Antiguraleus aeneus is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. [1]

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".

Mangeliidae is a monophyletic family of small to medium-sized, predatory sea snails, marine gastropod mollusks in the superfamily Conoidea.

Description

The length of the shell attains 11 mm, its diameter 4 mm.

(Original description) The small, solid shell has a cylindro-fusiform shape. It is polished and constricted at the sutures. On decollate specimens six whorls remain, divided by linear sutures. The colour of the shell is amber-brown, with ochraceous reflections. The sculpture shows prominent, arcuate ribs, each slightly overhanging the one below, seven to a whorl, consecutive on the spire, smaller on the body whorl where they do not reach the base. On the base and snout are six revolving threads. The aperture is rather wide, flanked by a tall and thick varix. The edge of the outer lip is thin, insinuate at the base. The columella is perpendicular and concave. The siphonal canal is short and wide. The sinus is wide and shallow. A prominent callus knob is prominent at the lip insertion. [2]

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.

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.

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.

Distribution

This marine species is endemic to Australia and occurs off Queensland.

Queensland North-east state of Australia

Queensland is the second-largest and third-most populous state in the Commonwealth of Australia. Situated in the north-east of the country, it is bordered by the Northern Territory, South Australia and New South Wales to the west, south-west and south respectively. To the east, Queensland is bordered by the Coral Sea and Pacific Ocean. To its north is the Torres Strait, with Papua New Guinea located less than 200 km across it from the mainland. The state is the world's sixth-largest sub-national entity, with an area of 1,852,642 square kilometres (715,309 sq mi).
