The Arizona bark scorpion (Centruroides sculpturatus, once included in Centruroides exilicauda) 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).[1]

Centruroides exilicauda, the Baja California bark scorpion, is a species of bark scorpion  found in Baja California. It is closely related to the Arizona bark scorpion (Centruroides sculpturatus), but is not considered dangerous. Previously only distinguished by geographic range, the two variants were classified in 1980 as the same species. Subsequently, differences in venom toxicity were recorded, and in 2004, DNA analysis [1] showed them to be separate species. The Baja California bark scorpion is a slender, long-tailed scorpion, and although it is typically sand-colored it appears in darker colors.[2][3]

Leiurus hebraeus is a species of scorpion, a member of the family Buthidae. It was once considered as a subspecies of Leiurus quinquestriatus but recently it was elevated to the rank of a species.[1]

The deathstalker (Leiurus quinquestriatus) is a species of scorpion, a member of the family Buthidae. It is also known as the Palestine yellow scorpion,[1][2][3][4] Omdurman scorpion, and Naqab desert scorpion, as well as by many other colloquial names, which generally originate from the commercial captive trade of the animal. To eliminate confusion, especially important with potentially dangerous species, the scientific name is normally used to refer to them. The name Leiurus quinquestriatus roughly translates into English as "five-striped smooth-tail".[5] In 2014, the subspecies L. q. hebraeus was separated from it and elevated to its own species Leiurus hebraeus.[6] Other species of the genus Leiurus are also often referred to as "deathstalkers". Leiurus quinquestriatus is yellow, and 30–77 millimetres (1.2–3.0 in) long, with an average of 58 mm (2.3 in).[7]

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 six to eight 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.

Hadrurus arizonensis, the giant desert hairy scorpion, giant hairy scorpion, or Arizona Desert hairy scorpion is a large scorpion  found in North America.

Hadrurus spadix is a large (around 15 centimetres (5.9 inches)) scorpion native to the southern deserts of North America. It is a burrowing scorpion which spends a lot of time digging in the sand and enlarging its burrow. A similar species is the giant desert hairy scorpion.

Centruroides is a genus of scorpions of the family Buthidae. Several North American  species are known by the common vernacular name bark scorpion. Numerous species are extensively found throughout the southern United States, Mexico, Central America, the Antilles and northern South America.[1] Some are known for their interesting patterning or large size (among Buthidae); most if not all fluoresce strongly under ultraviolet  illumination, except after moulting. They contain several highly venomous species, and fatalities are known to occur. The venom of the Mexican scorpion Centruroides limpidus limpidus contains the neurotoxins Cll1 and Cll2.

The striped bark scorpion (Centruroides vittatus) 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.

Heterometrus, whose members are also known by the collective vernacular name Asian Forest Scorpion, is a genus of scorpions belonging to the family Scorpionidae. It is distributed widely across tropical and subtropical southeastern Asia, including Indonesia, Brunei, Malaysia, Myanmar, Philippines, Singapore, Cambodia, Laos, Thailand, Vietnam, India (Nicobar Islands, Andaman Islands), and China  (Hainan).[2][3] It is notable for containing some of the largest living species of scorpions.
