Clawed frogs have powerful legs that help them move quickly both underwater and on land. Feral clawed frogs in South Wales have been found to travel up to 2 kilometres (1.2 mi) between locations. [11] The feet of Xenopus species have three black claws on the last three digits. These claws are used to rip apart food and scratch predators.
These frogs have tiny black claws on their hind legs, which caused one of their discoverers, Oskar Boettger, to originally call them African dwarf clawed frogs, [5] but they quickly lose these black tips in the sharp pebble environments and are more commonly called African dwarf frogs today. African Dwarf Frogs can swim up to 4 miles per hour ...

Amphibians have soft bodies with thin skins, and lack claws, defensive armour, or spines. Nevertheless, they have evolved various defence mechanisms to keep themselves alive. The first line of defence in salamanders and frogs is the mucous secretion that they produce.
Hymenochirus boettgeri, also known as the Zaire dwarf clawed frog [2] or the Congo dwarf clawed frog, [1] is a species of frog in the family Pipidae.It is found in Nigeria, Cameroon, Equatorial Guinea, Gabon, and east to the Central African Republic and to eastern Democratic Republic of the Congo.
The hairy frog is also notable in possessing retractable "claws", which it may project through the skin, apparently by intentionally breaking the bones of the toe. [5] These are not true claws, as they are made of bone, not keratin. In addition, there is a small bony nodule nestled in the tissue just beyond the frog's fingertip.
The frogs are all excellent swimmers and have powerful, fully webbed toes, though the fingers lack webbing. Three of the toes on each foot have conspicuous black claws. The frog's eyes are on top of the head, looking upwards. The pupils are circular.
