GENERAL KNOWLEDGE

Detailed explanation-1: -Sharks do not sleep like humans do, but instead have active and restful periods.

Detailed explanation-2: -Sharks do not experience sleep the same way humans do. Some can’t sleep at all, and the ones that do never close their eyes. Some shark species do, however, cycle through alternating periods of alert wakefulness and profound rest that is similar to sleep.

Detailed explanation-3: -In the wild and aquariums, some sharks that breathe using buccal pumping are often seen lying still on the sand during the day and actively swimming around at night.

Detailed explanation-4: -Shark species that need to swim constantly to keep water moving over their gills seem to have active periods and restful periods, rather than undergoing deep sleep as we do. They seem to be “sleep swimming, ‘’ with parts of their brain being less active, or “resting, ‘’ while the shark remains swimming.
