Basedd on my experienes in Eleuthera, Bahamas, nurse sharks actually do nap, breathing regularly and without moving, which most shaks cannot do; they have to be moving to get enough water through their gills. Nurses can breathe stationary because they can pum water through their mouth and out their gills. Nurse sharks generally dont have a sleep period like we do, they dont have a long period of REM sleep, which is when you are in a deep sleep state. Nurse sharks generally nap for around an average of 1 hour, but sometimes 2, and 3 hours as well. Nurse sharks will nap either on the sea floor (in my case, in a small bay area, 20 feet deep) or in their shallow nests. Nurse sharks are generally nocturnal animals, which is why the often nap in the day.
Some asleep on the seabed, while others continue to swim while asleep.
Sometimes, Nurse sharks are called giant sleepy sharks. Sometimes, Nurse sharks are called giant sleepy sharks.

The sharks that have barbels are generally nurse sharks and sharks that stay near the bottom of coral reefs as they are filter feeders and use them to scoop in plankton.

Most sharks do not sleep.If they stop swimming....they will die.They need water running through their gills to get oxygen.However.....some sharks, like the Nurse Shark, can stop swimming for a while & have a snooze.

Nurse Sharks (Ginglymostoma cirratum) are known to weigh as much as 330 lbs(150 kg) or more for the largest wild caught specimens. It's possible for some captive Nurse sharks to exceed that - if they are overfed.
