Cone snail - Conus spp. Venomous, predatory snail, known as the cone snail. This unique snail hunts fish by extending its proboscis, shaped like a harpoon, to temp its prey. When fish come close enough, the snail strikes them with venom 1000 times stronger than morphine, causing paralyses. Cone snail venom is now used in a drug called Ziconotide to relieve chronic pain. In a single sting from one of these molluscs there is enough venom to kill 15 healthy adults.
Healing the Brain with Snail Venom | Why do neuroscientists care about cone snails? Cone snail venom contains neurotoxins that can target specific locations in the brain and spinal cord. For example, some species of cone snail possess a compound that can act on the same receptors as nicotine. These receptors, located on the surface of neurons, help to govern signaling in the brain.
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.
Conus marmoreus, common name the "marbled cone", is a species of predatory sea snail, a marine gastropod mollusk in the family Conidae, the cone snails, cone shells or cones.
