Here are 10 animals known for their minimal or nonexistent sleep patterns, highlighting the amazing adaptability of nature:
2
Alpine Swifts: These birds can stay in the air for months at a time, catching short naps while flying.
3
Ants: Some species of ants have extremely short sleep cycles; queens take quick naps, while worker ants may stay awake for long stretches.
4
Bullfrogs: Famous for going months without sleep, these frogs exhibit extraordinary endurance.
5
Deer: During migrations or when predators are nearby, deer can significantly reduce their sleep.
6
Dolphins: Dolphins engage in unihemispheric slow-wave sleep, allowing one half of their brain to rest while the other stays alert.
7
Elephants: With only around two hours of sleep each day, elephants stay active, often maintaining social bonds and traveling in groups.
8
Horses: Horses can sleep while standing and require only about two hours of REM sleep each day, which helps them stay alert to potential dangers.
9
Giraffes: Needing only a few minutes to two hours of sleep daily, giraffes remain vigilant, with their height providing an advantage in spotting predators.
10
Sharks: Some shark species need to keep moving to breathe, so they don’t sleep in the traditional sense but instead experience reduced activity while remaining partially alert.
