Interesting, but the bottlenose dolphin has the cleverest system of sleeping.

The problem a whale has if it sleeps how does it surface to breath
It sleeps by shutting down half of its brain at any one time
So one half is asleep and the other half deals with the lbreathing / surfacing bit
Than that half wakes up and the other half goes to sleep
MOD: Some pointless sniping removed.

I'd have said just like a remoaner, but they would die with no brain function.

Saw a dead pike washed up on the beach today, not something you see that often.
They sleep with one half of their brain active, one eye closed, then swap sides. The sleeping half, just dozes. They also usually sleep in pairs to look after each other.
I guess if such mammals ever went fully to sleep, as we do, then they would drown. They have to surface regularly to take a breath.
Our sleep is deeper, but the depth of sleep varies during the night. We still have to continue to breath, heart has to beat, we stay alert to noises and disturbance.
Not heard that one in a while! They lie down to sleep, the idea of a horse standing there wide eyed at night is just scary.

"Not only can your horse sleep with his eyes open, but he can also sleep standing up; in fact, most of his sleeping time is done this way. He has a handy mechanism in his legs called a “stay apparatus,” allowing him to relax his muscles while keeping his legs locked in position to hold him up. He also takes advantage of this when relaxing after a hard workout, to give his tired muscles a break. If your horse is standing with his eyes open, look at his lower lip and hind feet: If his bottom lip is relaxed and drooping, and he has one hind foot cocked, or resting on its toe, he is sleeping or dozing." https://animals.mom.me/horses-close-eyes-sleep-3772.html
They do lie down, but not always. Makes sense really - if you are 50% steak you want to be able to wake and run fast if a predator arrives.

Honestly I grew up with a "horsey" family and now live near lots of farmers who rent out fields for horses, not once have I see a horse having a kip, while standing up and with its eyes open. Far more common to see one flat out on the stable floor with the barn cat somewhere nearby! Granted you do see a stubborn one at the County Show with its head dropped and eyes shut, but that's probably the short bursts of sleep/dozing that your quote refers to.
Meercats on the other hand... seeing them huddled together under a heat lamp in a circle; they look like they belong in the smoking shelter at a JD Wetherspoons.
