That's pretty amazing that crocodiles can sleep with ONE eye open!

i didnt know this :)

yo that is so swag

this is a boring topic

that pretty cool

crepy and cool at the came time

is that even possible for someone or something to do that i mean how can you be half asleep and awake i mean its highly impossible for a living creature to do that its not possible how does the brain handle that you absolutely cant be asleep and awake at the same time but if it was possible that would be pretty cool like you could sleep and be on the look out at the same time

cool

wow

cool
