Which animals sleep and which don't?

If I'm not mistaken, all mammals and birds sleep but fish don't sleep. What about reptiles? amphibians? insects?

I am not sure but I think all animals go through some sort of sleep cycle.

All animals sleep even though not all of them close their eyes when doing so. Only fish might not sleep - it is not clear yet to biologists. Dolphins sleep when half of their brain is awaken, because their breathing process depends on their brain. Cows may sleep while standing (but can't dream while sleeping that way).

all mammals/fish/birds/rodents sleep , some sleep differently or less than us but for sure all do sleep, for example cows sleep with eyes open, hippos sleep underwater, bats sleep upside down, migratory birds sleep while flying over oceons, some animals sleep while standing up, but even they have to lay down for atleast a few min daily.
