Giant Squid
Architeuthis duxDwelling in the twilight and bathypelagic zones of the open ocean, giant squids navigate total darkness using enormous dinner-plate-sized eyes that detect faint bioluminescence and the silhouettes of approaching predators. They capture prey by rapidly shooting out a pair of elongated feeding tentacles lined with hundreds of toothed suckers, dragging fish and other squids toward a powerful, parrot-like beak. Neutral buoyancy is maintained without a gas-filled swim bladder by concentrating ammonium ions throughout their muscular tissues.
