Cowrie
Cowrie or cowry () is the common name for a group of small to large sea snails in the family Cypraeidae. Cowrie shells have held cultural, economic, and ornamental significance in various cultures. The cowrie was the shell most widely used worldwide as shell money. It is most abundant in the Indian Ocean, and was collected in the Maldive Islands, in Sri Lanka, along the Indian Malabar coast, in Borneo and on other East Indian islands, in Maluku in the Pacific, and in various parts of the African coast from Ras Hafun, in Somalia, to Mozambique. Cowrie shell money was important in the trade networks of Africa, South Asia, and East Asia. In the United States and Mexico, cowrie species inhabit the waters off Central California to Baja California (the chestnut cowrie is the only cowrie species native to the eastern Pacific Ocean off the coast of the United States; further south, off the coast of Mexico, Central America and Peru, Little Deer Cowrie habitat can be found; and fur ...

Cypraeidae
Cypraeidae, common name, commonly named the cowries ( cowry or cowrie), is a Taxonomy (biology), taxonomic family (biology), family of small to large sea snails. These are marine (ocean), marine gastropod mollusks in the superfamily Cypraeoidea, the cowries and cowry allies. Shell description Cypraeidae have adult shells which are very rounded, almost like an egg; they do not look like a typical gastropod shell. Their glossy, polished, ovate-shaped shells have beautiful patterns in a variety of colors. These patterns, combined with minor variations in shell form, have led some conchologists to recognize 60 genera and hundreds of species and subspecies. In virtually all of the species in the family Cypraeidae, the shells are extremely smooth and shiny. This is because in the living animal, the shell is nearly always fully covered with the mantle (mollusc), mantle. The upper surface is typically convex, while the ventral side is flattened. Typically, no spire (mollusc), spire is ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Shell Money
Shell money is a medium of exchange similar to coin money and other forms of commodity money, and was once commonly used in many parts of the world. Shell money usually consisted of whole or partial sea shells, often worked into beads or otherwise shaped. The use of shells in trade began as direct commodity exchange, the shells having use-value as body ornamentation. The distinction between beads as commodities and beads as money has been the subject of debate among economic anthropologists. Shell money has appeared in the Americas, Asia, Africa and Australia. The shell most widely used worldwide as currency was the shell of '' Cypraea moneta'', the money cowry. This species is most abundant in the Indian Ocean, and was collected in the Maldive Islands, in Sri Lanka, along the Malabar coast, in Borneo and on other East Indian islands, and in various parts of the African coast from Ras Hafun to Mozambique. Cowry shell money was an important part of the trade networks of Afric ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ovulidae
Ovulidae, common names the ovulids, cowry allies or false cowries, is a family (biology), family of small to large predatory or parasitic sea snails, marine (ocean), marine gastropod molluscs in the superfamily Cypraeoidea, the cowries and the cowry allies.

Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=1747 on 2020-05-25 Distribution The ovulids are a widespread family, occurring mostly in tropical and subtropical waters, with most species in the Indo-West Pacific region. But a few species live in temperate waters. Habitat Ovulids are carnivorous molluscs that feed on polyp (zoology), polyps and tissues of Anthozoa (as do the genera ''Cyphoma'' and ''Pseudocyphoma''). They live on, and eat, soft corals and sea fans, and they are usually regarded as ectoparasites of these Sessility (zoology), sessile colonial organisms, to which they are anchored by a ...

Chestnut Cowrie
''Neobernaya spadicea'', common name the chestnut cowrie, is a species of sea snail in the cowrie family, Cypraeidae. Chestnut cowries can be found in the eastern Pacific Ocean, from central California to Baja California. The chestnut cowrie has a highly glossy shell due to an enamel that is secreted from its mantle. Distribution and habitat The chestnut cowrie is the only species of cowrie in the eastern Pacific Ocean. It can be found in intertidal zones from Monterey, California to Isla Cedros, Baja California. It is common in Southern California, specifically around the Channel Islands. Chestnut cowries are rare in the portion of their range that is north of Santa Barbara, California. Chestnut cowries live in kelp beds and rocky surfaces in intertidal The intertidal zone or foreshore is the area above water level at low tide and underwater at high tide; in other words, it is the part of the littoral zone within the tidal range. This area can include several types of ha ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Maldive Islands
The Maldives, officially the Republic of Maldives, and historically known as the Maldive Islands, is an archipelagic country in South Asia located in the Indian Ocean. The Maldives is southwest of Sri Lanka and India, about from the Asian continent's mainland. The Maldives' chain of 26 atolls stretches across the equator from Ihavandhippolhu Atoll in the north to Addu Atoll in the south. The Maldives is the smallest country in Asia. Its land area is only , but this is spread over roughly of the sea, making it one of the world's most spatially dispersed sovereign states. With a population of 515,132 in the 2022 census, it is the second least populous country in Asia and the ninth-smallest country by area, but also one of the most densely populated countries. The Maldives has an average ground-level elevation of above sea level, and a highest natural point of only , making it the world's lowest-lying country.

Central America
Central America is a subregion of North America. Its political boundaries are defined as bordering Mexico to the north, Colombia to the southeast, the Caribbean to the east, and the Pacific Ocean to the southwest. Central America is usually defined as consisting of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from southern Mexico to southeastern Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes, which has resulted in death, injury, and property damage. Most of Central America falls under the Isthmo-Colombian cultural area. Before the Spanish expedition of Christopher Columbus' voyages to the Americas, hundreds of indigenous peoples made their homes in the area. From the year 1502 onwards, Spain ...
