Cone snails are fascinating marine creatures known for their beautiful, cone-shaped shells. They inhabit warm, tropical waters and can be found in coral reefs and sandy areas. These snails are unique because they are venomous, using a specialized tooth to inject toxins into their prey, which mainly consists of small fish and other marine animals. Despite their small size, cone snails can be dangerous to humans. Their venom can cause serious health issues, and some species are even lethal. Researchers are studying their toxins for potential medical applications, including pain relief and treatments for conditions like cancer and neuropathic pain.
