They use their pincers to dig these burrows, some up to 1m deep. These burrows are often also used as a trap, into which insects accidentally fall. Because they are so secretive and mainly active at night, scorpions don't have elaborate camouflage. In the daytime, they hide in their burrows, in crevices or hang under rocks or branches. Scorpions that live on the dark rainforest floor may be active during the day.
All scorpions are venomous.
Scorpion venom is a cocktail of toxins, each scorpion species has a unique mixture designed for a particular prey or predator. Most venom is particularly toxic to insects, some to mammals probably because mammals are an important predator. Scorpions can control how much venom is injected in a sting. Scorpions with small, weak pincers tend to have more potent venom and sting repeatedly. Large scorpions may not sting small prey but just use their pincers to crush or rip up the prey alive.
