Collecting beach shells is a common hobby among ocean lovers. Shells come in many shapes, sizes, and colours. Seashells come from animals that live in the ocean, known as mollusks. Mollusks are invertebrates that do not have an internal skeleton. These invertebrates use the shells as protection. A mollusc lives inside its shell, taking it wherever it goes. When the mollusks dies or grows out of its shell, the shell sinks to the ocean floor and lies vacant until another inhabitant claims it, or it washes up on the beach shore.

The most common type of seashell found on a beach is the cockleshell. These shells come in a variety of sizes and are a common home to clams. The shells are round or heart-shaped and have a ribbed texture. They come in many sizes and colours. Depending on the location of the shell, colours may vary from beige and blue, to purple and pink. Their colour is affected by the natural elements surrounding the shell such as excessive sun exposure and extreme ocean activity.

Conch shells are normally the homes to snails and hermit crabs. Their spiral shape makes them very distinguishable. Considered a great find, conch shells can become as large as 12-inches and weigh up to five pounds. In some cultures, conch shells are used for ritual or religious activities. Blowing into them reveals a deep, trumpet-like sound.
