Looks how to spot one
Hard, glossy exoskeleton
One of the world's biggest scorpions, with a glossy black body that can show a greenish metallic sheen, and large, bumpy, reddish-black claws. Like other scorpions, it glows blue-green under ultraviolet light.12
Personality what they are like
Known as one of the calmest, most tolerant scorpions. It is shy by nature, active mainly at night, and usually backs off rather than defending itself. Adults rely on their big claws rather than their sting to hold prey.12
Daily activity how busy a day looks
Nocturnal, burrowing and fairly slow. It likes to dig and hide under bark or in burrows during the day and come out to hunt after dark.23
Grooming and care the hands-on bits
Mist the substrate surface every day or two without making it soggy, and feed at night. The Amateur Entomologists' Society recommends avoiding handling; if it must be moved, use soft-tipped forceps.3
Home where they are happiest
A warm, humid forest-style terrarium with a deep layer (about 6-7 cm) of peat-free compost, topped with bark chips and hides. Keep a warm area of about 25 C using a heat mat under one third of the base.3
Food basics what goes in the bowl
An insectivore. In the wild termites are its main food. In captivity a large adult often eats 2-3 adult crickets a week.123
Company who they like around
Wild emperor scorpions can live in colonies of up to about 15, and most scorpions can be kept in small groups with enough hides.23
The story where it all began
C. L. Koch described the species in 1842. It became one of the most popular pet scorpions thanks to its calm nature and size, and it is now listed by CITES so that the trade in wild-caught animals is monitored.1
