Fish don't sleep like humans do, they don’t close their eyes or lie down. Instead, they rest by slowing down their movements and breathing less. They stay in one place near the bottom of the ocean or a quiet part of the water where it's safe to be still. Even though they're underwater, they don’t drown because they’re already used to living there, just like we’re used to being on land.
Examples
- A goldfish might float near the top of a bowl and barely move when it's resting.
- A sea horse might sway slowly back and forth while sleeping near coral.
- A clownfish might hide among anemones and stay still for hours.
