An expert in squid, Steve O'Shea, has seen about 105 giant ones. But he described this colossal squid as "pretty sensational".
It weighs 150kg (330lb) but when they are fully-grown, they are bigger than a double decker bus. Since this one was only a teenager in squid terms, comparisons between body size are hard.
But colossal squid bodies and tentacles are much, much bigger than those belonging to a giant squid.
