[[Diurnal]] animals do it the other way around. '''Crepuscular''' animals are mostly active near [[dawn]], [[dusk]], and sometimes when the full [[moon]] throws light. Domestic cats hunt mice and [[vole]]s mostly at this time. '''Cathemeral''' animals are equally likely to be awake and active at any time of day or night. Many nocturnal animals have good [[night vision]]. Their large eyes may be highly reflective when a bright light flashes on them. [[Owls]] and [[bats]] are typical nocturnal predators. More specifically, they have a larger [[cornea]] relative to their eye size than diurnal creatures. This increases their visual sensitivity in low-light conditions.<ref name=HallEtAl>{{cite journal|last1=Hall |first1=M. I. |last2=Kamilar |first2=J. M. |last3=Kirk |first3=E.
