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.
In a brief video from the dive recently obtained by National Geographic News, one of the rarely seen squid loiters above the seafloor in the Gulf of Mexico on November 11, 2007.
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.
The video clip shows the screen of the ROV's guidance monitor framed with pulsing inputs of time and positioning data.
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.
The recent video marks the first sighting of a
Magnapinna at an oil development, though experts don't think the squid's presence there has any special scientific significance.
But the video is evidence of how, as oil- and gas-industry ROVs dive deeper and stay down longer, they are yielding valuable footage of deep-sea animals.
Some marine biologists have even formed formal partnerships with oil companies, allowing scientists to share camera time on the corporate ROVs—though critics worry about possible conflicts of interest.
