arms (8) - eight short limbs, each of which has two rows of suction cups on the lower side; the arms hold the food while the squid bites it into swallowable pieces. beak and mouth - the parrot-like beak on the mouth is used for biting food into small pieces. The beak and mouth are surrounded by the bases of the arms and tentacles. clubs (2) - the ends of the tentacles, which have toothed suckers. eye - an organ used to see; squids have two, very large eyes (they are large in proportion to the size of the body). feeding tentacles (2) - the two, long tentacles are used for obtaining prey; they have toothed suckers only near the tip. fins - two flaps on the mantle that are used to stabilize the squid during swimming. head - the small part of the body between the mantle and the arms; the head contains the eyes, the brain, and the muscular buccal mass (which crushes the food). mantle - the large part of the squid in front of the head; inside the mantle are the stomach, gills, ink sac, pen, reproductive organs, and many digestive organs. siphon - a tube-like organ on the lower side of the head; it expels water forcefully, enabling the squid to propel itself through the sea.
