Anura Posted January 6, 2011 Share Posted January 6, 2011 (edited) Fish breath by taking in water threw thier mouths and out thier gills. So if fish stop moving do the stop breathing. Or do they sleep in a current. And if fish did sleep in a current wouldn't that current push them along, canselling out thier movment. Or do they just not sleep?

Ringer Posted January 6, 2011 Share Posted January 6, 2011 They sleep, in fact studying zebra fish sleeping is helping neuroscientists find what sleeping is for. http://www.scientificamerican.com/article.cfm?id=why-sleep-is-good-for-you Link to comment Share on other sites More sharing options...
Anura Posted January 6, 2011 Author Share Posted January 6, 2011 They sleep, in fact studying zebra fish sleeping is helping neuroscientists find what sleeping is for. http://www.scientifi...is-good-for-you That brings up a second question. How is it they dont suffocate? Do they keep moving while asleep? Link to comment Share on other sites More sharing options...

alpha2cen Posted January 7, 2011 Share Posted January 7, 2011 In the case of dolphin, it is more difficult, they have to do aerial respiration during the sleep. Their brain is divided into two parts. When they sleep, one part of brain is sleeping and the other part of brain is awakened. 1 Link to comment Share on other sites More sharing options...
Moontanman Posted January 7, 2011 Share Posted January 7, 2011 That brings up a second question. How is it they dont suffocate? Do they keep moving while asleep? Do you suffocate when you sleep? Fish continue to breath just like we do when they sleep. Most fish can and do pump water through their gills even when swimming. Link to comment Share on other sites More sharing options...
Ahsan Iqbal Posted January 10, 2011 Share Posted January 10, 2011 isn't there any clear answer available to the question. After reading all the posts, I didn't even come to know that the fish sleep or not? Please can anyone provide a clear answer/ Link to comment Share on other sites More sharing options...
