"Octosquid" discovered off Hawaiian coast

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.
