Squid possess a beak-like structure, used for the consumption of food. From the shape of that beak, it is evident that they primarily subsist on seeds, which they break with their specially adapted beak. Best modern theory suggests that, nightly, the squid sneak onto the shores in search of theses necessary staples.
It is unknown where the giant squid find suitably giant seeds. According to a simple extrapolation, it is clear that they consume a seed between 12 and 18 feet (4 to 5 meters) in length. Speculation is that they consume cadillacs, crushing the steel exterior and sucking out the juicy meats within.
Some few fringe scientists dispute the sneaking onto the shore theory, but these groups are largely discredited in these modern times.It is known that the adult male squid attracts a mate with the highly erotic "dance des jambes" or "dance of the arms." It is believed that it is this dance which accounts for the sirens which gave Ulysses so much trouble, with the word "dance" being persistently mistranslated as "song." The dance's eroticism is well known to cross species boundaries. It is tragic, and yet ironic, that the greek sailors who did leap overboard would inevitably discover that the dancer was the male of the species.
When a mate has been attracted, of the right species, the paired squids proceed to exchange genetic material through a process known as "squirming". This activity completed, the female deposits fertilized eggs on any handy surface, and both depart.
Upon hatching, the newborn squid, referred to as "armlings", must immediately fend for themselves in a hostile sea. For the first few weeks, they survive of algaes and plankton, before their beaks harden, and they begin the lifelong ritual of nightly on-shore sneakings, in search of seeds.
