Krakens are enormous apex predators of Clavimaria.
Krakens are octopodes of unmatched proportions; with their arms stretched, they can reach a diameter of 100 metres. Unlike most pulpines, krakens have 12 arms. They have a pair of eyes on their large head, as well as a razor-sharp beak fortified with metal.
A kraken's siphon is proportionally large, as the weight of the animal increases cubically with length. They can pump dozens of litres a second, and are used even while it is crawling on the sea floor.
Normally, an animal this huge wouldn't be able to maintain a stable metabolism and survive. The kraken, however, has many symbiotic cornalgae growing on it and providing it sugar. As such, it is essentially a mixotrophe. Besides the algal growths, its skin can change colour in order to camouflage.
As do most octopodes, the kraken actually spend most of their time crawling on the sea floor, rather than swimming. This saves energy. While there, it will feed on giant crabs and other loligans, besides carcasses. It will often lift itself to hunt large whales, grandostiines and wyrms.
The kraken is feared by sailors and is known to destroy ships. This has been questioned by naturalists, as it seems pointless to attack boats and such vessels, since octopodes can't eat wood or metal. They are also smart animals, so they wouldn't be attacking the ships by accident. Actually, however, males sink ships to make nests for their mates, which are attracted to elaborate dens.
In nature, krakens harvest giant boatfish as prey. These are not as large or durable as some artificial ships, however, which are preferred.
