Colossal squid out of the freezer New Zealand squid thaw put on ice
(about 2 hours later)
The biggest colossal squid ever landed comes out of the deep freeze over the next day and a half in New Zealand. Technicians in New Zealand have postponed until Monday the delicate process of defrosting a colossal squid caught in Antarctic waters last year.
The Mesonychoteuthis hamiltoni specimen, caught in February last year in Antarctic waters, is 10m (33ft) long and weighs over half a tonne. Having removed the creature from the freezer on Sunday, the team realised it would defrost too early for a planned examination by scientists on Wednesday.
The riddle for technicians at the Museum of New Zealand Te Papa centre has been how to thaw the squid without any parts of its body starting to rot. The half-tonne 10m-long squid is now back in the freezer, still wrapped in the fishing net in which it was caught.
The thawing and subsequent dissection will feature in a live webcast. The eventual thawing and dissection will feature in a live webcast.
The procedure began on Sunday in Wellington. The Mesonychoteuthis hamiltoni specimen was caught in February 2007 in Antarctic waters.
"We estimate it will take about 36 hours to fully defrost," said Chris Paulin, projects and compliance manager at the Te Papa centre.

Interest in the dissection from the wider scientific community, never mind the public, is likely to be huge. The riddle for technicians at the Museum of New Zealand Te Papa centre has been how to thaw the squid without any parts of its body starting to rot.
The colossal squid grows heavier and probably longer than the giant squid
The colossal squid is remarkable for its size, but also for how rarely it has been sighted.The colossal squid is remarkable for its size, but also for how rarely it has been sighted.
It was identified first in 1925 from two tentacles found in a sperm whale's stomach.

Very little is known about how and where they live. The one certainty is that they are fearsome opponents, with big beaks and unique swivelling hooks on the club-like ends of their tentacles.Very little is known about how and where they live.

The specimen has been frozen in a fishing net inside a plastic big container. Later in the week, scientists are expected to give public lectures about their initial results.

"We have to remove the container around it, manoeuvre the frozen squid into the defrosting tank, then carefully remove the net as it defrosts," said Carol Diebel, Te Papa's natural environment director.
"It's a very delicate procedure."
Later in the week, scientists will give public lectures about their initial results.
Once thawed and examined, the squid will be embalmed and preserved.Once thawed and examined, the squid will be embalmed and preserved.
