Carnivorous. The vampire squid has the lowest mass-specific metabolic rate of any cephalopod because of its decreased reliance on locomotion for escaping predators and capturing prey in the light-limited deep sea. The vampire squid uses its sensory filaments to find food in the deep sea and also has a highly developed statocyst indicating that it descends slowly and balances in the water almost effortlessly. Despite its name and reputation, Vampyroteuthis infernalis is not an agressive predator. While drifting, the squid deploys one filament at a time until one of them contacts an animal of prey. The squid then swims around in a circle hoping to catch the prey.
