'''Lordosis behavior''' ({{IPAc-en|l|ɔːr|ˈ|d|oʊ|s|ɪ|s}}<ref name="American Heritage Dictionary - lordosis"/>), also known as '''mammalian lordosis''' (Greek lordōsis, from ''lordos'' "bent backward"<ref name="American Heritage Dictionary - lordosis">{{cite web|url=https://ahdictionary.com/word/search.html?q=lordosis|publisher=The American Heritage Dictionary|title=lordosis|access-date=January 3, 2017|archive-url=https://web.archive.org/web/20170104090839/https://ahdictionary.com/word/search.html?q=lordosis|archive-date=January 4, 2017|url-status=dead}}</ref>) or '''presenting''', is the naturally occurring body posture for sexual receptivity to [[Copulation (zoology)|copulation]] present in females of most [[mammal]]s including [[rodents]], [[elephants]], and [[Felidae|cats]]. The primary characteristics of the behavior are a lowering of the forelimbs but with the rear limbs extended and [[hip]]s raised, [[ventral]] arching of the [[Vertebral column|spine]] and a raising, or sideward displacement, of the [[tail]]. During lordosis, the spine curves [[dorsoventral]]ly so that its apex points towards the abdomen.
