The animal kingdom is full of intriguing adaptations, with some species needing little to no sleep. Here’s a look at ten animals with minimal or unique sleep patterns.
Ants
Some ant species have very short sleep cycles. Queens take quick naps, while workers stay active for long periods, ensuring the colony’s activities continue smoothly.
Bullfrogs
Bullfrogs can go months without sleep, staying alert to environmental cues and threats, with occasional restful moments instead of deep sleep.
Deer
Deer reduce sleep during migration or in the presence of predators. They maintain a semi-alert state, ready to flee at the slightest disturbance.
Dolphins
Dolphins practice unihemispheric sleep, with one brain hemisphere resting while the other stays alert, allowing them to surface for air and watch for predators.
Elephants
Elephants sleep about two hours a day, adapting their patterns to support social structures and their constant search for food.
Horse
Horses can sleep standing and need only two hours of deep sleep per day. This ability helps them respond swiftly to potential threats.
