Cathemeral animals

22 species

Cathemerality, sometimes called metaturnality, is the behavior in which an organism has sporadic and random intervals of activity during the day or night. Many animals do not fit the traditional definitions of being strictly nocturnal, diurnal, or crepuscular, often driven by factors that include the availability of food, predation pressure, and variable ambient temperature. This activity pattern is seen in lions, coyotes, and lemurs. The main factors that influence whether or why an animal behaves cathemerally include resource variation, food quality, photoperiodism, nocturnal luminosity, temperature, predator avoidance, and energetic constraints.
