Giant Squid
Bigger than the one you eat in Fish n Chip restaurant
WELLINGTON, New Zealand -- A rare
and dangerous squid with eyes the size of dinner plates and scores of
razor-sharp hooks to snag its prey has been caught by fishermen off Antarctica,
New Zealand scientists said on Thursday.
The half-grown female colossal squid is only the second intact example of the
monster cephalopod known to have been found, said marine biologist Steve O'Shea
of New Zealand's national museum.
"I've seen 105 giant squid, but seeing something like this is pretty
sensational," O'Shea told Reuters.
A trawler caught the 150 kg, 330-pound squid in the sub-Antarctic Ross Sea about
3540 kilometers (2,200 miles) south of Wellington.
The squid was eating Patagonian Toothfish, which grow to two meters in length,
when it was caught. It was dead when it was hawled into the trawler and the
remains are now in the New Zealand national museum.
The body of the colossal squid is much bigger than the giant squid, which can
weigh up to 900 kg, 2,000 pounds when fully grown. A giant squid's tentacles can
be up to 13 meters long, compared with five meters on the recovered creature.
Comparisons are difficult because of the colossal squid's hostile environment
and rarity. Five of the six previous discoveries have only been pieces inside
sperm whale stomachs.
More dangerous
American marine biologist Kat Bolstad said the colossal squid was a more
dangerous animal than the giant squid, the mythical monster of the deep that
attacked Captain Nemo's Nautilus in Jules Verne's "Twenty Thousand Leagues Under
the Sea."
"This is a very aggressive animal and moves quickly. If you fell in the water
next to it you would be in big trouble," said Bolstad.
The colossal squid finds food by literally glowing in the dark, deep waters to
light up prey for its massive eyes -- the biggest of any animal.
But it is the colossal squid's weaponry that marks it out from its giant cousin.
Its eight arms and two tentacles have up to 25 teeth-like hooks -- deeply rooted
into muscle and able to rotate 360 degrees -- as well as the usual suckers to
ensure fish do not escape.
The hooks not only hold fish for the squid's two parrot-like beaks, but also are
used to fend off attacks from hungry sperm whales, O'Shea said.
The species, whose scientific name is mesonychoteuthis hamiltoni, was previously
thought to have lurked at least 800 meters down in the freezing waters near
Antarctica, but the specimen found a fortnight ago was near the surface.
O'Shea said the discovery raised questions about what else was down deep in the
ocean.
"We know so little about the marine environment in general. If animals like this
are turning up, what's going to be at 3,000-meters (10,000-foot) depth. We don't
know," O'Shea said.
