Angaria Loebbeckei
''Angaria loebbeckei'' is a species of sea snail, a marine gastropod mollusk in the family Angariidae. It was discovered and described in 2022 based on only four specimens, which are part of both private and museum collections. In honour of the shell collector Theodor Löbbecke, who would have celebrated its 200th birthday in 2021, the new species was named after him. The holotype is preserved in the Aquazoo Löbbecke Museum in Düsseldorf, Germany, which houses the collection started by Theodor Löbbecke. "Günther, R. (2022). Angaria loebbeckei n. sp. - a new species from an old collection (Gastropoda: Angariidae). Conchylia. 52(3-4): 61-66. page(s): 61, pls 1-2 Description ''Angaria loebbeckei'' is a rather small snail growing up to 25 to 30 mm. Günther (2022) describes the spire of the shell as quite low to moderately high. The shoulder of the shell is straight or wavy/knobby. The spines are variable from totally absent to long and straight. The colour is also rather v ... [...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, |
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.

Mollusk
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 ...

Theodor Löbbecke
Carl Heinrich Wilhelm Theodor Löbbecke (March 4, 1821, Hückeswagen — January 18, 1901, Düsseldorf) was a German pharmacist, malacologist and the founder of the collections of the Aquazoo Löbbecke Museum in Düsseldorf. Jochen Reiter (Ed.) ''Aquazoo Löbbecke Museum: Düsseldorfs exotische Perle'', Droste-Verlag, 192 pages, 2018, His collection is still preserved by the institution and rich in type material of several mollusc species, such as the Chicoreus loebbeckei but also contains many template individuals depicted in early malacological literature. Life Löbbecke left the school in Elberfeld in 1837 and spent the next six years training as a pharmacist. In 1843 he studied for a year at the Humboldt University of Berlin, University of Berlin, after which he was licensed to become a first-class pharmacist. Around 1846, Löbbecke took over the Einhorn pharmacy in Duisburg, at which time he also began to build up his collection. The physician, natural scientist and natura ...

Aquazoo Löbbecke Museum
The Aquazoo Löbbecke Museum unites Zoo, Natural History Museum and Aquarium in one institution under the administration of the city of Düsseldorf. It was opened in 1987 in the North Park under the name "Löbbecke-Museum + Aquazoo" (there have been precursor institutions on different locations in Düsseldorf though). On an area of about 2000 square meters, around 500 animal species are exhibited in 25 themed rooms in aquariums, terrariums and a tropical hall. Moreover, the exhibition includes 1,400 natural history exhibits, models and interactive stations. With about 400.000 visitors per year, the Aquazoo Löbbecke Museum has been by far the most visited cultural institution in the city of Düsseldorf for many years. The name of the institution refers to Theodor Löbbecke who laid the foundation of the natural history collection by collecting sea shells.Jochen Reiter (Ed.)

Düsseldorf
Düsseldorf ( , , ; often in English sources; Low Franconian and Ripuarian: ''Düsseldörp'' ; archaic nl, Dusseldorp ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state and the seventh-largest city in Germany, with a population of 617,280. Düsseldorf is located at the confluence of two rivers: the Rhine and the Düssel, a small tributary. The ''-dorf'' suffix means "village" in German (English cognate: ''thorp''); its use is unusual for a settlement as large as Düsseldorf. Most of the city lies on the right bank of the Rhine. Düsseldorf lies in the centre of both the Rhine-Ruhr and the Rhineland Metropolitan Region. It neighbours the Cologne Bonn Region to the south and the Ruhr to the north. It is the largest city in the German Low Franconian dialect area (closely related to Dutch). Mercer's 2012 Quality of Living survey ranked Düsseldorf the sixth most livable city in the world.
