Curious creature caught off Keahole Point
The animal, dubbed an "octosquid," is found off the Big Isle

It's a squid, it's an octopus, it's...a mystery from the deep.

What appears to be a half-squid, half-octopus specimen found off Keahole Point on the Big Island remains unidentified today and could possibly be a new species, said local biologists.

The specimen was found caught in a filter in one of Natural Energy Laboratory of Hawaii Authority's deep-sea water pipelines last week. The pipeline, which runs 3,000 feet deep, sucks up cold, deep-sea water for the tenants of the natural energy lab.

"When we first saw it, I was really delighted because it was new and alive," said Jan War, operations manager at NELHA. "I've never seen anything like that."

The natural energy lab is a state agency that operates Hawaii Ocean Science and Technology Park in Kailua-Kona, adjacent to one of the steepest offshore slopes in the Hawaiian Islands.

According to Richard Young, an oceanography professor at the University of Hawaii at Manoa, the specimen tentatively belongs to the genus Mastigoteuthis, but the species is undetermined.

War, who termed the specimen "octosquid" for the way it looked, said it was about a foot long, with white suction cups, eight tentacles and an octopus head with a squidlike mantle.

The octosquid was pulled to the surface, along with three rattail fish and half a dozen satellite jellyfish, and stayed alive for three days. According to War, the lab usually checks its filters once a month, but this time, it put a plankton net in one of the filters and checked it two weeks later.

The pitch-black conditions at 3,000 feet below sea level are unfamiliar to most but riveting to scientists who have had the opportunity to submerge. The sea floor is full of loose sediment, big boulders and rocks, and a lot of mucuslike things floating in the water, which are usually specimens that died at the surface and drifted to the bottom.

"It's quite fascinating," War said. "When you get below 700 feet, it's a totally different world. Lots of fish have heads like a fish and a body like an eel. There are fish floating in a vertical position, with the head up, and don't move unless they're disturbed."

Christopher Kelley, program biologist for the Hawaii Undersea Research Laboratory, went to the natural energy lab Tuesday to pick up the preserved octosquid, rattail fish and jellyfish, which had been stored in a freezer, and brought them back to UH-Manoa's oceanography department.

"It's a beautiful squid. It's a gorgeous ruby red color," Kelley said. "We really enjoy these little mysteries that come up."

Also during Kelley's visit to NELHA yesterday, he and War talked about a more formal sampling program to search for other deep-sea critters. War said their goal is to sample the intake screen more often and capture animals alive and study them in captivity.

"This opens up a whole new area of research that UH can be involved with," War said.

In October, NELHA will be checking its deep-sea pipelines, something that usually happens every eight to 10 years, because it is worried that something might have happened to them during the earthquakes in October.

"If it's a new species, (NELHA) would like to name it," War said. "But that is sort of the honor of whoever classifies it."

Very interesting......it will be nice when they release some video footage.

This octosquid story hit the news last month. But I only just realized that nobody posted it here. Associate Press since had an update. Excerpt:

”The creature appeared to be half-squid, half-octopus because it was missing its two tentacles and had only its eight arms…But an analysis by University of Hawaii experts revealed the creature to be a little-known squid species that scientists are aware of but have yet to name.”

Still very cool, thanks for posting it!

...and deep sea diving expeditions, and new species, here's one that National Geogrpahic listed on their "Suprising Sea Animals Discovered in 2006" (Photograph by Ifremer/A. Fifis ©2006, Courtesy of the Census of Marine Life):

And if you think this furry crab looks amazing, wait till you read the Nat Geo news (that follows) which says its hairy arms support colonies of yellow bacteria that it may be deliberately cultivating for either food or sensors.

The "yeti crab," discovered on the floor of the Pacific Ocean, is so extraordinary that a new taxonomic family had to be invented for it.

The new species was found during a deep-sea dive expedition, some 900 miles (1,500 kilometers) off Easter Island.

Living next to hydrothermal vents at depths of 7,540 feet (2,300 meters), the blind white crustacean, named Kiwa hirsute, was also dubbed the yeti (or abominable snowman) crab because of its hairy arms, which support colonies of yellow bacteria.

Led by the Monterey Bay Aquarium Research Institute in California, the dive team speculates that the animal may deliberately cultivate these bacteria for food or as tiny sensors that help the crab find food or a mate.

Other researchers suggest the crustacean could use the bacteria to combat toxic fluids that rise from the volcanic vents.

Mineral-eating bacteria thrive on deposits from the vents, says Chris German of the Southampton Oceanography Centre in England. "Show them a metal sulfide deposit on the seafloor and they think it's a six-course banquet," he joked.

"If you've got things that want to [eat toxic fluids], why not carry a bunch of them around with you if you're working in a hazardous environment," German added. "They could be your natural safeguards."
