An Old Fisherman's Warning

Beware the slippery squid, my son.
For, though you are a man,
The devious reach of this unfathomable beast
Will break you if it can.

Since first we sailed upon the sea
To reap it's bounteous treasure,
The ghostly squid has made its bid,
To take our catch with pleasure.

And, "How?" you ask, from such small beasts
Could such a problem be?
The little one is but the young
Of monsters in the sea.
