Megabats use smell to find food sources like fruit and nectar.<ref name="Jones"/> They have keen senses of smell that rival that of the [[domestic dog]].<ref name="Schwab">{{cite journal|doi=10.1136/bjo.2005.077966|pmid=16267906|pmc=1772916|title=A choroidal sleight of hand|journal=[[British Journal of Ophthalmology]]|volume=89|issue=11|page=1398|year=2005|last1=Schwab|first1=I.
