Giraffes: They have been observed sleeping for only short periods of time, often standing up, and they can function well with minimal sleep due to their unique physiology.
Bullfrogs: These amphibians are often active both day and night, and they can go for long periods without sleeping.
Elephants: While elephants do sleep, they have very short periods of deep sleep, often standing up, and can go for several days with very little sleep.
Great White Sharks: Studies have shown that great white sharks have very little sleep compared to other animals, possibly due to their continuous movement and hunting habits.
Ants: They are known for their constant activity, and while they do rest, they take short breaks rather than prolonged periods of sleep.
Horses: They have adapted to sleep for short periods while standing up, which allows them to remain alert to potential threats while still getting some rest.
Cattle: Like other grazing animals, cattle have been observed sleeping for short periods throughout the day, often while standing, and can function well with minimal sleep.
