The squids (Cephalopoda) are a class of animals belonging to the tribe of molluscs (Mollusca). The scientific name, Cephalopoda, is derived from the Greek and literally means cephalopods. This name was chosen because the arms are in a circle around the mouth of the animal.
Cuttlefish are only found in salt water and live in all seas. They are able to change color. Most squids grow fast and have a short life, usually only live one to two years, with the exception of several deep-sea and pool species and the nautiluses that can grow much older.
They move by pumping water into their mantle that they force out again, along the siphon. All squids are carnivores. The food mainly consists of fish, crabs, lobsters and molluscs that they catch with their suction cups on their gripping arms. They would also occasionally practice cannibalism.
Cuttlefish are characterized by the position of their arms around their mouth. They have eight arms with suction cups, sea cats and squids have two more feeding tentacles above it. The only exception is Nautilus pompilius which has about 90 tentacles without suction cups.
Cuttlefish have well-developed eyes with a toroidal brain around the intestinal tract. They have a hardened parrot-like beak, on top of that most species also have a rasp tongue (the so-called radula) to tear the prey into pieces. The entrails and delicate organs are located in the mantle (the fried rings are vertical slices of this mantle). Oxygen removes the squid from the water with the help of gills (2 to 4), water is drawn in by the rhythmic movement of the mantle and then removed again along the siphon. This siphon is also used for spraying ink and for excretion.
