Auto-fellatio behaviour observed in the Indian Palm Squirrel Funambulus palmarum (Linnaeus, 1766)
Main Article Content
Abstract
Masturbation is an auto-sexual behaviour, a widespread phylogenetic trait in many taxa. Masturbation in squirrels was rarely reported. We observed an Indian palm squirrel (Funambulus palmarum) doing the auto-fellatio activity away from the scurry in Bhavanisagar, Tamil Nadu. However, the auto-fellatio behaviour in F. palmarum is novel.
