|Behind the Scenes|
The Octalus is a massive multi-tentacled monster that resembles an octopus. One such creature attacked the cruise ship Argonautica.
The ship had become infested by, what the passengers thought, creatures that resembled giant worms that swallowed and digested their prey alive. Some have speculated that they are members of the Ottoia family of deep-sea archaeopriapulida worms, which have evolved to immense size in the extreme depths of oceanic trenches. In truth it was a singular creature that used its many tentacles to digest the crew while it nested within the center of the ship where it spat out the skeletal remains.
The monster's many tentacles were capable of splitting open and devouring a full grown human, where they were digested with acids and spat out. The creature was quite intelligent and was able to herd its prey into traps and dead ends. It resides in the depths of the sea and rarely surfaces. The film's prologue indicates that ships from every era have mysteriously disappeared into the South China sea, and that the creature is responsible. It has never been seen by man, until now.
