Cucumbers or Aliens?

I just harvested a dozen Cucumber that are 18 to 24 inches long and over 2 inches in diameter.   Never seen anything like them.   The rains have been near perfect in timing.  The soil great in this area which is a new spot this year for the vegetable garden.  I have used only Espoma organic products.  But I still can't quite explain this.   Here is a picture of half of today's harvest.  And there are still many more Cucumbers on this vine.
