Bellaspira melea is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. [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".

Description

The size of an adult shell varies between 12 mm and 20 mm.

(Original description) The stout shell has a rose pink color, with a whitish band in front of the suture. The blunt smooth protoconch contains about one whorl. The teleoconch contains the five subsequent whorls. The suture is appressed and obscure. The spiral sculpture is apparently absent. The axial sculpture shows (on the body whorl six) strong, stout, wavelike ribs, continuous up the spire, with wide interspaces, and practically vertical0 The surface appears to be smooth but as the specimen is slightly beach worn some minute sculpture may have disappeared. The suture is undulated by the ribs, there is no anal fasciole perceptible. The anal sulcus is narrow, short, with a subsutural callus in front of it. The outer lip is thin, sharp, with a marked varicose swelling behind it. There are no internal lirae. The inner lip is callous. The smooth columella is very short, stout, and straight. The siphonal canal is hardly differentiated from the aperture but deeply cut. [3]

Protoconch

A protoconch is an embryonic or larval shell which occurs in some classes of molluscs, e.g., the initial chamber of an ammonite or the larval shell of a gastropod. In older texts it is also called "nucleus". The protoconch may sometimes consist of several whorls, but when this is the case, the whorls show no growth lines.

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.

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.

Distribution

This species occurs in the Pacific Ocean off Panama.

Panama Republic in Central America

Panama, officially the Republic of Panama, is a country in Central America, bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. The capital and largest city is Panama City, whose metropolitan area is home to nearly half the country's 4 million people.
