The geography cone is a predatory sea snail that lives on shallow tropical reefs in the Indo-Pacific. It hunts small fish. Its venom is strong enough to kill a person, which makes it one of the most dangerous cone snails.1

It eats small fish. It fires a harpoon-like, venom-tipped tooth into its prey. The harpoon is attached to the snail by a proboscis (a tube-like feeding organ), and the prey is pulled inside to be eaten.1

Its venom is a complex mix of hundreds of different toxins, delivered through the harpoon-like tooth. It has the most toxic sting known among cone snails. Even the most venomous cone snails take about one to five hours to kill a healthy adult, but medical care must still be prompt.1

There are reports of about 36 human deaths over the past 300 years. Live specimens should be handled with extreme caution.1

Gịnị ka ọ na-eme mgbe ụjọ tụrụ ya?

Most of the venom's toxic compounds are believed to be used for defence rather than feeding.1

Ọ bụrụ na ọ gbaa

  • There is no antivenom for a cone snail sting. Treatment consists of keeping the victim alive until the symptoms wear off, so prompt medical care is essential.1

Eziokwu

1

Its venom contains a form of insulin, which it uses to stun fish. Once the venom passes through a fish's gills, the fish goes into hypoglycaemic shock (a dangerous drop in blood sugar).1

2

Apart from the tulip cone snail, no other known living thing is known to use its own biological insulin as a weapon.1

3

Research shows that some proteins from cone snail venom can be up to 10,000 times more effective than morphine as painkillers, without morphine's addictive properties and side effects.1

4

Of the venom's 100 to 200 toxic peptides, only 15 to 20 are used for feeding.1

5

Adult geography cones can fall prey to sea turtles, rays, birds and human shell collectors.1

Onye na-ekpughe akụkọ ụgha

Akụkọ ụgha: The nickname 'cigarette snail' means a sting gives you just enough time to smoke a cigarette before you die.

Eziokwu: This is a gallows humour exaggeration. Even the most venomous cone snails take about one to five hours to kill a healthy human.1
