Does horse sit and fishes do sleep and yes then how ?
Answers
fish are no different. But how water-dwellers snooze can look really different from the way humans get their zzz's. Some differences are obvious (for instance, they don’t lie down or close their eyelids, since sharks are the only fish that even have them and only close them to protect their eyes during encounters with other animals), while others are not-so-obvious (fish never go into REM sleep and some, like sharks, have to keep swimming while they snooze, because they need constant ventilation of their gills). But no matter what state sleep takes, the general idea is the same: It's a period when activity and metabolism slow way down as a way to conserve energy and restore the body.
horses cannot sit and sleep by standing whereas fishes never sleep
