What animals are not active?

Animals that are not active typically include those that are nocturnal, crepuscular, or exhibit low levels of activity due to their lifestyle or environmental adaptations. Examples include sloths, which are known for their slow movements and long hours of rest, and certain reptiles like snakes that may remain motionless for extended periods while hunting or basking. Additionally, deep-sea creatures often have low metabolic rates and are less active due to the extreme conditions of their habitats.
