Penniform Cone Shells


I found some penniform cone (Conus pennaceus) shell fragments scattered along the beach on the north shore of Oahu. The cone snails have poisonous darts and some species have even killed humans, but that is rare. This species is even more interesting because it has a pattern on its shell that is very similar to rule 30 cellular automaton. The pattern reminds me of a snow capped mountain range.
