Editing Xenopus (section)

===Behaviour===
''Xenopus'' species are entirely [[Aquatic animal|aquatic]], though they have been observed migrating on land to nearby bodies of water during times of [[drought]] or in heavy rain. They are usually found in [[lake]]s, [[river]]s, [[swamps]], potholes in streams, and man-made reservoirs.<ref name="passmore"/>

Adult frogs are usually both [[predator]]s and [[scavengers]], and since their tongues are unusable, the frogs use their small fore limbs to aid in the feeding process. Since they also lack [[vocal sac]]s, they make clicks (brief pulses of sound) underwater (again similar to ''[[Pipa pipa]]'').<ref name="noc-ani"/> Males establish a hierarchy of social dominance in which primarily one male has the right to make the advertisement call.<ref name="tobias-compet">{{cite journal | vauthors = Tobias ML, Corke A, Korsh J, Yin D, Kelley DB | title = Vocal competition in male Xenopus laevis frogs | journal = Behavioral Ecology and Sociobiology | volume = 64 | issue = 11 | pages = 1791–1803 | date = November 2010 | pmid = 21442049 | pmc = 3064475 | doi = 10.1007/s00265-010-0991-3 }}</ref> The females of many species produce a release call, and ''[[Xenopus laevis]]'' females produce an additional call when sexually receptive and soon to lay eggs.<ref name="tobias-rap">{{cite journal | vauthors = Tobias ML, Viswanathan SS, Kelley DB | title = Rapping, a female receptive call, initiates male-female duets in the South African clawed frog | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 95 | issue = 4 | pages = 1870–1875 | date = February 1998 | pmid = 9465109 | pmc = 19205 | doi = 10.1073/pnas.95.4.1870 | doi-access = free | bibcode = 1998PNAS...95.1870T }}</ref> The ''Xenopus'' species are also active during the twilight (or [[crepuscular]]) hours.<ref name="passmore"/>

During breeding season, the males develop ridge-like nuptial pads (black in color) on their fingers to aid in grasping the female. The frogs' mating embrace is inguinal, meaning the male grasps the female around her waist.<ref name="passmore"/>
