Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies.
The house mouse is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus Mus. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity.
The emperor scorpion(Pandinus imperator) is a species of scorpion native to rainforests and savannas in West Africa. It is one of the largest scorpions in the world and lives for 6–8 years. Its body is black, but like other scorpions it glows pastel green or blue under ultraviolet light. It is a popular species in the pet trade, and is protected by CITES to prevent over-collecting that might affect the species' survival.
The Arizona bark scorpion is a small light brown scorpion common to the Sonoran Desert in the southwestern United States and northwestern Mexico. An adult male can reach 8 cm in length (3.14 inches), while a female is slightly smaller, with a maximum length of 7 cm (2.75 inches).
The Neotominae are a subfamily of the family Cricetidae. They consist of four tribes, 16 genera, and many species of New World rats and mice, predominantly found in North America. Among them are the well-known deer mice, white-footed mice, packrats, and grasshopper mice.
A fancy mouse is a domesticated form of the house mouse, one of many species of mice, usually kept as a type of pocket pet. Fancy mice have also been specially bred for exhibiting, with shows being held internationally. A pet mouse is inexpensive compared to larger pets, and even many other pet rodents, but mice are comparatively short-lived: typically only 2 to 3 years.
The wood mouse is a murid rodent native to Europe and northwestern Africa. It is closely related to the yellow-necked mouse but differs in that it has no band of yellow fur around the neck, has slightly smaller ears, and is usually slightly smaller overall: around 90 mm (3.54 in) in length and 23 g in weight. It is found across most of Europe and is a very common and widespread species, is commensal with people and is sometimes considered a pest. Other common names are long-tailed field mouse, field mouse, common field mouse, and European wood mouse. This species is a known potential carrier of the Dobrava sequence of hantavirus which affects humans and may pose serious risks to human health.
Peromyscus maniculatus is a rodent native to eastern North America. It is most commonly called the eastern deer mouse; when formerly grouped with the western deer mouse, it was referred to as the North American deermouse and is fairly widespread across most of North America east of the Mississippi River, with the major exception being the lowland southeastern United States.
The white-tailed antelope squirrel is a diurnal species of ground squirrel, scientifically classified in the order Rodentia and family Sciuridae, found in arid regions of the southwestern United States and the Baja California Peninsula of northwestern Mexico.
Hadrurus arizonensis, the giant desert hairy scorpion, giant hairy scorpion, or Arizona Desert hairy scorpion is a large scorpion found in North America.
The striped bark scorpion is an extremely common scorpion found throughout the midsection of the United States and northern Mexico. It is perhaps the most frequently encountered scorpion in the U.S.
The Algerian mouse, also known as the western Mediterranean mouse, is a wild species of mouse closely related to the house mouse, native to open habitats around the western Mediterranean.
The northern grasshopper mouse is a North American carnivorous rodent of the family Cricetidae. It ranges over much of the western part of the continent, from southern Saskatchewan and central Washington to Tamaulipas in northeast Mexico.
Many species of arthropods can bite or sting human beings. These bites and stings generally occur as a defense mechanism or during normal arthropod feeding. While most cases cause self-limited irritation, medically relevant complications include envenomation, allergic reactions, and transmission of vector-borne diseases.
Grasshopper mice are rodents of the genus Onychomys, occurring in North America. They feed on insects and other arthropods.
Androctonus bicolor, the black fat-tailed scorpion, is a scorpion species of the family Buthidae. It is black in color and can grow up to 8 cm. Black fat-tailed scorpions come from the family Buthidae, which is the largest of the scorpion family. They can be identified by their hefty physique. They tend to move very fast, and are of an aggressive nature. Black fat–tailed scorpions can live for up to 5 years. Adults can reach up to 40-60 millimeters, 80 millimeters being the maximum. These scorpions typically possess black and brown coloration. These scorpions enjoy making scrapes with wood and rocks, and are nocturnal, thus they hide in crevices or certain objects during the day. They stay in shade to retain moisture in their bodies, as they are susceptible to losing moisture due to their environmental preference.
Dinoponera is a strictly South American genus of ant in the subfamily Ponerinae, commonly called tocandiras or giant Amazonian ants. These ants are generally less well known than Paraponera clavata, the bullet ant, yet Dinoponera females may surpass 3–4 cm (1.2–1.6 in) in total body length, making them among the largest ants in the world.
Centruroides gracilis is a species of scorpion in the family Buthidae, the bark scorpions. Its common names include Florida bark scorpion, brown bark scorpion, and slender brown scorpion. In Cuba it is known as alacran prieto and alacran azul. Contrary to one of its common names, it is not actually native to Florida in the United States. It is native to northern parts of the middle Americas, including Mexico, Guatemala, Belize, and Honduras. It is present in other parts as an introduced species, including Cuba, Panama, Colombia, Ecuador, Jamaica, and Florida in the United States. It is also introduced in parts of Africa, including Cameroon and Gabon, as well as the island of Tenerife
Leiurus abdullahbayrami is a species of scorpion in the family Buthidae. Its venom is highly toxic to humans, but can be used in medical development.
Hemiscorpius lepturus is a species of scorpion in the family Hemiscorpiidae. It is found in deserts of the Middle East, especially in southern Iraq and Iran, where it is sometimes referred to as the "Gadim scorpion". These scorpions have long, thin tails and wide bodies and grow to 8 cm (3.1 in) in males and 5.5 cm (2.2 in) in females, allowing them to live in tight rock crevices. They are fairly solitary creatures. H. lepturus has mainly been studied to discover the components and effects of its venom, which is highly lethal and is responsible for most deaths due to scorpion sting in the Iran area. H. lepturus is the only scorpion not in the family Buthidae that is potentially lethal to humans; the Buthidae family is the largest and most abundant family of scorpions, containing many highly venomous species.
