Alecton Discoidalis
''Alecton discoidalis'' is a species of firefly in the beetle family Lampyridae, commonly known as the Cuban endemic firefly. The larvae of this species are predators on both pulmonate and operculate land snails. ''Alecton discoidalis'' is the type species of the genus ''Alecton''. Distribution ''Alecton'' is the only genus of firefly endemic to Cuba and ''A. discoidalis'' is the best known of the four species in that genus. It is found in the western half of the country. The type locality was described simply as "the island of Cuba". Description ''Alecton discoidalis'' was discovered and described (based on the larva only) by the French naturalist Francis de Laporte de Castelnau in 1833. His type description in French reads as follows: This translates as: Yellow, with the tips of the antennae and the elytra black, with a yellow border which starts a third of the way along the elytra. Biology The fireflies of Cuba have not been extensively studied. Research was underta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operculum (gastropod)
The operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Psyche (entomological Journal)
''Psyche'' is a scientific journal of entomology which was established in 1874 by the Cambridge Entomological Club as a "journal for the publication of biological contributions upon Arthropoda from any competent person". The name of the journal is derived from the Ancient Greek word for butterfly. The journal has been published since 1874 (with gaps from 1886 to 1887, 1995 to 1999, and 2000 to 2007). In 2007 the Club transferred the journal to the Hindawi Publishing Corporation, and it became an open-access journal in 2008, with articles distributed online under the Creative Commons Attribution License. Almost all back issues were scanned and are available online as PDF files. History Samuel Hubbard Scudder proposed to start an "Organ of the Cambridge Entomological Club" at its fourth meeting. When ''Psyche'' began publication, its first editor was B. P. Mann. Its articles concentrated on general anatomy, biological entomology, and to set up a Bibliographic Record of all writin ...

List Of Non-marine Molluscs Of Cuba
The non-marine molluscs of Cuba are a part of the molluscan wildlife of Cuba. Numerous species of non-marine molluscs are found in the wild in Cuba, which is in fact one of the richest places for the malacological fauna in the world, especially in land snails, hosting a high degree of endemism. Cuba has some highly charismatic species of land snails, such as those of the genus '' Polymita'' and '' Liguus''. A total of 42 species of freshwater molluscs occur in Cuba. Introduced species such as ''Tarebia granifera'' and ''Melanoides tuberculata'' are spread throughout the country and might be a threat for endemics and other native snails. History There are many works regarding taxonomic and systematic studies in marine and land molluscs with a fewer number on ecology and distribution. Freshwater molluscs, however, are scarcer and have received less attention. Freshwater molluscs overview A total of 10 (23.8%) out of 42 described freshwater snails and mussels are endemic in ...

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.

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.

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, dogs, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g. frogs and newts). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Terrestrial animals tend to be more developed and intelligent than aquatic animals. Terrestrial classes The term "terrestrial" is typically applied to species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees. There are other less common terms that apply to specific groups of terrestrial animals: *Saxicolous creatures are rock dwelling. "Saxicolous" is derived from t ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

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] |
Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...
