1.  These marine animals are members of the cephalopod class, which also include octopi, cuttlefish, and nautiluses.   They have two tentacles and eight arms.   (Very bad joke: What branch of the service do squids tend to join?  The ARM-y.)

2.  They cannot live in fresh water, although one species (Atlantic brief squid) seems to tolerate brackish water.  (Apparently, the Atlantic brief squid would enjoy my cooking.)

3.  Most squids top out at about 24 inches in length, but the giant squid has been known to reach a size of 43 feet and the colossal squid may be as long as 46 feet.  (Hey guys, don’t you know size doesn’t matter?)

4.  Sailors in olden days reported seeing squids that would appear to be larger than even the colossal squid, but these claims can’t really be verified.

5.  The Kraken is a squid –like creature of myth and legend (although in its earliest forms it seems to be more crab-like), which is said to have been so large that it could swallow whales and ships.  (After which, it needed a very, very large Alka-Seltzer.)

6.  A giant squid figures prominently and memorably in Jules Verne’s 20,000 Leagues Under the Sea. (You knew that already, didn’t you?)

7.  Need zinc, manganese and copper in your diet?  Squids are high in all of these.  (Order up some calamari tonight!)

8.  In some male squids, the left tentacle is equipped for sexual intercourse.  (Insert your own comment here.)

9.  A squid’s mouth is in the shape of a very hard, crooked beak.

10.  The eyes of the giant squid can measure one foot in diameter, making them the largest eyes of any living creature on Earth (except perhaps the colossal squid; much less is known about the colossal.)  (Imagine the cost of eye shadow when one has a hot date.)
