Avicularia Variegata
''Avicularia variegata'' is a species of spider in the family Theraphosidae found in Venezuela and Brazil. Previously described as ''Avicularia avicularia variegata'', it is synonymous with ''Avicularia bicegoi''. When sold as pets, various English names have been associated with the scientific names of this species. As ''A. avicularia variegata'', it has been called the grizzled pinktoe. As ''A. bicegoi'', English names often refer to the red hairs on the abdomen of one colour form – Manaus brick-red rump tree spider, brick red pink toe. Taxonomy In 1896, Frederick O. Pickard-Cambridge described spiders he had observed during an expedition to the Amazon basin as the subspecies ''variegata'' of the species ''Avicularia avicularia''. He based the distinction on variations in colour, particularly of the leg hairs (setae), considering them insufficient to justify separation into two species. In 2017, Caroline Fukushima and Rogério Bertani made a detailed study of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Octavius Pickard-Cambridge
Frederick Octavius Pickard-Cambridge (3 November 1860 – 9 February 1905) was an English arachnologist. He is sometimes confused with his uncle, Octavius Pickard-Cambridge (1828–1917), who was also an arachnologist and from whom F. O. Pickard-Cambridge picked up his enthusiasm for the study of spiders. Life F. O. Pickard-Cambridge was born in Warmwell, Dorset, where his father was rector. He became a curate at St Cuthbert's church in Carlisle for a few years after having been educated at Sherborne School and Exeter College, Oxford. He left to become a professional biological illustrator, and in 1894–1895 spent several months in the Amazon as a naturalist on board the SS ''Faraday''. He found much of interest on his voyage and began writing papers in 1896 to describe the spiders he discovered. He had a promising career ahead of him, but this promise was not to be fulfilled. Bristowe, writing in the book ''British Spiders'', 1951, said of this time in F. O. Pic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spermatheca
The spermatheca (pronounced plural: spermathecae ), also called receptaculum seminis (plural: receptacula seminis), is an organ of the female reproductive tract in insects, e.g. ants, bees, some molluscs, oligochaeta worms and certain other invertebrates and vertebrates. Its purpose is to receive and store sperm from the male or, in the case of hermaphrodites, the male component of the body. Spermathecae can sometimes be the site of fertilization when the oocytes are sufficiently developed. Some species of animal have multiple spermathecae. For example, certain species of earthworms have four pairs of spermathecae—one pair each in the 6th, 7th, 8th, and 9th segments. The spermathecae receive and store the spermatozoa of another earthworm during copulation. They are lined with epithelium and are variable in shape: some are thin, heavily coiled tubes, while others are vague outpocketings from the main reproductive tract. It is one of the many variations in sexual repro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avicularia Avicularia
''Avicularia avicularia'', sometimes called the pinktoe tarantula, is a species of tarantula native from Venezuela, Guyana, Suriname, French Guiana and Trinidad and Tobago to Peru, Bolivia and Brazil. This species is sometimes called the Guyana pinktoe, or South American pinktoe. Description The mature pinktoe tarantula has a dark-colored body and pinkish feet, hence its name. Juvenile specimens, however, have pinkish bodies and dark-colored feet and undergo a reversal in their coloration as they approach adulthood at 4–5 years. A fully grown Pinktoe tarantula can grow up to six inches in length. They have a short lifespan, with males living 2–3 years, and females living between 6–9 years. Dimorphism has been shown in the mature stages of males and females, with males having uniformly barbed urticating hairs, while females are found only at the proximal end. Mature males also exhibit a pair of hooks on the last segment of the pedipalps, used during construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon sys ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...
