Coelotrochus carinatus is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails. [1]
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 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".
The height of the shell attains 3.8 mm, its diameter 4.3 mm.

This marine species is endemic to New Zealand and occurs off Three Kings Islands.
The Three Kings Islands, called Manawatāwhi by Māori, are a group of 13 uninhabited islands about 55 kilometres (34 mi) northwest of Cape Reinga, New Zealand, where the South Pacific Ocean and Tasman Sea converge. They measure about 4.86 km² in area. The islands are situated on a submarine plateau, the Three Kings Bank, and are separated from the New Zealand mainland by an 8 km wide, 200 to 300 m deep submarine trough. Therefore, despite relative proximity to the mainland, the islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead Area Outside Territorial Authority, like all the other outlying islands except the Solander Islands.
