What's the largest recorded squid?
Colossal squid
Based on capture depths of a few specimens, and beaks found in sperm whale stomachs, the adult colossal squid ranges at least to a depth of 2.2km (7,200ft), and juveniles can go as deep as 1km (3,300ft). It is believed to be sexually dimorphic, with mature females generally being much larger than mature males, as is common in many species of invertebrates.
