The '''red fox''' ('''''Vulpes vulpes''''') is the largest of the [[true fox]]es and one of the most widely distributed members of the order [[Carnivora]], being present across the entire [[Northern Hemisphere]] including most of [[North America]], [[Europe]] and [[Asia]], plus parts of [[North Africa]]. It is listed as [[least concern]] on the [[IUCN Red List]].<ref name=IUCN/> Its range has increased alongside human expansion, having been [[Foxes in Australia|introduced to Australia]], where it is considered harmful to native mammals and bird populations. Due to its presence in Australia, it is included on the list of the "[[List of the world's 100 worst invasive species|world's 100 worst invasive species]]".<ref>{{cite web |title=100 of the World's Worst Invasive Alien Species |url=http://www.issg.org/database/species/ecology.asp?si=66&fr=1&sts=&lang=EN |publisher=Invasive Species Specialist Group |access-date=17 March 2011 |archive-date=16 March 2017 |archive-url=https://web.archive.org/web/20170316113132/http://issg.org/database/species/ecology.asp?si=66&fr=1&sts=&lang=EN |url-status=dead }}</ref>

===Dimensions===
Red foxes are the largest species of the genus ''Vulpes''.<ref name="z129">{{Harvnb|Sillero-Zubiri|Hoffman|MacDonald|2004|p=129}}</ref> However, relative to dimensions, red foxes are much lighter than similarly sized dogs of the genus ''[[Canis]]''. Their limb bones, for example, weigh 30 percent less per unit area of bone than expected for similarly sized dogs.<ref name="rwf1987">{{Cite book|title=Running with the Fox|last=Macdonald|first=David|publisher=Unwin Hyman, London |year=1987 |language=en |isbn=9780044401995 |page={{page needed|date=August 2020}}}}</ref> They display significant individual, sexual, age and geographical variation in size. On average, adults measure {{cvt|35|–|50|cm}} high at the shoulder and {{cvt|45|-|90|cm}} in body length with tails measuring {{cvt|30|-|55.5|cm}}. The ears measure {{cvt|7.7|-|12.5|cm}} and the hind feet {{cvt|12|-|18.5|cm}}. Weights range from {{cvt|2.2|-|14|kg}}, with vixens typically weighing 15–20% less than males.<ref name=r10>{{cite book|author=Nowak, Ronald M.|title=Walker's Mammals of the World|url=https://books.google.com/books?id=T37sFCl43E8C&q=eurasian+lynx+38+kg&pg=PA806|page=636|volume=2|publisher=JHU Press|year=1999|isbn=978-0-8018-5789-8}}</ref><ref name="Burnie">Burnie, D. & Wilson, D.
