Fishermen land colossal squid

New Zealand fisherman have caught what is expected to be a world-record-breaking colossal squid.

The squid, 10m long and weighing about 450kg, took two hours to land in Antarctic waters, reports the BBC. It is believed to be the first adult colossal squid landed intact. One expert said calamari rings made from it would be like tractor tyres.

"I can assure you that this is going to draw phenomenal interest. It is truly amazing," Steve O'Shea from Auckland's University of Technology told local media.

Colossal squid, found deep in Antarctic waters, are thought to be about the same length as giant squid but are much heavier. The species was first identified in 1925, but very few specimens have been found.

Fisheries Minister Jim Anderton said the fishermen had been fishing for Patagonian toothfish in deep Antarctic waters when the squid - which was eating a toothfish - was caught.

"The squid was almost dead when it reached the surface, and the careful work of the crew was paramount in getting this specimen aboard in good condition," he said.

The squid was frozen in the ship's hull and brought back to New Zealand for scientific examination.

"The colossal squid has just arrived in New Zealand and it is likely that it is the first intact adult male colossal squid to ever be successfully landed," Mr Anderton said.
