Gastropod shellThe gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection.
MusselMussel (ˈmʌsəl) is the common name used for members of several families of bivalve molluscs, from saltwater and freshwater habitats. These groups have in common a shell whose outline is elongated and asymmetrical compared with other edible clams, which are often more or less rounded or oval. The word "mussel" is frequently used to mean the bivalves of the marine family Mytilidae, most of which live on exposed shores in the intertidal zone, attached by means of their strong byssal threads ("beard") to a firm substrate.
Strombus graciliorStrombus gracilior, common names the Eastern Pacific fighting conch, or the Panama fighting conch, is a species of medium to large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. The length of the shell varies between 40 mm and 95 mm, the width may attain 50 mm. The high spire is covered with subsutural spines or pointed nodes on the shoulder of the whorls. The color of the shell is yellowish to yellowish-brown, interrupted in the middle with a lighter band.
JewelleryJewellery (or jewelry in AmE) consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold often combined with gemstones, has been the normal material for jewellery, but other materials such as glass, shells and other plant materials may be used.
Lobatus raninusLobatus raninus, common name the hawk-wing conch, is a species of medium to large sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. The maximum recorded shell length is 121 mm or up to 130 mm. Like other species in the same genus, Lobatus raninus has a robust, somewhat heavy and solid shell, with a distinct stromboid notch. The body whorl is dorsally ornamented by characteristic coarse spiral ridges. The posterior expansion of the flaring outer lip is always lower than the spire.
Conomurex luhuanusConomurex luhuanus, commonly known as the strawberry conch or tiger conch, is a species of medium-sized sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. C. luhuanus is found in sandy habitat among corals in the Indopacific region. They feed on algae or detritus, move with a modified foot, and have complex eyes compared to other gastropods. The shell of C. luhuanus ranges from a more common length of 5 cm, to a maximum length of 8 cm. C.
Titanostrombus goliathTitanostrombus goliath, previously known as Lobatus goliath and Strombus goliath, common name the goliath conch, is a species of very large edible sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs. T. goliath is one of the largest mollusks of the Western Atlantic Ocean, and also one of the largest species among the Strombidae. It was once considered endemic to Brazil, but specimens have also been recently found in the waters of Barbados.
