Colossal Squid (Widescreen)

Known by ancient seafarers as the Kraken, the Colossal Squid has fascinated scientists and dominated the nightmares of sailors for generations. With no known limit to how large these mighty sea creatures can grow, the super squid is one of the world's greatest enigmas.

Incredibly we've caught one and stored it on ice at New Zealand's national museum, Te Papa Tongarewa. Join us as a team of specialists prepares to undertake the first scientific investigation of an adult Colossal Squid.
