Cratera Paraitinga
''Cratera paraitinga'' is a species of land planarian belonging to the subfamily Geoplaninae. It is known from specimens found in the Boracéia Biological Station in Brazil. Description ''Cratera paraitinga'' is a flatworm that can reach up to 76 mm in length and 7 mm in width. The body is slightly lanceolate, with a rounded front tip. The body is widest at the pharynx, narrowing gradually towards the front and abruptly towards the back tip. The dorsal side of the body has a melon yellow median stripe that's bordered on either side by a jet black stripe; the stripes have a white band on the outside. The body margins are jet black. The front margins of the body fade into a carmine red color. The ventral side is a grey white color that fades into orange brown at the front of the body.Araujo, A. P. G.; Carbayo, F.; Riutort, M.; Álvarez-Presas, M. (2020). Five new pseudocryptic land planarian species of ''Cratera'' (Platyhelminthes: Tricladida) unveiled through integrative taxonom ...

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. 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). ''Index to the species of the family Geoplanidae (Turbellaria, Tricladida, Terricola) Part I: Geoplaninae.'' 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 and cannot be considered a synapomorphy of the group. Some characteristics have also been ...

Boracéia Biological Station
The Boracéia Biological Station ( pt, Estação Biológica de Boracéia) is field research center of the Museum of Zoology of the University of São Paulo in Salesópolis in the state of São Paulo. Its mission is to carry out biological research in zoology and botany on the Atlantic Forest (Mata Atlântica) of the São Paulo region. The biological station covers within the municipality of Salesópolis and is located from the city of São Paulo. The Boracéia Biological Station was established on March 16, 1954 under Decree-Law 23 198 of 1954. The center traces its history to 1938 with the establishment of the Quina Experimental Station of the Agronomical Institute of Campinas. The station studied the cultivation of quina, a medicinal plant known as sources for quinine. Quina was grown at the institute until 1952. The biological station is located within a larger protective water reserve maintained by Sabesp, a water and waste management owned by the State of São Paulo. The ...

Brazil
Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo. The federation is composed of the union of the 26 states and the Federal District. It is the largest country to have Portuguese as an official language and the only one in the Americas; one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world; and the most populous Roman Catholic-majority country. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other countries and territories in South America except Ecuador and Chile and covers roughly half of the continent's land area. Its Amazon basin includes a vast tropical forest, ho ...

Pharynx
The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the oesophagus and trachea (the tubes going down to the stomach and the lungs). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food and air to the esophagus and larynx respectively. The flap of cartilage called the epiglottis stops food from entering the larynx. In humans, the pharynx is part of the digestive system and the conducting zone of the respiratory system. (The conducting zone—which also includes the nostrils of the nose, the larynx, trachea, bronchi, and bronchioles—filters, warms and moistens air and conducts it into the lungs). The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx. It is also important in vocalization. In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen. They are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salesópolis
Salesópolis is a municipality in the state of São Paulo in Brazil. It is part of the Metropolitan Region of São Paulo. The population is 17,252 (2020 est.) in an area of 424.997 km². Salesópolis sits at an elevation of . It is noted for being the source of the Tietê River. Salesópolis was founded in the 19th century as São José do Paraitinga, and later became the parish of Santana de Mogi das Cruzes in 1838. The parish was elevated to municipality status on March 24, 1857, but renamed Salesópolis in 1905 after a visit of the president of Brazil, Campos Sales (1841-1913). The Tietê River flows in the northern part of the municipality, and much of the southern part of the municipality is mountainous, heavily forested, and inaccessible. The Atlantic Forest (Mata Atlântica) of Salesópolis were largely destroyed in the late 19th and early 20th century, but 96 ha of the municipality are now protected as part of the Boracéia Biological Station, a unit of the Museum of ...

Animals Described In 2020
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 echinoderms a ...
