At a glance the quick version
Adult body length, including tail
Looks how to spot one
Exoskeleton
The body is divided into a cephalothorax with large pincer-like pedipalps, four pairs of legs, and a segmented abdomen ending in a stinger. The colour is a very pale sandy beige, often appearing slightly translucent, with darker brownish-grey dorsal plates and darker joints on the pedipalps.1
Personality what they are like
Dune scorpions are very skittish, fast-moving and highly defensive. They are aggressive towards other scorpions and will cannibalise each other, so they must be kept alone. They are not suitable for handling and will sting readily if threatened.651
Daily activity how busy a day looks
Nocturnal and fossorial; spends 92-97% of its life in burrows. Emerges at dusk to hunt and mate, typically active for about 4 hours each night. Requires deep, loose sand to dig burrows.1
Grooming and care the hands-on bits
Low maintenance. No grooming needed. Enclosure should be kept bone dry with a small water dish. Monthly light misting can help maintain a slight humidity gradient, but the surface must remain dry. Use long tongs for any maintenance to avoid stings.745
Home where they are happiest
A terrestrial enclosure with a minimum of 20x20x20 cm floor space is recommended. Provide at least 10 cm of sand-dominant substrate (70-90% sand mixed with fine soil or clay) to allow burrowing. Temperature should be 24-28°C (daytime) with a gentle gradient, dropping to 20-22°C at night. Humidity should be low, around 30-40%. Ventilation should be moderate. This species is venomous and should never be handled; keepers are advised to use long tongs. It is legal to keep in most places but check local regulations.3415
Food basics what goes in the bowl
Carnivorous. Feed adults every 10-14 days on live prey such as small crickets, roaches, and occasional mealworms or waxworms. Prey should be offered near the burrow entrance to mimic natural ambush hunting.31
Company who they like around
Strictly solitary. They are highly aggressive and cannibalistic towards other scorpions. Must be housed individually. This species is venomous; its sting is not lethal to humans but has been compared to a hornet sting. Keepers should never handle them.15
The story where it all began
The dune scorpion has been kept in captivity for many years by invertebrate enthusiasts, though it remains less common than some other desert scorpions. Its popularity has grown as keepers appreciate its specialised burrowing lifestyle and striking pale colour. It is considered of medium difficulty to keep, suitable for beginners with proper guidance.46

Owner questions the things everyone asks
How often should I feed my Dune Scorpion?
Feed your adult Dune Scorpion every 10 to 14 days with live prey. Juveniles may need more frequent small meals, but always follow the general rule of offering food near the burrow entrance. Furry Diary's starting plan suggests adjusting based on the scorpion's size and moult stage.31 Furry Diary plan
What does a Dune Scorpion eat, and what should it never eat?
Your scorpion is carnivorous and enjoys live prey like small crickets, roaches, and occasional mealworms or waxworms. Never feed it anything other than appropriate live insects, and avoid prey that is too large or could harm it. Always offer food near the burrow entrance to mimic natural hunting.31
How much space does a Dune Scorpion need?
A minimum floor space of 20x20x20 cm is recommended, with at least 10 cm of deep, loose sand-dominant substrate for burrowing. This gives your scorpion room to dig and feel secure. A larger enclosure is always welcome, but the key is deep substrate.341
What temperature, light or water does a Dune Scorpion need?
Keep the daytime temperature between 24-28°C with a gentle gradient, dropping to 20-22°C at night. Humidity should be low, around 30-40%, and the enclosure bone dry except for a small water dish. No special lighting is needed, as they are nocturnal and fossorial.3417
How often should I clean a Dune Scorpion's home?
Spot clean weekly by removing leftover food and waste, and change the substrate every 6 months. Furry Diary's plan also suggests checking the water dish and humidity every couple of days. Use long tongs for any maintenance to stay safe.745 Furry Diary plan
Can a Dune Scorpion live with others?
No, they are strictly solitary and highly aggressive towards other scorpions, often cannibalising them. Each scorpion must be housed alone. This is a venomous species, so keeping them separate also reduces risk for you.15
How long does a Dune Scorpion live?
With proper care, a Dune Scorpion typically lives between 5 and 7 years. Their lifespan depends on good husbandry, especially stable temperature and a stress-free environment. Enjoy many years with your fascinating pet!1
Can I handle a Dune Scorpion?
No, handling is not recommended as they are very skittish, fast, and will sting readily if threatened. Their sting is compared to a hornet sting, so always use long tongs for any maintenance or feeding. Admire your scorpion from a safe distance.651
