Nocturnal animals: adaptations to life in the dark
What they are - biological definition
They are animal species that have an active life at night and sleep during the day. These animals usually hunt, breed and move around at night. The nightlife habit occurs due to physiological, food or reproductive needs. Some species, for example, have nocturnal habits as a strategy for not being caught by predators of daytime habits.
Although many nocturnal species have nocturnal habits, they also manage to stay active during the day. Or they do few activities during the day and major activities at night.
