"When this animal was alive, it really has to be one of the most frightening predators out there. It's without parallel in the oceans," Dr O'Shea said.
The specimen, which was caught in the past few weeks in the Ross Sea, has a mantle length of 2.5 metres. That is a larger mantle than any giant squid that Dr O'Shea has seen and this specimen is still immature, the NZ scientist believes.
"It's only half to two-thirds grown, so it grows up to four metres in mantle length." By comparison, the mantle of the giant squid, Architeuthis dux, is not known to attain more than 2.25 metres.
