This attack from an unknown specie of gigantic Octopus has been described as the source of 

various reports of seamonsters like the lusca kraken, akkorokamui, as well as the unidentified carcasses known as the globsters, like the st Augustine monster in 1896 which was washed ashore in Florida, It was initially postulated to be agigantic octopus.

in 2007 a colossal squid was accidentally caught by fishermen in Ross Sea off Antarctica. it was about ten meters long, including its tentacles, and it weighed approximately 500 kilograms! Scientists believe that this specie of squid can grow even larger than it was.

    

another similar sea monster known as the giant squid has a torpedo-shaped body, eyes that can be as large as the human head, a parrot-like beak strong enough to cut a steel cable, it has eight arms with rows of suckers, and two long tentacles that she uses for feeding it can propelled itself through the waters at 30 kilometres an hour, amazing can even launch itself into the air! this sea creatures have been sighted fewer than 50 times in the past century, and have never been studied in the wild. 

 but as large as these gigantic Octopus, collosal and giant squids however are just a meal for an even larger aquatic animal.

Two thousand miles from the nearest land from the western coast of South America. the crew of the Essex watched in horror as the enormous bull whale of headed for their mother ship. Marooned in small, open boats the 20 men stood, powerless, as the creature struck their vessel at full speed.Wood splintered, the whole structure of the ship shook. Then, after swimming off to leeward, the whale gathered its strength and camethundering towards the Essex again, even faster than before. As the crew floundered in the middle of the Pacific they knew their lives were in danger. None, though, was prepared for the appalling choices they were going to have to make in the days and weeks that followed.
