Amplirhagada
''Amplirhagada'' is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. This genus is endemic to the Kimberley region in northwesternmost Western Australia, where it represents the most species-rich genus of land snails.Köhler, F. (2010). Uncovering local endemism in the Kimberley, Western Australia: Description of new species of the genus ''Amplirhagada'' Iredale, 1933 (Pulmonata, Camaenidae). ''Records of the Australian Museum'' 62(2): 217-284. Characteristic features ''Amplirhagada''-species exhibit variable shells ranging from broadly conical to highly turreted in shape. Shells are comparatively large, ranging from about 10 to 25 mm in height and from about 15 to 30 mm in diameter. Shells are often banded but uniformly brown species are also known. The umbilicus is narrowly winding and open, partly or completely concealed by the columellar reflection. Typical features of the genital organs comprise presence of p ...

Alan Solem
George Alan Solem (21 June 1931 – 26 March 1990),Coan E. V., Kabat A. R. & Petit R. E. (2009). ''2,400 years of malacology, 6th ed.'', February 15, 2009, 830 pp. + 32 pp. nnex of Collations American Malacological Society: http://www.malacological.org/publications/2400_malacology.html known professionally as Alan Solem, was an American malacologist, a biologist who studied mollusks. He was one of the most renowned land snail experts of his time and had earned a reputation for his comprehensive revisions of mainly terrestrial pulmonates. He worked on land snails from all regions of the world but became particularly known for his revisions of land snails from Australasia and various Pacific Islands. His 140 academic papers dealt with the snail phylogeny, feeding patterns and reproductive strategies. He named many taxa, amongst them about 350 species of Australian land snails, and several genera.Cameron, R. A. D., B. M. Pokryszko, and F. E. Wells. 2005. Alan Solem's work on the d ...

Camaenidae
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora. These snails occur in a wide variety of habitats in the tropics of Eastern Asia and Australasia. A large American group, which is mainly represented by species from the Caribbean, has, until recently, also been subsumed under the Camaenidae. However, latest molecular phylogenetic studies showed that these species represent a different family, the Pleurodontidae. This molecular study also implies that the Bradybaeninae, previously being treated as a distinct family within the Helicoidea, is a junior synonym of the Camaenidae. Anatomy Camaenid shells are often quite large (25–50 mm), but a number of species also have small shells (<5 mm). Shells reveal a remarkable diversity in shape and colour, which is partly linked with their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Epiphallus
The reproductive system of gastropods (slugs and snails) varies greatly from one group to another within this very large and diverse taxonomic class of animals. Their reproductive strategies also vary greatly, see Mating of gastropods. In many marine gastropods there are separate sexes (male and female); most terrestrial gastropods however are hermaphrodites. Courtship is a part of the behaviour of mating gastropods. In some families of pulmonate land snails, one unusual feature of the reproductive system and reproductive behavior is the creation and utilization of love darts, the throwing of which has been identified as a form of sexual selection. Gastropods are defined as snails and slugs, belonging to a larger group called Molluscs. Gastropods have unique reproductive systems, varying significantly from one taxonomic group to another. They can be separated into three categories: marine, freshwater, and land. Reproducing in marine or freshwater environments makes getting sperm ...

Penial Sheath
In male human anatomy, the foreskin, also known as the prepuce, is the double-layered fold of skin, mucosal and muscular tissue at the distal end of the human penis that covers the glans and the urinary meatus. The foreskin is attached to the glans by an elastic band of tissue, known as the frenulum. The outer skin of the foreskin meets with the inner preputial mucosa at the area of the mucocutaneous junction. The foreskin is mobile, fairly stretchable and sustains the glans in a moist environment. Except for humans, a similar structure, known as penile sheath, appears in the male sexual organs of all primates and the vast majority of mammals. In humans, foreskin length varies widely and coverage of the glans in a flaccid and erect state can also vary. The foreskin is fused to the glans at birth and is generally not retractable in infancy and early childhood. Inability to retract the foreskin in childhood should not be considered a problem unless there are other symptoms. Ret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
