There are many types of shells found on beaches worldwide, each with unique characteristics. All shells come from marine mollusks and can vary in size and shape. Common types include clams, sand dollars, and snail shells, which can also be used as musical instruments.
There are hundreds of different types of shells, and at any given time, there are countless amounts of shells lying on the ocean floor. Some are homes to living creatures, and others are empty shells waiting to be washed ashore. Some shells are native to particular areas of the world; however, there are several types that can be found on any beach. To understand the variety of shells, it is important to pay attention to the specific characteristics of each shell, including size and shape.
Every shell has one thing in common: it comes from a species of marine mollusk. There are four different classes of marine molluscs and there are different types in each class. All marine molluscs have a shell, unique to their owners.
Some shells are small and some are large, depending on the species and age of the creature. The shells are commonly found washed up on sandy beaches and shorelines after the mollusk dies. The ocean and the sun make subtle changes to the shell during its journey to land, including surface and color changes. As a result, shells are often whiter and smoother on land than they are in the ocean.
One of the most common types of shells is the clam and is found on beaches around the world. A clam is a small saltwater clam. It is edible and is enjoyed worldwide as a fresh fish dish. Among the more than 200 varieties of thistles, there are two basic types of shells – smooth and ridged – and they look similar to each other.
The sand dollar is another common type of shell and comes from a sea creature of the same name. The shell can also be called test. Sand dollars look very different from other types of seashells. They are flat and round and have a bleached appearance.
The shell, which once housed some species of snails, can vary greatly in size. This type of shell is valued for its beauty and for the sound that air makes when it is blown through it. Shells can actually be used as musical instruments.
Some of the other types of shells include scallops, starfish, oysters, abalone shells.
