ATTACK OF THE ANOTHER WEEK OF TWITTER #WEIRDSCIFACTS!!!
690. Feb 01: Atolla wyvillei, the deep-sea jelly that use bioluminescence to “scream” for help when attacked! Bioluminescence is used in many different ways in the ocean, but the most unusual is perhaps this jelly’s strategy! When attacked, it flashes frantically, hoping to draw a predator that will eat its attacker.
691. Feb 02: Case of hypothermic man, 2 hours in cardiac arrest, resuscitated, no neuro deficits. We are used to the idea that a person has minutes, at most, to live when their heart stops. When “preserved” at low temperature, however, people can survive extended periods with no circulation, and still come out with no lasting neurological damage. (h/t @msbellows)
694. Feb 05: Many owls have asymmetric ear size & placement, allowing better prey location. (This fact was posted in honor of #SuperbOwlFacts!)
