Rare giant squid sighting in Japanese harbour

A giant squid provided a rare treat for onlookers in Toyama Bay when one swam into the harbour.

The 3.7m (12ft) cephalopod was much smaller than the 13m they can grow to.

It spent several hours in the harbour on Christmas Eve and was filmed by local divers.

Professional underwater cameraman Takayoshi Kojima told the BBC he rushed to the harbour when a marina manager called and he helped guide the squid to the exit to the sea, where it finally disappeared.
