As a firm believer in empirical study I took some fish fingers out of the freezer and sang them a lullaby.....they are still asleep !!


Actually Tony, here's some text which I have yet again blatantly copied and pasted from somewhere else....which is nice !!

Most all fish spend time in an energy-saving state that can be called
"rest", and we might even call their behavior "sleep", though it is probably
different than "sleep" in most land
animals.  Many fish, like Bass and perch, rest on or under logs at
night.  Coral reef fish active in the day, hide and rest in crevices
and cracks in the reef to avoid being eaten at night.
The resting behavior of fish is very different from their behavior the
rest of the day. Many minnows, for example, which are very active in
schools during the day, scatter and remain motionless in shallow
water at night.  Many fish "rest" or "sleep" during the day and are
active at night instead, but almost all fish sleep.
There are some animals that never stop swimming, like many species of
shark, however, they HAVE to keep moving to push water through their mouths
in order to breathe, and they may still sleep while moving,we just don't know yet.


Hope this helps young man !!

Men are the same as women, just inside out !

OK I know whales and dolphins are mammals, not fish, but you may be interested to know that..

" Whales and dolphins don't sleep like us. They rest at the water surface or take little naps while swimming. The two halves of their brain are alternatively put to sleep. One half of the brain remains always active in order to allow the animal to breathe."
