Episode notes
Unihemispheric Sleep Keeps Animals Vigilant
- Some animals use unihemispheric sleep to stay alert while resting.
- Dolphins and some birds sleep with one brain hemisphere active so they can surface or glide while dozing.
Lions Rest Daylong To Save Energy For Night Hunts
- Lions are largely crepuscular, active at dawn and dusk, and spend much of the day resting to conserve energy for hunting.
- A Serengeti pride shelters in copies and shade, grooming and napping until twilight hunting begins.
Yukon Wolves Curl Up Under The Northern Lights
- A Yukon wolf pack patrols under the aurora borealis, howling then returning empty-handed to curl up and share warmth at dawn.
- They snuggle near pine bases, curling into balls to conserve heat with rhythmic breaths as snow falls.
