Why not white shark ?

Shark constantly have to keep swimming to keep water passing over their gills.sharks need many things, including a certain shaped tank to allow for this glide pattern. For human its hard to keep this all things up

Does this also mean they don't sleep?

If I remember correctly most of their brain sleeps, just a part stays awake. Just like how horses can sleep standing up.

I know dolphins do this, they sleep half of their brain and the other half stay awake.

Juvenile sharks have to do the same? They have to keep swimming from birth?

Yes, they are hatched in the mothers womb and are active when they leave.

They do take breaks and they have been seen staying still on currents so they don't have to move.

No one knows for sure, but it's probably because Great Whites are open-ocean animals that need massive ranges. Most aquarium sharks are coastal or reef hunters that are adapted to more cramped cosmopolitan surroundings.

Thank you so much for your replies

I have never heard of anyone keeping sharks as pets. I know some people do keep the smaller species but they are very expensive to care for and require massive tanks!
