Trochus camelophorus is a species of small sea snail, a marine gastropod mollusc in the family Trochidae, the top snails. [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 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".

Description

The height of the shell attains 11 mm, its diameter 12 mm. The solid, false-umbilicate, pink shell has a conical shape. Its sculpture shows rounded cinguli of unequal thickness, with rope-like markings, 5 to 6 on the penultimate whorl. Regular radiate riblets cross the cinguli. slightly beading or granulating them. The base of the shell contains 5 to 6 flat spiral ribs, separated by slightly narrower furrows The whole is ornamented with close and fine radiate striae. The colour of the shell is rose, with darker markings above the periphery of the body whorl. The base is yellowish-white, with radiate stripes and spots of light brown. The conical spire has a rounded apex. The protoconch contains two whorls with traces of a spiral sculpture. The five whorls of the teleoconch are slightly shouldered above, flat, the last one sharply angled at the periphery. The suture is marked by a deep groove behind the first roping of succeeding whorl. The aperture is subquadrangular, inside slightly pearly.. The outer and basal lip are slightly convex, forming an acute angle at their junction. The columella is slightly oblique, with a distinct fold above, rounded, and smooth. The false umbilicus is not very deep, and has a strong spiral fold, which is sometimes distinctly grooved, thus having the appearance of two spiral ribs lying close together. [3]

Sculpture (mollusc)

Sculpture is a feature of many of the shells of mollusks. It is three-dimensional ornamentation on the outer surface of the shell, as distinct from either the basic shape of the shell itself or the pattern of colouration, if any. Sculpture is a feature found in the shells of gastropods, bivalves, and scaphopods. The word "sculpture" is also applied to surface features of the aptychus of ammonites, and to the outer surface of some calcareous opercula of marine gastropods such as some species in the family Trochidae.

Body whorl

The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk.

Spire (mollusc)

A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods.

Distribution

This marine species is endemic to New Zealand, known from the northern end of North Island.

North Island The northern of the two main islands of New Zealand

The North Island, also officially named Te Ika-a-Māui, is one of the two main islands of New Zealand, separated from the larger but much less populous South Island by Cook Strait. The island's area is 113,729 square kilometres (43,911 sq mi), making it the world's 14th-largest island. It has a population of 3,749,200.
