=== Gliding ===
During the evolutionary history of frogs, several different groups have independently taken to the air.<ref>{{cite journal |author1=Emerson, Sharon B. |author2=Koehl, M. A.

Typical of them is [[Rhacophorus nigropalmatus|Wallace's flying frog]] (''Rhacophorus nigropalmatus'') from Malaysia and Borneo. It has large feet with the fingertips expanded into flat adhesive discs and the digits fully webbed. Flaps of skin occur on the lateral margins of the limbs and across the tail region. With the digits splayed, the limbs outstretched, and these flaps spread, it can glide considerable distances, but is unable to undertake powered flight.<ref>{{cite web |url=http://amphibiaweb.org/cgi-bin/amphib_query?where-genus=Rhacophorus&where-species=nigropalmatus |title=''Rhacophorus nigropalmatus'' |date=November 29, 2001 |author1=Shah, Sunny |author2=Tiwari, Rachna |work=AmphibiaWeb |publisher=University of California, Berkeley |access-date=June 11, 2012}}</ref> It can alter its direction of travel and navigate distances of up to {{convert|15|m|ft|round=5|abbr=on}} between trees.<ref>{{cite web |url=http://animals.nationalgeographic.com/animals/amphibians/wallaces-flying-frog/ |archive-url=https://web.archive.org/web/20100118144053/http://animals.nationalgeographic.com/animals/amphibians/wallaces-flying-frog |url-status=dead |archive-date=January 18, 2010 |title=Wallace's Flying Frog ''Rhacophorus nigropalmatus'' |publisher=National Geographic: Animals |access-date=June 5, 2012|date=September 10, 2010 }}</ref>
