Florida State Shell

Horse ConchFlorida State Shell - Horse Conch

(Pleuroploca gigantea)

Adopted in 1969

The horse conch (Pleuroploca gigantea), the horse conch, also known as the giant band shell. This shell is native to the marine waters around Florida and can grow to a length of 24". Young shells have orange color; adult shells have orange apertures. The shell is the external skeleton of a soft-bodied animal that inhabits it. The word "conch" comes from the Greek word meaning "shell." The horse conch has been Florida's official state shell since 1969.


At least 535 million years ago, mollusks acquired the ability to secrete a carbonate of lime solution that formed a hard, protective shell around them. The word "conch" comes from a Greek word meaning "shell."
