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.
Thelyphonida is an arachnid order comprising invertebrates commonly known as whip scorpions or vinegaroons. They are often called uropygids in the scientific community based on an alternative name for the order, Uropygi. 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.
The Kinosternidae are a family of mostly small turtles that includes the mud turtles and musk turtles. The family contains 25 species within four genera, but taxonomic reclassification is an ongoing process, so many sources vary on the exact numbers of species and subspecies. They inhabit slow-moving bodies of water, often with soft, muddy bottoms and abundant vegetation.
Echis carinatus is a venomous viper species found in parts of the Middle East and Central Asia, and especially the Indian subcontinent. It is the smallest member of the big four snakes that are responsible for causing the most snakebite cases and deaths, due to various factors including their frequent occurrence in highly populated regions, and their inconspicuous nature. Five subspecies are currently recognized, including the nominate subspecies described here.
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.
Opistophthalmus boehmi, the yellow forest scorpion, is a small scorpion native to southern Africa. It is a burrowing scorpion which can create intricate tunnels and spend days buried at the bottom of its lair.
Hadrurus spadix is a large 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.
Hadrurus arizonensis, the giant desert hairy scorpion, giant hairy scorpion, or Arizona Desert hairy scorpion is the largest scorpion in North America, and one of the 8–9 species of Hadrurus in the United States, attaining a length of 14 cm (5.5 in). Its large size allows it to feed easily on other scorpions and a variety of other prey, including lizards and snakes. They have also been known to take down or fight with the Giant Desert Centipedes of Arizona. This species is usually yellow with a dark top and has crab-like pincers. It gets its common names from the brown hairs that cover its body. These hairs help it to detect vibration in the soil. A similar species is the Hadrurus spadix.
Parabuthus transvaalicus is a species of venomous scorpion from semi-arid parts of southern Africa.
Opistophthalmus is a genus of scorpions known commonly as burrowing scorpions, tricolored scorpions, serkets, or hissing scorpions. They are found predominantly in southern Africa. They are known for making deep and elaborate burrows.
