A conch shell is a hard, spiral-shaped shell that comes from marine mollusks, particularly from the family Strombidae. These shells are often large and can be found in various colors, including pink, orange, and white. Conch shells are commonly found in warm, shallow waters of the Caribbean Sea and other tropical regions. Conch shells have been used by humans for thousands of years. They serve various purposes, including being crafted into jewelry, tools, and musical instruments. In some cultures, conch shells are also used as ceremonial items or as a means of communication, producing a loud sound when blown into, similar to a trumpet.
