Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Snail
Sea snails are slow-moving marine (ocean), marine gastropod Mollusca, molluscs, usually with visible external shells, such as whelk or abalone. They share the Taxonomic classification, taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible Gastropod shell, shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain Neritidae, neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example, species in the genus ''Truncatella (gastropod), Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large and diverse group of animals. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide w ...

Gastropod
Gastropods (), commonly known as slugs and snails, belong to a large Taxonomy (biology), taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and sea slug, slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca. It contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Furongian, Late Cambrian. , 721 family (taxonomy), families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently neontology, extant living fossil, with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater and even terrestrial species. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known extant i ...

Family (biology)
Family (, : ) is one of the eight major hierarchical 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 the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Costellariidae
Costellariidae sometimes called the "ribbed miters" is a Taxonomy (biology), taxonomic family (biology), family of minute to medium-sized predatory sea snails, marine (ocean), marine gastropod mollusks. This family of snails is also sometimes referred to as ''Vexillum'' miters. The main family of miter shells however is Mitridae, a closely related group. The monophyly of this family has been confirmed. Taxonomy This family was previously sometimes known as Vexillidae. ''Latiromitra'' (from family Ptychatractidae) has been found to be closely related to Costellariidae in the molecular phylogeny analysis by Fedosov & Kantor (2010). Description The shell ranges from small to medium-sized, with an elongate shape that is typically fusiform, elongate-fusiform, or turriform. The protoconch is glossy and smooth, usually multispiral and narrowly conical, though it can sometimes be paucispiral and bulbous. The shell often features a high Spire (mollusc), spire, a very narrow Aperture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mozambique
Mozambique, officially the Republic of Mozambique, is a country located in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the south and southwest. The sovereign state is separated from the Comoros, Mayotte, and Madagascar by the Mozambique Channel to the east. The capital and largest city is Maputo. Between the 7th and 11th centuries, a series of Swahili port towns developed on that area, which contributed to the development of a distinct Swahili culture and dialect. In the late medieval period, these towns were frequented by traders from Somalia, Ethiopia, Egypt, Arabia, Persia, and India. The voyage of Vasco da Gama in 1498 marked the arrival of the Portuguese Empire, Portuguese, who began a gradual process of colonisation and settlement in 1505. After over four centuries of Portuguese Mozambique, Portuguese rule, Mozambique Mozambican War of Indepen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Islands
The Marshall Islands, officially the Republic of the Marshall Islands, is an island country west of the International Date Line and north of the equator in the Micronesia region of the Northwestern Pacific Ocean. The territory consists of 29 coral atolls and five main islands as well as 1,220 other very small ones, divided across two Archipelago, island chains: Ratak in the east and Ralik in the west. 97.87% of its territory is water, the largest proportion of water to land of any sovereign state. The country shares Maritime boundary, maritime boundaries with Wake Island to the north, Kiribati to the southeast, Nauru to the south, and the Federated States of Micronesia to the west. The capital city, capital and largest city is Majuro, home to approximately half of the country's population. The Marshall Islands are one of only four atoll based nations in the entire world. Austronesian settlers reached the Marshall Islands as early as the 2nd millennium BC and introduced Southeas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vexillum
The ''vexillum'' (; : ''vexilla'') was a flag-like object used as a War flag, military standard by units in the Roman army. A common ''vexillum'' displayed imagery of the Aquila (Roman), Roman ''aquila'' on a reddish backdrop. Use in Roman army The word ''vexillum'' is a derivative of the Latin word, ''velum'', meaning a sail, which confirms the historical evidence (from coins and sculpture) that ''vexilla'' were literally "little sails": flag-like standards. In the ''vexillum'', the cloth was draped from a horizontal crossbar suspended from a staff. That is unlike most modern flags in which the "hoist" of the cloth is attached directly to a vertical staff. The bearer of a ''vexillum'' was known as a ''vexillarius'' or ''vexillifer''.Vexillum ''Flagspot.net'', retrieved March 18, 2011 Just as in the case of the regimental colors or fl ...
