    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.

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

  • 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.
