They mainly consume mollusks and crustaceans. They are also known to eat various types of fish and snails. Nearly all octopuses are predatory; bottom-dwelling octopuses eat mainly crustaceans, polychaete worms, and other molluscs such as whelks and clams; open-ocean octopuses eat mainly prawns, fish and other cephalopods. Other octopus species live in deep, dark waters, and rise from below at dawn and dusk to search for food. They perform their famous backward swim by blasting water through a muscular tube on their body called a siphon. They also crawl along the ocean's floor, tucking their arms into small openings to search for food. Giant Pacific octopuses can consume 2–4% and gain 1–2% of their body weight each day. Three defensive mechanisms are typical of octopuses: ink sacs, camouflage, and autotomising limbs. Most octopuses can eject a thick blackish ink in a large cloud to aid in escaping from predators. They also have specialized skin cells, called chromatophores, for both color changing and light reflection and refraction.
