Trumret Triton

The tall, pointed spire, which invariably lacks the apical whorls, is less than half the height of the shell. The broad body whorl usually has two prominent varices (as does each spire whorl). The smooth, broad, and flattened spiral ribs on the body whorl have deep grooves and an occasional thin, extra rib between. Suture is well impressed and the rib below each whorl is wavy and puckered. Siphonal canal is broad and short. Thin folds along the columellar wall. Creamy, with dark brown blotches and crescents. Aperture orange-brown, with white channels between teeth on outer lip. columellar teeth white, dark brown between.

Pink Conch

Moderate spire. Short, strong spines at the shoulders of the whorls. Coarse, flat, spiral ridges; spiral cords; axial striae; coarse axial ribs and folds especially on the parietal wall. Flared lip is produced posteriorly to almost level with the apex, and lip edge is wavy and simple. Narrow but deep stromboid notch. Heavily callous, smooth columella. Wide and glazed parietal area. Short, open and recurved siphonal canal. Cream and white; aperture a rich, shining rose pink with yellow shading. This species is taken in huge quantities for food and sometimes produces a pink pearl.

Chambered Nautilus

A lightweight, thin-shelled species, it is spirally coiled, but this is only obvious when the is sectioned. The shell is also partitioned; the resulting chambers are connected to each other by a hollow tube. It is bilaterally symmetrical, with a large aperture but no umbilicus. White or creamy color, with zebralike, reddish stripes radiating from the umbilical region though not extending onto the broadest part of the body whorl.

Chambered Nautilus (Polished)

A lightweight, thin-shelled species, it is spirally coiled, but this is only obvious when the is sectioned. The shell is also partitioned; the resulting chambers are connected to each other by a hollow tube. It is bilaterally symmetrical, with a large aperture but no umbilicus. White or creamy color, with zebralike, reddish stripes radiating from the umbilical region though not extending onto the broadest part of the body whorl.

Red Hellmet

A thick, heavy shell with a low spire, and a large aperture ending with a small, ipturned siphonal canal. It is ornamented with three or four rows of blunt knobs, decreasing in size towards the anterior end, with smaller tubercles and pitted grooves between the rows. Above the siphonal canal  distinct, widely spaced vertical riblets are bisected by a single, equally distinct spiral riblet. There are about 22-24 teeth along the outer lip. Body whorl and spire mottled with shades of red and brown; vertical riblets and spiral riblet whitish. Columellar folds white, dark brown between.

Beech Cone

Shell large to very large, broadly and ventri�cosely conical in shape and ornamented with numerous black dots spirally arranged on the last whorl. Sculpture consists of numerous spiral ribs at base. Shoulder roun�ded and spire usually low. Aperture wide and white, outer lip smooth and moderately thick. Color yellow, a stubby cone with prominent spiral ridge at base.

Asian Murex

A very large, heay shell with a low spire and inflated body whorl, angled at the shoulder. Each whorl has three varices, between which there may be one or two, knobbly vertical ribs. Both varices and siphonal canal have short, frilled spines. Fine spiral ridges cover all whorls. The outer lip has a sawtooth edge and, toward its lower end, a prominent tooth. The columella is smooth. White, with brown ridges and blotches; columella pink.

Wawy Spindle

Shell large, solid, heavy and characterized by numerous strong nodules at the shoulders. Spire high with impressed sutures. Sculpture consists of many spiral ribs at spire whorls, weak or obsolete at body whorl. Axial ribs strong at early whorls, reducing to nodules at shoulders of later whorls. Aperture ovate and white, outer lip denticulate and lirate at inner margin. Parietal wall white and calloused, columella plicate. Siphonal canal long. Color cream white. Distribution: Vung Tau, Quang Ngai, Ninh Thuan, Binh Thuan, etc. Size: 60-235 mm

Oyama'a Frog Shell

A solid but not very heavy shell with an inflated body whorl and a tall spire with a deep, uneven suture. The spiral ribs are strongest around the periphely of whorls where they override prominent, bluntly pointed tubercles. There may be three or four additional spiral ribs below peripheral ones on body whorl. The broad, thin outer lip is wrinkled and bluntly toothed within. The parital shield is thin and wide; the columella has slender folds. White in color, with brown spiral lines.
