Re:8 Meters? Depends how you measure. (Score 1)

Turns out there is more than one way to measuer a squid :P

Mantle length (as opposed to total length) is the standard measure in cephalopods. Architeuthis is not known to attain a mantle length in excess of 2.25 m. Standard Length (SL) is the length of a squid excluding the tentacles; in Architeuthis this measure very rarely exceeds 5 m.
