Octopod

An Octopod was an organic construct that served as a weapon of the Rutan Host.

In 1918, one such creature had its ship crash landed on the planet Earth where it remained in the oceans of the Bermuda Triangle. In that time, it attacked the USS Cyclops where it was confused by the Human crew to be a giant squid. At the time, the Doctor and Heather McCrimmon had used the TARDIS to travel to that period where they discovered the true reason why the Cyclops had sunk. They manage to temporarily stop it by throwing manganese ore on it from the cargo bay which disrupted the Octopods magnetic field forcing it back into the sea. The temporary distraction allowed them to escape and the Doctor revealed that he could not save the ship as it was part of history and thus its destruction would remain to mankind a mystery.

 * The fate of the creature remains unknown, its possible it still exists beneath the oceans on the planet continuing its directive.
