Xenesthis Immanis
''Xenesthis immanis'', the Colombian lesser black tarantula, is a terrestrial bird spider (tarantula) originating from Colombia. It is a relatively large spider with a body length reaching 6–7 cm and a length width reaching 19-22 cm. It frequently displays a commensal or mutualistic relationship with the microhylid frog '' Chiasmocleis ventrimaculata''.Reginald B. Cocroft and Keith Hambler"Observations on a Commensal Relationship of the Microhylid Frog ''Chiasmocleis ventrimaculata'' and the Burrowing Theraphosid Spider ''Xenesthis immanis'' in Southeastern Peru" ''Biotropica'' Vol. 21 No. 1 (1989) The relationship described is one where the spider may protect the frog and its eggs from predators while the frog protects the spider's eggs from ants. It has also been observed closely associating with ''Hamptophryne boliviana ''Hamptophryne boliviana'', also known as the Bolivian bleating frog or Amazon sheep frog, is a species of frogs in the family Microhylidae.

Anton Ausserer
Anton Ausserer (5 July 184320 July 1889)Maurer, Ferdinand: ''Nachruf an Dr. Anton Ausserer.'' Programm des kk. acad. Gymnasiums in Grätz. Graz 1890 was an Austrian naturalist specialising in spiders.Bonnet, Pierre: Bibliographia aranearum, Les frères Doularoude. Toulouse 1945 His father died when he was a youth, and he and his family suffered much economic hardship, but he was supported and encouraged by Camill Heller, professor of Zoology and Comparative Anatomy at the University of Innsbruck. Life and career Anton Ausserer was one of five children of a gunsmith in Bozen (Bolzano), Tyrol). His teachers noticed his talent at a young age, so they encouraged his father to send him to the Franciscan high school. There he had Vincenz Maria Gredler, a pioneer of zoological research in Tyrol, as his teacher. Already at this time he showed a great interest in science. At the age of 15 he became an orphan. During high school and university he had to struggle with bitter economic hards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarantula
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. , 1,040 species have been identified, with 156 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes. Overview Like all arthropods, the tarantula is an invertebrate that relies on an exoskeleton for muscular support.Pomeroy, R. (2014, February 4). Pub.

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization. Spanish is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutualism (biology)
Mutualism describes the ecological interaction between two or more species where each species has a net benefit. Mutualism is a common type of ecological interaction. Prominent examples include most vascular plants engaged in mutualistic interactions with mycorrhizae, flowering plants being pollinated by animals, vascular plants being dispersed by animals, and corals with zooxanthellae, among many others. Mutualism can be contrasted with interspecific competition, in which each species experiences ''reduced'' fitness, and exploitation, or parasitism, in which one species benefits at the expense of the other. The term ''mutualism'' was introduced by Pierre-Joseph van Beneden in his 1876 book ''Animal Parasites and Messmates'' to mean "mutual aid among species". Mutualism is often conflated with two other types of ecological phenomena: cooperation and symbiosis. Cooperation most commonly refers to increases in fitness through within-species (intraspecific) interactions, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiasmocleis Ventrimaculata
''Chiasmocleis ventrimaculata'', also known as the dotted humming frog, is a species of frog in the family Microhylidae. It is found in Bolivia, Brazil, Colombia, Ecuador, and Peru. Its natural habitats are subtropical or tropical moist lowland forests, swamps, and intermittent freshwater marshes. Description The ''Chiasmocleis ventrimaculata'' is a small nocturnal frog of a snout - vent size of approximately 2 cm. The ''Chiasmocleis ventrimaculata'' lack webbing on the hind foot. Furthermore, the ''Chiasmocleis ventrimaculata'' has heads that are more narrow and pointed and bodies that are slender as well. These frogs prefer to remain underground during the day and emerge after dusk alongside of their spider hosts and forage the surrounding areas. These frogs do not appear to be territorial, often several frogs ranging from 1 to 4, can be seen emerging from a tarantula’s burrow. As tadpoles, they are typically around 17 mm in length and a body length of 7 mm. Their bodies ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamptophryne Boliviana
''Hamptophryne boliviana'', also known as the Bolivian bleating frog or Amazon sheep frog, is a species of frogs in the family Microhylidae. It is found in the northern and western sides of the Amazon basin in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Genetic analysis suggests hidden diversity within the nominal species. Description Adult males from Peru measure and adult females in snout–vent length; some populations might be smaller in body size. The body is moderately robust. The fingers and toes bear distinct terminal discs; lateral fringes and webbing are not present. The dorsum is tan with a large, brown mid-dorsal blotch. There is usually a faint, creamy white mid-dorsal stripe. The flanks, sides of the head, and concealed surfaces of the limbs are dark brown. Males have dark brown throat. The belly and ventral surfaces of the hind limbs are creamy white with brown spots or reticulations. The iris is pale bronze and has f ...

Arthropods Of Colombia
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-lik ...
