Grammostola Grossa
''Grammostola grossa'', the Guarani giant tarantula, is a tarantula that, like all species of the genus ''Grammostola'', is native to South America. It occurs in Brazil, Paraguay, Uruguay and Argentina. The species was described in 1871 by the Austrian Anton Ausserer, but only received its trivial name Guarani giant Tarantula in the 21st century by the anthropologist Nils Seethaler. The name was given to the spider because of its abundance in the Guarani settlement area, whose agriculture and the associated clearing of forests extended its range. Characteristics With a body length of up to 8 cm it is one of the larger representatives of tarantulas. It has a black-brown ground colour and brown hairs. Like all ''Grammostola'' species, it has a clearly visible stinging hair on the abdomen (Opisthosoma), so it belongs to the so-called "bombardier spiders", which can defend themselves with stinging hairs. Females are said to be able to live up to 25 years.Peter Klaas: ''Vogelspinnen ... [...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.

Grammostola Anthracina
''Grammostola anthracina'' is a species of spider belonging to the family Theraphosidae (tarantulas). It is found in Uruguay, Paraguay, Brazil, and Argentina. Taxonomy The species was first described in 1842 by Carl Ludwig Koch as ''Mygale anthracina''. In 1850, he transferred it to his subgenus ''Eurypelma'' using the name ''(Mygale) Eurypelma anthracina'', although ''Eurypelma'' was treated as a valid genus by later authors. (As the Greek word ''pelma'' is neuter, the correct form of the species name in this combination is ''anthracinum'', as used by Carl Friedrich Roewer in 1942, for example.) Much later, Robert Raven (1985) synonymized ''Eurypelma'' with ''Avicularia'' (though this had previously been done by Thorell 1870 it had been ignored), implicitly transferring the species to this latter genus ''Avicularia''. A re-examination of the holotype in 2011 suggested that it actually belonged to the genus '' Grammostola''. Description ''Grammostola anthracina'' is chara ...

Grammostola Pulchripes
One of the larger species of tarantula, the Chaco golden knee (''Grammostola pulchripes''), formerly known as ''Grammostola aureostriata'', can be expected to reach between 20 and 22 cm (8.5 in). Name The former (and very commonly used) species name, ''aureostriata'', is derived from Latin ''aureus'' "golden" and ''striatus'' "striped". The currently used species name, "pulchripes," is derived from Latin "pulchra", meaning "beautiful", and "pes", meaning "foot". Description and behavior The Chaco golden knee is a large tarantula, being able to reach between 7 and 8 inches in legspan (17.8-20.3 cm). Being a terrestrial tarantula, it has a heavy body. Mature males have longer legs and smaller bodies than females, and they possess tibial hooks or apophyses to hold back a female's fangs during mating. Males also possess modified pedipalps to insert sperm into the female's genital operculum. It exhibits a multitude of colors, with bright yellowish leg stripes, dark bl ...

Jaw Claw
The jaw is any opposable articulated structure at the entrance of the mouth, typically used for grasping and manipulating food. The term ''jaws'' is also broadly applied to the whole of the structures constituting the vault of the mouth and serving to open and close it and is part of the body plan of humans and most animals. Arthropods In arthropods, the jaws are chitinous and oppose laterally, and may consist of '' mandibles'' or '' chelicerae''. These jaws are often composed of numerous mouthparts. Their function is fundamentally for food acquisition, conveyance to the mouth, and/or initial processing (''mastication'' or ''chewing''). Many mouthparts and associate structures (such as pedipalps) are modified legs. Vertebrates In most vertebrates, the jaws are bony or cartilaginous and oppose vertically, comprising an ''upper jaw'' and a ''lower jaw''. The vertebrate jaw is derived from the most anterior two pharyngeal arches supporting the gills, and usually bears n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
