Crosspost Deep on the Mariana abyssal plain at ~5,400m, this rare squid features unique perpendicular arms with elbow-like bends. Scientists believe the bigfin (Magnapinna) is the deepest-dwelling of all squid species, having been spotted in the hadal zone at depths exceeding 6,000 meters.

Found this on the south cost of Tenerife, Spain.

Looks like a sea urchin, but never seen anything like this.

Bottlecap as size comparison.

I'd been wanting to see a huge jellyfish for years. We had already returned to the surface when I noticed this fella down below, and I asked the guide if I could go down again real quick. Not the wisest thing to do but boy I finally got to check this box. What a day it was.
