Sea snail common name for snails that normally live in saltwater

Sea snail is a common name for snails that normally live in salt water, in other words marine gastropods. The taxonomic class Gastropoda also includes snails that live in other habitats, such as land snails and freshwater snails. Many species of sea snails are edible and exploited as food sources by humans.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Conidae family of molluscs

Conidae, with the current common name of "cone snails," is a taxonomic family of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea.

Description

The size of the shell attains 29.4 mm. Conus lyelli shows tubercles on all postnuclear whorls. This species is different from any known extant species. This suggests that it, along with Conus xenicus, may be members of an extinct clade of cone snails.

Whorl (mollusc)

A whorl is a single, complete 360° revolution or turn in the spiral growth of a mollusc shell. A spiral configuration of the shell is found in of numerous gastropods, but it is also found in shelled cephalopods including Nautilus, Spirula and the large extinct subclass of cephalopods known as the ammonites.

Clade A group of organisms that consists of a common ancestor and all its lineal descendants

A clade, also known as monophyletic group, is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life".

Distribution

This marine species is only known in the fossil state from the Neogene of the Dominican Republic.

The Neogene is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.03 million years ago (Mya) to the beginning of the present Quaternary Period 2.58 Mya. The Neogene is sub-divided into two epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hörnes (1815–1868).

Dominican Republic country in the Caribbean

The Dominican Republic is a country located in the island of Hispaniola, in the Greater Antilles archipelago of the Caribbean region. It occupies the eastern five-eighths of the island, which it shares with the nation of Haiti, making Hispaniola one of two Caribbean islands, along with Saint Martin, that are shared by two sovereign states. The Dominican Republic is the second-largest Caribbean nation by area at 48,671 square kilometers (18,792 sq mi), and third by population with approximately 10 million people, of which approximately three million live in the metropolitan area of Santo Domingo, the capital city.
