Amalda Anomala
''Amalda'' is a genus of medium-sized sea snails, a marine gastropod mollusc in the family Ancillariidae, the olives and allies.Bouchet, P. (2014). Amalda H. Adams & A. Adams, 1853. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=390993 on 2015-01-18 Description The thin shell is not umbilicated. The spire is elongated with the suture enamelled. The primary spire callus covers most of the spire, including at least part of the protoconch, leaving in most cases only the first protoconch whorl exposed. The inner lip has the callus moderate, defined. The outer lip is simple. Distribution These snails usually live in the sand in fairly shallow water in tropical and temperate regions of the world with a particularly rich fauna in Australia and the Indo-West Pacific. Most species are predators of marine bivalves. In general, both shallow and deep-water species of ''Amalda'' tend to have relatively narrow distribution ranges ...

Amalda australis (G.B. Sowerby I, 1830). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=409967 on 2014-01-30 Description The length of the shell attains 52 mm, its diameter 23 mm. The shell is elongate and fusiform, with a smooth, glossy surface. The Spire (mollusc), spire is relatively short compared to the large body whorl, and the overall shape is sleek and streamlined, allowing the snail to easily burrow into sand. The coloration of the shell varies from creamy white to light brown, often with subtle darker bands or streaks. The Aperture (mollusc), aperture is long and narrow, with a thin outer Lip (gastropod), lip. The inner lip and Columella (gastropod), columella are typically coated with a thin callus.

Amalda Angustata
''Amalda angustata'' is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae. Description The length of the shell varies between 12 mm and 17 mm; its diameter 5.4 mm. The shell is elongated and fusiform, with a slender, tapering shape. It has a high, pointed spire, typically smooth and glossy, with well-defined whorls. The overall appearance of the shell is sleek and streamlined. The body whorl is the largest and forms the majority of the shell's length. It is adorned with fine spiral striations, often subtle, giving the shell a polished look. The aperture is narrow and elongated, occupying a significant portion of the shell's height. The outer lip is thin and smooth, curving gently at the base. The siphonal canal is relatively short and open, while the inner lip is coated with a thin callus, extending slightly onto the body whorl. The shell tends to be pale, often a greyish or creamy white, sometimes with faint bands or markings that enhance its del ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amalda Allaryi
''Amalda allaryi'' is a species of sea snail, a marine gastropod mollusc in the family Ancillariidae, the olives. Description The length of the shell attains 65 mm. The shell is ovate-fusiform with a cyrtoconoid spire (approaching a cone in shape, but with convex sides). The primary spire callus is thick and weakly micro-shagreened, covering all whorls except for 1–1.5 protoconch whorls, making it impossible to count or measure the whorls accurately. The first protoconch whorl has a diameter of 0.84–1.02 mm (mean 0.92 mm, n = 3). The secondary callus is also thick, merging seamlessly with the parietal callus without a visible border, and extends to the anterpenultimate whorl. The plication plate features 2–3 ridges, with the lowest one being the weakest, and the columella is smooth. The olivoid groove is very shallow, almost indistinct, and the labral denticle is very small and obtuse. The upper anterior band is weakly convex, with the rear edge of the anterior plate di ...

Amalda Albocallosa
''Amalda albocallosa'' is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae. Description The length of the shell attains 51 mm, its diameter 18 mm. (Description of † ''Ancilla okawai'') The shell is subfusiform, tending toward a cylindrical shape. The spire is very short, blunt at the apex, and completely covered by callus, which features several fine spiral grooves. This callus also extends over the upper portion of the body whorl and descends to cover the upper part of the inner lip. The body whorl is finely striated with spiral lines, and where it meets the spire, there is a shallow excavation. Near the base, two spiral bands are present, one above the other. The upper band is narrower and bordered by grooves on both sides, while the lower band is one and a half to twice as broad, with a ridge running through its center. Below the lower band, the base is smooth and separated from the lower part of the inner lip by a deep, broad valley. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amalda Alabaster
''Amalda alabaster'' is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae. Description The length of the shell attains 26.7 mm, its diameter 13.5 mm. The shell is small, reaching up to 27 mm in length, with an ovate fusiform shape.

The shell is uniformly white in color and is semitransparant. Distribution This marine species is endemic to and occurs off south-eastern New Caledonia at depths between 180 m and 280 m.
