Mastigoproctus Giganteus
''Mastigoproctus giganteus'', the giant whip scorpion, also called the giant vinegaroon or grampus, is a species of whip scorpions in the family Thelyphonidae. Description This species can grow to be long, excluding the tail. They have six legs used for movement, two long antenniform front legs that they use to feel around for prey and detect vibrations, and two large pedipalps modified into claws that they use to crush their prey. They have a long, thin, whip-like tail, the origin of the common name whipscorpion. From the base of this tail they can spray a substance composed of 85% acetic acid in order to defend themselves. Acetic acid is the main component of vinegar, so the spray smells strongly of vinegar, leading to the common name "vinegaroon". ''Mastigoproctus giganteus'' have eight eyes: two in a pair on the front of the head and three on each side of the head. These eyes are very weak, so ''Mastigoproctus giganteus'' navigates mostly by feeling with its long front legs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pangaea
Pangaea or Pangea () was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the equator and surrounded by the superocean Panthalassa and the Paleo-Tethys Ocean, Paleo-Tethys and subsequent Tethys Ocean, Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists. Origin of the concept The name "Pangaea" is derived from Ancient Greek ''pan'' (, "all, entire, whole") and ''Gaia (mythology), Gaia'' or Gaea (, "Mother goddess, Mother Earth, land"). The concept that the continents once formed a contiguous land mass was hypothesised, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Whip Scorpions
Thelyphonida is an arachnid order comprising invertebrates commonly known as whip scorpions or vinegaroons (also spelled vinegarroons and vinegarones). They are often called uropygids in the scientific community based on an alternative name for the order, Uropygi (which may then also include the order Schizomida). The name "whip scorpion" refers to their resemblance to true scorpions and possession of a whiplike tail, and "vinegaroon" refers to their ability when attacked to discharge an offensive, vinegar-smelling liquid, which contains acetic acid. Taxonomy Carl Linnaeus first described a whip scorpion in 1758, although he did not distinguish it from what are now regarded as different kinds of arachnid, calling it ''Phalangium caudatum''. ''Phalangium'' is now used as a name for a genus of harvestmen (Opiliones). In 1802, Pierre André Latreille was the first to use a genus name solely for whip scorpions, namely ''Thelyphonus''. Latreille later explained the name as meaning " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theraphosa Blondi MHNT
''Theraphosa'' is a genus of South American tarantulas that was first described by Tamerlan Thorell in 1870. The Theraphosa spiders are some of the largest known to science, and are usually called Pinkfoot Goliaths in english. it contains three species, found in Guyana, Brazil, Venezuela, and Colombia. They stridulate by rubbing setae on their pedipalps and legs. Diagnostic Tarantulas of this genus are characterized by their large size, and the lack of long hairs in the patella and tibia sections of the legs. It can also be further distinguished by the presence of stridulating hairs on the prolateral coxae 1 and 2. Females also own a unique single spermatheca. Behavior This tarantulas are found in holes in the ground, usually abandoned burrows, which they adopt and use as their own. They are usually found near rivers, and eat a great amount of invertebrates and very small vertebrates, such as small frogs and lizards. Species the World Spider Catalog has accepted the foll ...

Araneae
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate ...

Trombidium Holosericeum (white Background)
''Trombidium holosericeum'' is a species of mite in the genus ''Trombidium''. It occurs in Europe, Asia, and North Africa and is commonly confused with other red mite species. Description This species is one of the largest mites in northern temperate zones, with a body length of about ). The soft, brightly red body is covered with fine hairs, giving it a velvety appearance. The small eyes are located on stalks. They have scissor-like chelicerae and their pedipalps are used as touch organs. Its bright red color results from carotenoids, warning predators about the toxicity of the mite (aposematism). Almost nothing is known about the toxic substances used, but they are probably contained within the integument. The specific epithet is derived from Ancient Greek , , "whole" and , , "silken". Biology While adults live freely and are often found wandering about, searching for small animals and insect eggs for food, the larvae try to find a host to attach themselves to, often an inse ...

Harvestmen
The Opiliones (formerly Phalangida) are an order of arachnids colloquially known as harvestmen, harvesters, harvest spiders, or daddy longlegs. , over 6,650 species of harvestmen have been discovered worldwide, although the total number of extant species may exceed 10,000. The order Opiliones includes five suborders: Cyphophthalmi, Eupnoi, Dyspnoi, Laniatores, and Tetrophthalmi, which were named in 2014. Representatives of each extant suborder can be found on all continents except Antarctica. Well-preserved fossils have been found in the 400-million-year-old Rhynie cherts of Scotland, and 305-million-year-old rocks in France. These fossils look surprisingly modern, indicating that their basic body shape developed very early on, and, at least in some taxa, has changed little since that time. Their phylogenetic position within the Arachnida is disputed; their closest relatives may be the mites (Acari) or the Novogenuata (the Scorpiones, Pseudoscorpiones, and Solifugae). Altho ...

Ticks
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In additi ...
