Even today divers and beach combers are sometimes overwhelmed by the beauty of cone snails and reach out to grab the lovely creatures.

Rule 30 is a one-dimensional binary cellular automaton rule that displays aperiodic, chaotic behaviour. This automaton is of particular interest because it produces complex, seemingly random patterns from simple, well-defined rules. Wolfram (A New Kind of Science) believes that cellular automata are the key to understanding how simple rules produce complex structures and behaviour in nature. A pattern resembling Rule 30 appears on the shell of the widespread cone snail species Conus…
Cone snails are beautiful but can be deadly. All are venomous and capable of stinging humans even thru gloves and wetsuits. Live ones should be handled with great care or preferably not at all. They use a hypodermic needle-like modified radula tooth and venom gland to attack and paralyze their prey before engulfing it. The tooth is sometimes likened to a dart or harpoon. It is barbed, and can be extended some distance out.
