Types Of Seashells And Seashell Collection

Updated on September 10, 2012

Seashells are available in hundreds of types. Even sometimes there can be countless amount of sea shells lying on the floor of the ocean. Some seashells are home to some living creatures whereas others are vacant, waiting to be washed on to drying land.

Most of the types of sea shells can be found on almost every beach but the remaining ones are native to a certain part of the world. Every type of seashell has its own characteristic and to know about the types of sea shells we first have to study those characteristics.

All of the types of sea shells are common in one aspect that they come from any specie which is of marine mollusk. The marine mollusk can be classified into four main classes and there are a number of types of mollusks in every class. All marine mollusks have shells but they are different in type which makes them unique.

Seashell Types

Some sea shells are small while others are big. These sea shells come up to the surface of sandy beaches and shores when the mollusks inside them die.

However some changes occur on them in their journey towards land. These changes are mainly of the color and surface. Basically this is the main thing which discriminates these shells into various types as some of them have very smooth surface and are whiter than they were in the ocean.

Some of the types of sea shells are:
