Today I learned that cuttlefish experience REM sleep, and that it makes their skin flash random colors. This is the cutest thing ever.
The electric eel at my aquarium has a voltmeter attached to his tank, and whenever he pumps out a burst of electricity–either when he’s navigating his tank or getting fed–the meter lights up and makes noise. Sometimes, I’ll walk past him when he’s snuggled up and totally motionless on his log, and see the voltmeter going crazy.
I am left to assume that he is dreaming, and is sleep-zapping at the things in his dreams.
I am absolutely delighted to learn that electric eels dream of kicking ass.
