00:20But do you know how many animals sleep?
00:24Especially the animals in the water, such as fish,
00:27whether they sleep or not,
00:29and if they do, how do they sleep?
00:31Do you want to know the answer?
00:33Now, I'm going to tell you the answer.
00:37Normally, humans' sleep is just the sound of the wind.
00:42But for fish, there is no sound of the wind at all.

00:55In fact, it's not different from humans.
00:57When fish sleep, they sleep on the edge of a rock in that area.
01:02It's the continuation of their sleep, but in a longer period of time.
01:06Or they don't sleep all the time,
01:08and their belly starts to get bigger.
01:11Some fish like to sleep in the river,
01:13and some fish like to sleep in the lake.
01:15Until now, there may be many people who say
01:18that fish know when to sleep and how to sleep.
01:21Fish also know when to rest in their lives like us.
01:25Those who have seen fish in the river can notice and see
01:28that when we turn off the light at night,
01:30the fish will be active and sleep together.
01:33When the sun rises, we turn on the light again.
01:35The fish will be active and go to sleep normally.
01:38But some fish like to turn off the light at night and sleep together.
