Tiberia minuscula is a species of minute sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies. [1] [2]

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

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 hierarcical 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".

Distribution

This marine species occurs in the following locations: [1]

Canary Islands Archipelago in the Atlantic and autonomous community of Spain

The Canary Islands is a Spanish archipelago and the southernmost autonomous community of Spain located in the Atlantic Ocean, 100 kilometres west of Morocco at the closest point. The Canary Islands, which are also known informally as the Canaries, are among the outermost regions (OMR) of the European Union proper. It is also one of the eight regions with special consideration of historical nationality recognized as such by the Spanish Government. The Canary Islands belong to the African Plate like the Spanish cities of Ceuta and Melilla, the two on the African mainland.

Cape Verde Country comprising ten islands off the Northwest coast of Africa

Cape Verde or Cabo Verde, officially the Republic of Cabo Verde, is an island country spanning an archipelago of 10 volcanic islands in the central Atlantic Ocean. It forms part of the Macaronesia ecoregion, along with the Azores, Canary Islands, Madeira, and the Savage Isles. In ancient times these islands were referred to as "the Islands of the Blessed" or the "Fortunate Isles". Located 570 kilometres (350 mi) west of the Cape Verde Peninsula off the coast of Northwest Africa, the islands cover a combined area of slightly over 4,000 square kilometres (1,500 sq mi).
