Conus geographus - How a snail eats a fish

Insulin is widely known as the hormone used to treat diabetic sufferers. It is responsible for countering the effects of another hormone, called glucagon, to restore blood sugar levels within.

The Geographic Cone Snail (Conus geographus) shows its siphon and proboscis. This snail is also humorously called “the cigarette snail” since if one stings you, you allegedly have time for one cigarette before dying.

Unexpected Deadly Beauty

Cone-snails found in the South Pacific and Indian oceans, have poisonous barbs that cause paralysis and occasionally death if you touch them. The Geographer Cone is probably the most dangerous one of all.

Conus geographus Linnaeus, 1758  Geography cone, 129mm  Conus geographus is the largest of the fish-eating cone shells and is also the most dangerous. Its venom has adapted to become powerful enough to quickly stun or kill a prey fish. It wouldn't do the cone much good if the fish were stung and escaped, only to die somewhere else. In addition to having highly virulent venom, it also has an aggressive attitude.

While most cone shells will retract within the shell when disturbed and show little or no inclination to sting humans, Conus geographus will frequently start waving about its stinger looking for a victim when it is picked up. You have to watch this one carefully. They live in a variety of seaward reef and lagoon habitats, and like many other cones, are nocturnally active.

Geography cone, Conus geographus Because all Conus snails are venomous and capable of "stinging" humans, live ones should be handled with great care or preferably not at all. The species most dangerous to humans are the larger ones which prey on small bottom-dwelling fish.
