Alpine Swifts- These birds spend most of their lives flying and only sleep for short periods when flying at high altitudes.

Dolphins: Baby Dolphins don't sleep for a month; they remain alert even with one eye open. 

Elephants: Elephants require a minimum of three to four hours of daily sleep, and can skip a night without needing to nap the next day.

Woolly Spider Monkeys: Female woolly spider monkeys may have high mortality rates during childbirth, with complications and predation being contributing factors.

Cuttlefish: Similar to other cephalopods, cuttlefish may experience senescence and death shortly after mating and laying eggs.

Bullfrogs: These frogs can live for weeks or months without taking sleep. 

Giraffes: Giraffes typically sleep around 8% of their day and can go several weeks without rest.
