If you thought those submersible videos of swordfish and sperm whales were something special, here's something right out of The Abyss.
A remotely operated underwater vehicle caught this creature floating around in the brine — commenters on YouTube are positing that it's a specimen of the Deepstaria enigmatica jellyfish, whereas other folks on Reddit are suggesting it's errant whale placenta. Any marine biologists care to chime in? (UPDATE 5/9/12: Definitely Deepstaria enigmatica.)
BONUS #1: A two-meter-long Magnapinna sp. deepwater squid off of the Gulf of Mexico. Thanks, Sigge!
BONUS #2: The real-life Abyss in North Carolina.
BONUS #3: The blanket octopus, a hilarious creature in its own right.
