Predator spine vs claws

With vastly concentrated strength, its spur still snagged deep in the human flesh, the alien punctured the skin at the base of Hawkins’s spine with its other clawlike hand, severing the cord like a knife through butter. Then it bore upward, ripping at the vertebrae. Stubbornly it yanked harder, pulling the entire spine free of the body, a sickly snapping and popping of cartilege echoing off the chamber walls as bone separated from tissue.

Without a trace of emotion the alien bore the head and spine into a further chamber of the ship, leaving a ghostly trail of blood and flesh on the pristine floor.
