Calamari Anyone?
small but... writes "A six-meter long specimen of a species of squid [Mesonychoteuthis hamiltoni] previously only known by the stomach contents of sperm whales has been caught by a fishing vessel in Antarctic waters, and brought to the national museum of New Zealand. It has a huge beak, sharp swivelling hooks on its suckers, and is believed to be a juvenile. Adults of the species are thought to grow to as long as twelve meters. No reports indicate the presence of lasers; or, for that matter, anything I would consider a forehead."
That's 2m in MANTLE length, the mantle being, apparently, the muscle that surrounds the squid's body. That is, I believe, not including the length of the tentacles which is what they are discussing, and which are apparently 6m long in this specimen.
