cephalopod mollusk having no shell, eight muscular arms or tentacles, a pouch-shaped body, and two large, highly developed eyes.
Octopus
Mollusk. The common octopus is a master of camouflage, changing shape and color at will. Octopuses often match their surroundings to the point of becoming invisible while motionless.
Octopuses are characterized by their eight arms (not tentacles), usually bearing suction cups. These arms are a type of muscular hydrostat.
Octopuses also have a sac that contains an inky substance. When an octopus senses danger, it ejects some "ink". The ink darkens the water, thereby screening the octopus from the other animal.
Octopus vulgaris
The Common Octopus reaches 24 - 36 inches in length. The arms are lined with suckers. The skin is smooth and has special pigment cells that make it possible for the octopus to blend in with the surroundings.

Species Information
Exhibit Name and Location ...
Octopus vulgaris is one of the most common octopus species commercially fished for food and for the aquarium trade. Between 10,000 and 20,000 metric tons are caught by commercial fisheries yearly using unbaited octopus pots.
Octopus have no shell at all, not even an inner one. They have eight tentacles. The tentacles have suction cups on them and are used to hold onto prey. The tentacles also have taste sensors that let the octopus know if what it grabbed is worth eating.
Octopuses establish dens in crevices, under rocks, or in man-made objects like flowerpots. They use dens to lay eggs and hide from predators. Their soft, fleshy bodies lack shells, allowing them to squeeze into tiny spaces.

The octopuses of the genus Grimpoteuthis are also known as Dumbo octopuses from the ear-like fins protruding from the top of their head-like bodies, resembling the ears of Walt Disney's flying elephant.
The octopus will squirt purple 'ink' at a supposed predator as a defense mechanism.
The octopus is considered to be one of the most intelligent sea creatures.

Octopus Classification - Received from Jeff Vukovich in Fox River Grove, IL
Q: What Kingdom, Phylum, class, order, family, Genus, and species do octipi belong to?
Octopuses, squids, cuttlefish and the chambered nautilus belong to class Cephalopoda, which means 'head foot'.
Octopuses swim headfirst, with arms trailing behind
While all cephalopods can move by jet propulsion, this is a very energy-consuming way to travel compared to the tail propulsion used by fish.
Octopus
Retina contains 20 million photoreceptors.
The eye has a flicker fusion frequency of 70/sec in bright light.
The pupil of the eye is rectangular.
Has chemoreceptors (taste receptors) on the suckers of their tentacles.
The octopus can use its tentacles to pull apart shells. If this proves to be too difficult, they can use their hard beaks to either crack or drill into the shells.
Diet: Octopus, squid, and fish.
Lifespan: 10-15 years. Up to 20 in captivity.

Juveniles and adults show a wide variety of prey, mostly such as conchs, clams, crabs, horseshoe crabs, shrimps, sea urchins, sponges, fishes, squids, and octopuses.
They eat squid and octopus, which are sucked into the mouth whole. The whale's head is huge. In addition to containing a very large brain, it houses the wax-filled spermaceti organ. Scientists are still trying to learn what this organ does.
Sea otters mainly eat sea urchins, crabs, clams, mussels, octopus, other marine invertebrates, and fish. In order to capture food, sea otters dive to the bottom in 5 to 250 feet of water.
The albatross feeds mostly on squid, octopus, salps and fish, a proportion of which is carrion. This scavenging behaviour in the wake of fishing vessels is leading them to becoming a threatened species.
Eats primarily medium to large squids, sometimes also octopus and various fishes. Large males at high latitudes also take large quantities of demersal and mesopelagic sharks, skates and fishes (Gosho et al. 1984, Jefferson et al.1993, Perry et al.
Halibut feed on almost any animal they can fit in their mouths: animals found in their stomachs include sand lance, octopus, crab, salmon, hermit crabs, lamprey, sculpin, cod, pollack and flounder.
The name polyp was given to these organisms from their supposed resemblance to an octopus (Fr. poulpe), with its circle of writhing arms round the mouth.
Sperm whales feed primarily on squid but also supplement their diet occasionally with octopuses. Beaked whales eat both fish and squid. Toothed whales have conical shaped teeth that are especially suited for grasping onto slipppery prey.
The Mediterranean monk seal eats fish and octopus.
Behavior:
There are contradictory reports as to whether the Mediterranean monk seal has a diurnal or nocturnal feeding cycle (Israels 1992). Births frequently take place in caves or grottoes.
It eats squid, octopus, and fish. The Soupfin lives in temperate waters almost worldwide and migrates long distances to cooler water for giving birth.

They eat a wide variety of invertebrates, including clams, snails, worms, sea stars, sea urchins, crabs, squid, octopuses, and abalone. Alaskan sea otters also eat fish.
The Walrus eats clams, cockles, mussels, shrimp, worms, sea cucumbers and octopuses as well as fish. The Inuit have hunted the Walrus for thousands of years and use every part of it in their traditional dress and their food.
Primarily fish, squid, crustaceans and octopus.
Notes
Calves are not white like the adults; they are blue to brownish-red for in their first year; in the second year they are gray to blue and by the 6th year, they are white.
Adults feed on fish, squid, octopus, crustaceans and jellyfish. In some areas they are drawn towards discards from fishing fleets, which puts them at risk of being killed on long-line fishing hooks.
Their food varies according to the season and location, but fish, octopus and prawns are their common food. The seals are able to remain underwater for up to 45minutes, diving to about 720m in search of prey.
They also feed on invertebrates such as crab, shrimp, clams, worms, octopus, squid, and other bottom dwelling creatures. Since they don't have many big, sharp teeth to grab their prey, they use suction to trap it into their mouths.
Food habits are almost unknown. They are known to eat octopus, squid, and fish. Nothing is known about their reproductive habits; in captivity, they have mated with bottlenose dolphins and produced hybrid offspring.
In the wild, sea otters eat a wide variety of benthic invertebrates like clams, crabs, urchins, snails, octopus, mussels and sea stars. They may eat fish. Individuals seem to have food preferences they learn from their mothers.

bouncing sound off of objects to determine their location—to hunt and use a series of high-pitched clicks to stun prey.
