squid to label

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.
