No, all animals need some form of rest to function properly. However, there are certain animals like sharks and some types of fish that have the ability to rest while still swimming, allowing them to remain active for long periods without fully sleeping. Additionally, some animals like giraffes and horses can sleep while standing up, which allows them to stay alert and avoid danger while still getting some rest. But in all cases, even if an animal is not fully sleeping, they still need some form of rest or downtime to maintain their health and wellness.
