This is a video captured off the coast of Sanriku, Japan at a depth of 5,350-meters (~3.3 miles) of a Subspinctoria cinerea. What the hell is a Subspinctoria cinerea? You're looking at it. It appears to be half shrimp, half fairy, and 100% from the Lost City Of Atlantis. Now we just need to follow it back to Atlantis and steal all of their advanced technology. You think they've got x-ray glasses? I bet they've got x-ray glasses, and I call dibs on them. Plus a potion that lets you breathe underwater. "It's called scuba gear." Please, mermaids don't go after guys using scuba gear.
Keep going for the video.
Thanks to Marc B, who's convinced Tinkerbell banged a shrimp and this is their lovechild.
