In zoology, a crepuscular animal is one that is active primarily during the twilight period, [1] being matutinal, vespertine/vespertinal, or both. This is distinguished from diurnal and nocturnal behavior, where an animal is active during the hours of daytime and of night, respectively.
The dark blue, teal, and gold tapetum lucidum from the eye of a cow Retina of a mongrel dog with strong tapetal reflex.

Its most distinctive feature is its unusually large ears, which serve to dissipate heat and listen for underground prey. The fennec is the smallest fox species. Its coat, ears, and kidney functions have adapted to the desert environment with high temperatures and little water. The fennec fox mainly eats insects, small mammals and birds. It has ...
The gray fox (Urocyon cinereoargenteus), or grey fox, is an omnivorous mammal of the family Canidae, widespread throughout North America and Central America.This species and its only congener, the diminutive island fox (Urocyon littoralis) of the California Channel Islands, are the only living members of the genus Urocyon, which is considered to be genetically sister to all other living canids.
Foxes are sly, mischievous creatures—ones that do not intentionally fraternize with humans. So, spotting one in the wild is rare, as well as lucky. "There is a reason [for seeing one]," Mello says.
Many animals have better night vision than humans do, the result of one or more differences in the morphology and anatomy of their eyes. These include having a larger eyeball, a larger lens, a larger optical aperture (the pupils may expand to the physical limit of the eyelids), more rods than cones (or rods exclusively) in the retina , and a ...
Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night. Matutinal, a classification of organisms that are only or primarily active in the pre-dawn hours or early night.
Fennec foxes (and other species of fox adapted to life in the desert, such as kit foxes), for example, have large ears and short fur to aid in keeping the body cool. [ 2 ] [ 9 ] Arctic foxes , on the other hand, have tiny ears and short limbs as well as thick, insulating fur, which aid in keeping the body warm. [ 10 ]
