7, 2005—Science never sleeps, even when facing down a hurricane. Luckily for
a handful of deep sea explorers, they've found a rather unusual nightlight.
This still photo from a video taken on August 22 shows the first visual evidence of the fluorescent chain catshark. Scientists taking part in the National Oceanic and Atmospheric Administration's Operation Deep Scope 2005 expedition found the three-foot-long (one-meter-long) animal on the sea floor of the Gulf of Mexico.
The fluorescent shark was initially observed—though not captured on film—during last year's Deep Scope expedition. Starstruck researchers noted that the glowing menace bears an uncanny resemblance to the fictional jaguar shark pursued by Bill Murray in the 2004 movie The Life Aquatic with Steve Zissou.
Deep Scope 2005 researchers found this shark only days before Hurricane Katrina moved over the Gulf of Mexico on August 27. At its peak, Katrina was listed as a Category Five storm, with winds reaching 175 miles an hour (280 kilometers an hour). The expedition ship waited out the storm at a Texas port while research continued onboard.

Like something straight out of a Jules Verne novel, an enormous tentacled creature looms out of the inky blackness of the deep Pacific waters.
But this isn't science fiction. A set of extraordinary images captured by Japanese scientists marks the first-ever record of a live giant squid (Architeuthis) in the wild.
The animal—which measures roughly 25 feet (8 meters) long—was photographed 2,950 feet (900 meters) beneath the North Pacific Ocean. Japanese scientists attracted the squid toward cameras attached to a baited fishing line.
The scientists say they snapped more than 500 images of the massive cephalopod before it broke free after snagging itself on a hook. They also recovered one of the giant squid's two longest tentacles, which severed during its struggle.
The photo sequence, taken off Japan's Ogasawara Islands in September 2004, shows the squid homing in on the baited line and enveloping it in "a ball of tentacles."
Tsunemi Kubodera of the National Science Museum in Tokyo and Kyoichi Mori of the Ogasawara Whale Watching Association report their observations this week in the journal Proceedings of the Royal Society B.
"Architeuthis appears to be a much more active predator than previously suspected, using its elongated feeding tentacles to strike and tangle prey," the researchers write.
They add that the squid was found feeding at depths where no light penetrates even during the day.
