There is no definitive answer on how long giant squid can get. We know that the giant squid can get up to 43 feet (13 meters) long with some predictions measuring up to 66 feet (20 meters) long.
This squid was spotted in Toyama Bay in Japan and is considered small for a giant squid and is estimated to be around 12.1 feet (3.7 meters) long, and possibly a juvenile.
