Luteostriata Abundans
''Luteostriata abundans'' is a species of Brazilian land planarian in the subfamily Geoplaninae. It is a common species in human-disturbed areas in Brazil's southernmost state, Rio Grande do Sul. Description ''Luteostriata abundans'' is a small to medium-sized land planarian with an elongate body and parallel margins. The largest specimens have a length of about 60 millimeters or more. The dorsum has a yellow tinge, varying from cream to dark yellow or light brown and is marked by seven longitudinal dark brown to black stripes. The ventral side is cream. The numerous eyes are very small and hardly visible to the naked eye. They are distributed marginally on the first millimeters of the body and posteriorly become dorsal, covering the two most external stripes on each side. The eyes that cover the stripes are surrounded by halos, zones without pigmentation, which may be perceived as small clear dots. Distribution ''Luteostriata abundans'' is found in human-disturbed area ... [...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 Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laboratory
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data ...

Porto Alegre was founded in 1769 by Manuel Jorge Gomes de Sepúlveda, who used the pseudonym José Marcelino de Figueiredo to hide his identity; but the official date is 1772 with the act signed by Immigration to Brazil, immigrants from the Azores, Portugal. The city lies on the eastern bank of the Guaíba Lake, where five rivers converge to form the Lagoa dos Patos, a giant freshwater lagoon navigable by even the largest of ships. This five-river junction has become an important alluvial port as well as a chief industrial and commercial center ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luteostriata Abundans Eating Woodlouse
''Luteostriata'' is a genus of land planarians from Brazil characterized by a yellow body with dark longitudinal stripes. Description The genus ''Luteostriata'' is characterized by the presence of a cephalic retractor muscle, which allows those animals to pull their anterior end upwards and backwards. Associated to the muscle are cephalic glands, forming a so-called cephalic musculo-glandular organ in a way similar to the one found in the genera '' Choeradoplana'' and '' Issoca''. The copulatory apparatus has an reversible penis, i.e., there is no permanent penis papilla and the penis is formed during copulation by folds in the male cavity which are pushed outwards. Externally, species in this genus usually have a yellow to light brown dorsal color with a series of longitudinal dark stripes, hence the name ''Luteostriata'', from Latin ''luteus'' (saffron yellow) + ''striatus'' (striped). The anterior end is also usually marked by an orange tinge that posteriorly gradually fade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Grande Do Sul
Rio Grande do Sul (, , ; "Great River of the South") is a state in the southern region of Brazil. It is the fifth-most-populous state and the ninth largest by area.

Robert E
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and '' berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It c ...

Platyhelminthes
The flatworms, flat worms, Platyhelminthes, or platyhelminths (from the Greek πλατύ, ''platy'', meaning "flat" and ἕλμινς (root: ἑλμινθ-), ''helminth-'', meaning "worm") are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates. Unlike other bilaterians, they are acoelomates (having no body cavity), and have no specialized circulatory and respiratory organs, which restricts them to having flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. The digestive cavity has only one opening for both ingestion (intake of nutrients) and egestion (removal of undigested wastes); as a result, the food cannot be processed continuously. In traditional medicinal texts, Platyhelminthes are divided into Turbellaria, which are mostly non-parasitic animals such as planarians, and three entirely parasitic groups: Cestoda, Trematoda and Monogenea; however, since the turbellarians have since been proven not to be monop ...
