What is a Seashell?
Una concha es la parte
universalmente reconocido identifiable de una creatura conocido como un mollusk,
A shell is the most universally
identifiable part of a creature known as a mollusk.
Mollusks are invertebrate animals (think of a snail) with an
unsegmented, basically symmetrical body, generally consisting of head, foot,
visceral hump and mantle. Mollusks are descendants from primitive wormlike creatures
inched around in the ooze of primeval seas millions of years ago. As dissolving
land masses began to feed salts and chemicals into oceans, the first mollusks
digested them and eventually used them to build durable shelters. See the rest

Classifications of Mollusks
All mollusks have soft bodies. In fact, Mollis is Latin and Malakos is Greek
for soft. The study of mollusks is known as Malacology. Most mollusks develop
hard shells to protect them from their hostile environment. Their fleshy mantle
secretes a shell in generally a single or pair of valves. Based on their shell
type, scientists and educators engaged in Malacology have classified mollusks
into six classes. See the rest of the article
How Shells are Named
Shells are named using Systema Natuae which was developed by Swedish naturalist
Karl Linne. This system gives each species a two part Latinized name consisting
of genus and species. A genus name is like a persons surname. It appears first
and is always capitalized. The species name is like a persons first name and
is never capitalized. Following the Latin binomial comes the name of the person
who scientifically proposed the binomial. Latin is used because it is a "dead"
and unchanging language.
