They are nocturnal, which means they are active at night, hunting for prey. They do not simply attack for the sake of it. They hide during the day and will only sting if provoked.
The stinger is located at the tip of their tail, which injects poison into the insect it’s feeding on, helping them to pin their prey down until it dies and they can eat. They have sharp pincers, which they use to hold onto and pull their prey apart.
These are shy and nervous scorpions that would much rather run away from danger than face it. They will only sting if provoked and they have nowhere to escape.
