Magnapinna sp. - The Long-armed Squid

From National Geographic:
"In a few seconds of jerky camerawork, the squid appears with its huge fins waving like elephant ears and its remarkable arms and tentacles trailing from elbow-like appendages.

Despite the squid's apparent unflappability on camera, Magnapinna, or "big fin," squid remain largely a mystery to science.
ROVs have filmed Magnapinna squid a dozen or so times in the Gulf and the Pacific, Atlantic, and Indian Oceans."
