A kraken can traverse water. It in amphibious. It has an animal body. It has no hands. A kraken is a carnivore.
Out from the water a long sinuous tentacle had crawled; it was pale-green and luminous and wet. Its fingered end had hold of Frodo's foot, and was dragging him into the water. Sam on his knees was now slashing at it with a knife. The arm let go of Frodo, and Sam pulled him away, crying out for help. Twenty other arms came rippling out. The dark water boiled, and there was a hideous stench.
