How many hours of sleep a night do mermaids need?
I heard from a friend that its eight hours a day, but they sleep like dolphins, half awake half asleep.
They can split it up like 4 hours of full asleep, or like 3 hours of full sleep and 2 of half sleep
As many as they want but they also sleep like sharks: eyes open monitoring movement, and mouth against a stream of water in a catatonic state.
oof, im part mermaid and usually get less, like 3 or 4, but I'm tired a lot so it would make sense if it's more
They can sleep in multiple short periods of time, like my cats. Not like humans who need uninterrupted sleep.
I wouldn't think many, since they probably don't exist.
Why do you think they don't exist?
5, i think they’d lie on the surface like sunfish with one eye open for any surface or water dwelling foes. maybe if a pack of them manage to capsize a fairly large boat they can have a hibernation session after gorging on all the sailor filet.
I agree, I imagine them doing a semi sleep. Like one side of the brain is asleep but the other side is awake so they can be aware of any dangers
