Geoplana Paranapiacaba
''Geoplana paranapiacaba'' is a species of land planarian belonging to the subfamily Geoplaninae. It is known from specimens found in the Paranapiacaba district of Santo André, Brazil. Description ''Geoplana paranapiacaba'' is a flatworm around 50 mm in length and 4 mm in width. The body has parallel margins; the front tip is rounded and the back tip is pointed. The dorsal side has an orange-ochre stripe running down the middle, bounded on each side by a black line; the line is bordered by a broader white line, which is in turn bordered by a black stripe, which is then bordered by a grey stripe with white mottling. A marginal thin black line borders the grey stripe. The ventral side is a whitish color with blackish margins.Ana Laura Almeida and others, ‘Endless forms most beautiful’: taxonomic revision of the planarian ''Geoplana vaginuloides'' (Darwin, 1844) and discovery of numerous congeners (Platyhelminthes: Tricladida), ''Zoological Journal of the Linnean Soci ...

Land Planarian
Geoplanidae is a family of flatworms known commonly as land planarians or land flatworms. These flatworms are mainly predators of other invertebrates, which they hunt, attack and capture using physical force and the adhesive and digestive properties of their mucus. They lack water-retaining mechanisms and are therefore very sensitive to humidity variations of their environment. Because of their strict ecological requirements, some species have been proposed as indicators of the conservation state of their habitats. They are generally animals with low vagility (dispersal ability) and with very specific habitat requirements, so they can be also used to accurately determine the distribution of biogeographic realms. Today the fauna of these animals is being studied to select conservation priorities in the Atlantic rainforest in Brazil. At the other extreme, one species in this family, '' Platydemus manokwari'' has become an invasive species in both disturbed and wild habitats in the ...

Geoplaninae
Geoplaninae is a subfamily of land planarians endemic to the Neotropical region. Members of this family are sometimes referred to as the Neotropical land planarians. However, one species, '' Obama nungara'' has been introduced in Europe. Description The subfamily Geoplaninae was initially defined by Ogren and Kawakatsu (1990)Ogren, R. E. and Kawakatsu, M. (1990).

Bulletin of Fujis Women's College. 29: 79-166. for land planarians which have a broad creeping sole, mouth in the second half of the body, dorsal testes, subepithelial longitudinal musculature well developed and parenchymal longitudinal musculature absent or not well developed. The eyes contour the anterior region in a single row and posteriorly form several rows, which may spread onto the dorsum, and extend to the posterior end of the body. However, most, if not all, of these characteristics are not exclusive a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paranapiacaba
Paranapiacaba is a district of the municipality of Santo André in the Brazilian São Paulo (state), state of São Paulo. It is located approximately by road southeast of the centre of the city of São Paulo (city), São Paulo, and about east of Rio Grande da Serra. The word ''paranapiacaba'' means "where you will find the sea" in Tupi language, Tupi. Paranapiacaba was established as a company town for the employees of São Paulo Railway, a privately owned British railway company. A large industrial complex, which the district is known for, lies off the main road from Rio Grande da Serra, on the way into the main village. The growth of this centre was facilitated by the railway, transporting cargo and people from São Paulo Interior to the port of Santos, São Paulo, Santos. The village design has been characterized as being Panopticism, panoptic. Geography The village is located on a slope opposite Santo André, approximately by road southeast of the centre of the city of São ...

Ejaculatory Duct
The ejaculatory ducts (''ductus ejaculatorii'') are paired structures in the male reproductive system. Each ejaculatory duct is formed by the union of the vas deferens with the Excretory duct of seminal gland, duct of the seminal vesicle. They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus. Function Ejaculation Ejaculation occurs in two stages, the emission stage and the expulsion stage.Rathus, S. A., Nevid, J. S., Fichner-Rathus, L., Herold, E. S. (2010). ''Human Sexuality in a World of Diversity''. Pearsons Education Canada, Pearson Canada Inc. Toronto, ON. The emission stage involves the workings of several structures of the ejaculatory duct; contractions of the prostate gland, the seminal vesicles, the bulbourethral gland and the vas deferens push fluids into the prostatic urethra. The semen is stored here until ejacula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Animals Described In 2019
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia (). With few exceptions, animals consume organic material, breathe oxygen, have myocytes and are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million living animal species have been described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology, and the study of animal behaviour is known as ethology. The animal kingdom is divided into five major clades, namely Porifera, Ctenophora, Placozoa, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Atlantic Forest
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as ''Biota (ecology), biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontology, Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology '':wikt:fauna, Fauna'' comes from the name Fauna (deity), Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan (god), Pan, and ''panis'' is the Modern Greek equivalent of fauna (πα� ...
