1.5 miles down, submersible films huge squid with "elbows"

National Geographic has the astounding video.

A mile and a half (two and a half kilometers) underwater, a remote control submersible's camera has captured an eerie surprise: an alien-like, long-armed, and—strangest of all—"elbowed" Magnapinna squid...

...The clip — from a Shell oil company ROV (remotely operated vehicle) —arrived after a long, circuitous trip through oil-industry in-boxes and other email accounts.

"Perdido ROV Visitor, What Is It?" the email's subject line read—Perdido being the name of a Shell-owned drilling site. Located about 200 miles (320 kilometers) off Houston, Texas (Gulf of Mexico map), Perdido is one of the world's deepest oil and gas developments...

...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...

Another positive development related to energy exploration, eh?
