Aliger Gigas
''Aliger gigas,'' originally known as ''Strombus gigas'' or more recently as ''Lobatus gigas'', commonly known as the queen conch, is a species of large sea snail, a marine gastropod mollusc in the family of true conches, the Strombidae. This species is one of the largest molluscs native to the Caribbean Sea, and tropical northwestern Atlantic, from Bermuda to Brazil, reaching up to in shell length. ''A. gigas'' is closely related to the goliath conch, ''Lobatus goliath'', a species endemic to Brazil, as well as the rooster conch, ''Aliger gallus''. The queen conch is herbivorous. It feeds by browsing for plant and algal material growing in the seagrass beds, and scavenging for decaying plant matter. These large sea snails typically reside in seagrass beds, which are sandy plains covered in swaying sea grass and associated with coral reefs, although the exact habitat of this species varies according to developmental age. The adult animal has a very large, solid and heavy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strombidae
Strombidae, commonly known as the true conchs, is a taxonomic family of medium-sized to very large sea snails in the superfamily Stromboidea, and the Epifamily Neostromboidae. The term true conchs, being a common name, does not have an exact meaning. It may refer generally to any of the Strombidae but sometimes is used more specifically to include only ''Strombus'' and ''Lambis''. The family currently includes 26 extant, and 10 extinct genera. Distribution Strombid gastropods live mainly in tropical and subtropical waters. These animals are widespread in the Indo-West Pacific, where most species and genera occur. Nearly 40 of the living species that used to belong to the genus '' Strombus'' can be found in the Indo-Pacific region.Abbott, R.T. (1960). "The genus Strombus in the Indo-Pacific". ''Indo-Pacific Mollusca'' 1(2): 33-144 They also occur in the eastern Pacific and Western Atlantic, and a single species can be found on the African Atlantic coast. Six species of strom ...

They are an edible species and important food source for the inhabitants of where they are found. Conchs are most notable for their medium to large-sized ornamental shells. Milk conchs are dispersed among the tropical waters of the Atlantic Ocean, along the coasts and islands of North, Central, and South America.

Gastropod Genera
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda 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 Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Charles Willison Johnson
Charles Willison Johnson (October 26, 1863 – July 19, 1932) was an American naturalist who specialized in entomology (especially Diptera) and malacology, making significant contributions in both fields. He was a mentor and inspiration to many students and young scientists such as William J. Clench (who founded a publication named '' Johnsonia'' in his honor). Johnson was Curator of the Wagner Free Institute of Science, 1888–1903, then was Principal Curator at the Boston Society of Natural History, 1903–1932. He assisted Henry Augustus Pilsbry with '' The Nautilus'', an important American malacological publication. Although both were credited on the title page as "Editors and Publishers", Johnson was the business manager and Pilsbry was the editor, with Johnson acting as editor when Pilsbry was on extended field expeditions. Biography Charles Johnson was born to Albert Fletcher Johnson and Sarah Willison Johnson in Morris Plains, New Jersey. He attended public and private ...

Henry Augustus Pilsbry
Henry Augustus Pilsbry (7 December 1862 – 26 October 1957) was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial mollusks, and others. Biography Pilsbry (frequently misspelled ''Pilsbury'') spent his childhood and youth in Iowa. He was called "Harry" Pilsbry then, and developed an early fascination with the limited variety of mollusks he was able to find. He attended the University of Iowa, and received the Bachelor of Science degree there in 1882, but did not immediately find employment in his field of interest. Instead, Henry Pilsbry worked for publishing firms and newspapers for the next several years, but devoted most of his spare time to the study of mollusks. ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the Endling, last individual of the species, although the Functional extinction, capacity to breed and recover may have been lost before this point. Because a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. More than 99% of all species that ever Life, lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct a ...
