Final answer:
Rabbits are crepuscular, meaning they are most active at dawn and dusk, which differs from nocturnal and diurnal animals that are active at night and during the day, respectively.
Step-by-step explanation:
Since rabbits are most active at dusk and dawn, they are classified as crepuscular. This term refers to animals that are primarily active during the twilight hours, which occurs around sunrise and sunset. The daily cycles of behavior that dictate when an animal is active are known as circadian rhythms. Diurnal animals, like many mammals and birds, are active during the day, while nocturnal animals, such as bats and coyotes, are active at night. Crepuscular animals, like rabbits, are in a category of their own, specifically adapted to thrive during the low-light conditions of dusk and dawn.
