Cone snails are one of my favourite groups of animals. They're molluscs that can be found in all tropical and sub-tropical waters, usually on coral reefs. They get their name from their beautifully-pattern cone-shaped shells. However, handling live specimens is not recommended as they're highly venomous, with the sting of some species capable of killing a human within a few hours if left untreated. I have a collection of seven Cone snail shells.
