Krakens were aquatic monsters that could be compared to octopus or squid but gigantic in size. They could have sometimes been mistaken for islands. Stories have claimed that the tentacles could be longer than a mile. Its eyes are the size of dinner plates. Kraken mainly ate fish. They would draw fish by releasing their feces which smelled strongly and were thick. Once there were multiple fish near them, Krakens would devour them.
