Koalas. Hats off to the (somewhat disputed) king of sleep: the Koala bear. They've been reported to sleep up to 22 hours a day in captivity, over 90% of their lives. In the Australian wild, that figure may be closer to 14.5 hours of sleep daily, boosted by 5 additional hours of rest and inactivity.
Flamingos never fully sleep. Half of its brain is always awake and alert. We know this bird with brilliantly colored feathers can stand on one foot while awake. But what does it do when it's time to get some sleep?

That adds up to 4 hours and 48 minutes of sleep per day. The research also found that 80 percent of the ant workforce was awake and active at any one time.
Mosquitoes in the lab sleep a lot — between 16 and 19 hours a day depending on the species and the stimulation around them. Recognizing a sleeping mosquito takes some skill. When they're not looking for food, mosquitoes perch for long periods of time to conserve energy.

They react differently when external stimuli are applied while sleeping and while awake. But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger.

It was common practice in some populations to have “two sleep periods”; you could have the first snooze during the day and the second at night.
The fresh-water polyp Hydra vulgaris and the jellyfish Cassiopea are among the most primitive organisms in which sleep-like states have been observed. Observing sleep states in jellyfish provides evidence that sleep states do not require that an animal have a brain or central nervous system.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
