of the snakes of the family Pythonidae, otherwise referred to as pythonids or true pythons.It follows the taxonomy currently provided by ITIS, [1] which is based on the continuing work of Roy McDiarmid [2] and has been updated with additional recently described species.
Python is a genus of constricting snakes in the Pythonidae family native to the tropics and subtropics of the Eastern Hemisphere. [1] The name python was proposed by François Marie Daudin in 1803 for non-venomous flecked snakes. [2] Currently, 10 python species are recognized as valid taxa. [3]
Müller's platanna (Xenopus muelleri), also known as Müller's clawed frog, [3] [4] is a species of frog in the family Pipidae found in Angola, Benin, Botswana, Burkina Faso, Cameroon, the Central African Republic, Chad, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Eswatini, Ghana, Kenya, Malawi, Mozambique, Namibia, Nigeria, South Africa, Sudan, Tanzania, Togo ...
The Lake Oku clawed frog (Xenopus longipes) is a species of frog in the family Pipidae, endemic to Lake Oku, a small crater lake in northwest Cameroon. [1] [2] [3] It is a small, dark-coloured, fully aquatic frog with a length of 28 to 36 mm (1.1 to 1.4 in), males being slightly smaller than females.
It is the only species in the genus Xenopus to have a diploid genome. [3] [4] Its genome has been sequenced, [5] [6] making it a significant model organism for genetics that complements the related species Xenopus laevis (the African clawed frog), [7] a widely used vertebrate model for developmental biology.
