Haminoea Alfredensis
''Haminoea alfredensis'', common name the South African bubble snail, is a species of sea snail or bubble snail, a marine opisthobranch gastropod mollusc in the family Haminoeidae, one of the families of bubble snails. Taxonomy The species was first described by Paul Bartsch in 1915 Oskars and Malaquias 2020 found that the original description of Haminoea natalensis shows a shell with longitudinal growth lines and a large anterior aperture, which is a close match to H. alfredensis. Due to this Oskars and Malaquias considered H. natalensis as a potential senior synonym of H. alfredensis. However, the authors refrained form synonymising the names due to the type shells of H. natalensis being lost, and due to the name of the name being mostly connected to Pacific haminoeids of the genus Haloa Pilsbry, 1921 mainly the species now known as Haloa wallisii. The name of this species will be in question until it is properly revised. The editors of World Register of Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible 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 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'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. 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 when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
Opisthobranch
Opisthobranchs () is now an informal name for a large and diverse group of specialized complex gastropods which used to be united in the subclass Opisthobranchia. That taxon is no longer considered to represent a monophyletic grouping. Euopisthobranchia is a taxon containing a revised collection of opisthobranchs, and that taxon is considered monophyletic. Euopisthobranchia does not include some "traditional" opisthobranchs such as the Sacoglossa and the Acochlidiacea. The subclass Heterobranchia now contains all the species which used to be assigned to Opisthobranchia, plus all the species in the Pulmonata. The subclass Opisthobranchia included species in the order Cephalaspidea (bubble shells and headshield slugs), the sacoglossans, anaspidean sea hares, pelagic sea angels, sea butterflies, and many families of the Nudibranchia. ''Opisthobranch'' means "gills behind" (and to the right) of the heart. In contrast, ''Prosobranch'' means ''gills in front'' (of the heart). Opist ...

Gastropod
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.

Mollusc
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. 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. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. 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 invertebrate species.

Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Haminoeidae
Haminoeidae, commonly known as the haminoeid bubble snail family, is a taxonomic family of sea snails, marine opisthobranch gastropod mollusks in the superfamily Haminoeoidea. The name of this family has long been controversial, and used to be Atyidae or Atydidae. Another, but incorrect, spelling was Haminaeidae (See (ICZN) 2000. Opinion 1942). A number of genera have been proposed for this family, but the species are hard to identify (or sometimes impossible to identify) by looking only at the external characteristics. Until the internal anatomy of 'wet' specimens has been fully described, the status of many of the genera listed here is uncertain. Distribution These bubble snails occur in all warm or temperate seas. Habitat These are sand dwellers or they live on muddy bottoms, in bays, estuaries, and close to the shore in tidepools. Description of the live animal These are colorful snails, that can partially take the color of the sea floor. Their large cephalic shield is ro ...

Paul Bartsch
Paul Bartsch (14 August 1871 Tuntschendorf, Silesia – 24 April 1960 McLean, Virginia) was an American malacologist and carcinologist. He was named the last of those belonging to the "Descriptive Age of Malacology". Early life Bartsch emigrated with his parents to the U.S.A in 1880, first to Missouri and then to Burlington, Iowa. As a child, he took up jobs in his spare time in several employments. He soon took an interest in nature, first by keeping a small menagerie at home, and during his high school years, collecting birds and preparing skins. He established a natural-history club in his home with a little museum and a workshop. By the time he went to the University of Iowa in 1893, he had collected 2,000 skins. Among his professors at the university were the University of Iowa were the geologist Samuel Calvin, botanists Thomas H. Macbride and Bohumil Shimek, and the zoologist Charles C. Nutting. He graduated from the university with a B.S. in 1896, and M.S. in 1899, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haloa Pilsbry, 1921
Haloa or Alo (Ἁλῶα) was an Attic festival, celebrated principally at Eleusis, in honour of Demeter (Δήμητρα, η Αλωαίη), protector of the fruits of the earth, of Dionysus, god of the grape and of wine, and Poseidon (Ποσειδώνας ο Φυτάλμιος), god of the seashore vegetation. In Greek, the word hálōs (ἅλως) from which Haloa derives means “threshing-floor” or “garden.” While the general consensus is that it was a festival related to threshing—the process of loosening the edible part of cereal grain after harvest—some scholars disagree and argue that it was instead a gardening festival. Haloa focuses mainly on the “first fruits” of the harvest, partly as a grateful acknowledgement for the benefits the husbandmen received, partly as prayer that the next harvest would be plentiful. The festival was also called Thalysia or Syncomesteria. The festival Haloa took place every year, during the month Poseideon (Ποσειδέων ...
