There are several animals that dont sleep, or at least dont sleep in the traditional sense. Here are some examples:

• Dolphins: Newborn dolphins dont sleep for a month after birth and stay alert with at least one eye open at all times. They can even swim while sleeping.

• Bullfrogs: Bullfrogs do sleep, but they do not exhibit the same types of sleep behaviors as mammals and birds. They do not have a distinct period of deep sleep, and they are able to remain alert and responsive to their environment at all times.

• Alpine swift: These birds have incredible migration habits and can fly continuously for 200 days straight.

• Bluefish: These high migratory species stop sleeping during their migration period.

• Rhopalocera (Butterflies): Butterflies dont sleep but go into a state of torpor which appears like sleep but is actually rest when they have slower heartbeat and a lower body temperature.

• Orca: Babies spend their first few months without any sleep. It is because babies need to keep their bodies warm, once they grow they rest and sleep.

• Giraffes: These beautiful creatures can survive all day with just 5 minutes of sleep.

• Fruit flies: These insects are able to remain active for long periods of time without needing rest. However, while they dont sleep in the traditional sense, some species do exhibit sleep-like states.

Its worth noting that while some animals may not sleep in the traditional sense, they may still experience periods of rest and reduced activity.
