Still Waters Posted October 22, 2015 #1 Share Posted October 22, 2015 Crocodiles can sleep with one eye open, according to a study from Australia. In doing so they join a list of animals with this ability, which includes some birds, dolphins and other reptiles. Writing in the Journal of Experimental Biology, the researchers say the crocs are probably sleeping with one brain hemisphere at a time, leaving one half of the brain active and on the lookout. http://www.bbc.co.uk...onment-34572433 2 Link to comment Share on other sites More sharing options...
+Nuclear Wessel Posted October 22, 2015 #2 Share Posted October 22, 2015 That's actually really interesting. I wonder if human brains could be conditioned to use one hemisphere to sleep and the other hemisphere to remain active? 2 Link to comment Share on other sites More sharing options...
Astral Hillbilly Posted October 23, 2015 #3 Share Posted October 23, 2015 I'm not sure, but I have heard of people who sleep with both eyes open, although I've never met one. 1 Link to comment Share on other sites More sharing options...
Immune to Bieberfever Posted October 24, 2015 #4 Share Posted October 24, 2015 #nuclearwessel: yeah great but not for me when i am done after my usual 14 hour hospital workday, i just want to go totally out!

Ashyne Posted October 24, 2015 #5 Share Posted October 24, 2015 Why do crocodiles need to sleep with only one eye open "to look out for threats" when they are usually at the top or near the top of the food chain and are predators in every ecosystem?

Lots of things eat baby crocs. 1 Link to comment Share on other sites More sharing options...
Saitung Posted October 25, 2015 #7 Share Posted October 25, 2015 Old new of sorts as birds and fish also sleep with one eye or eyes open. Since avians may be descendants of reptiles, this similarity would be expected. Hey, Dinosaurs had a Hard Life. Link to comment Share on other sites More sharing options...
