When they are deprived of calcium in the water that they live in (which they need to build their shell), smart snails still form long-term memory following two training sessions.

Humans can ingest these naturally occurring toxins by eating shellfish like clams, oysters and mussels,…

What kind of chemicals are found in cone snail venom?

Conantokins are a family of conopeptides found in cone snail venom. The best known member of the family is conantokin-G from the geography cone snail. The chemicals are sometimes called “sleeper peptides” because when they are injected into the brain of young mice they trigger sleep.

How are the shells of sea snails used by humans?

The shells of sea snails are often found by humans as seashells commonly wash up on beaches. Because the shells of many sea snails are attractive and durable, they have been used by humans to make necklaces and other jewelry from prehistoric times to the current day.
