    A Striped Bark Scorpion (Centruroides vittatus). In San Antonio, if you flip over 5 rocks, chances are you'll find two of these guys.

    Scorpions remain sheltered in the daytime and become active at night, which helps with thermoregulation and water balance. Perhaps these scorpions most interesting behavior though, is their elaborate courtship ritual that may last for hours. The two scorpions grasp each other's pincers and jaws and dance back and forth. Finally, the male deposits a sac of sperm on the ground and pulls the female over it. Then, she picks the sac up with a special organ on her abdomen and fertilization occurs.

    The striped scorpion is primarily insectivorous, consuming mostly spiders, centipedes, crickets, flies, beetles, and other small insects. The scorpion stalks its prey mostly at night and depends on its senses of touch and smell. Comblike chemical receptor organs on their undersides contact the ground as they walk, which helps them track prey. Theses scorpions catch their food by grabbing and crushing them with their powerful pinchers. They then bring their tail over their body and sting the victims. The prey jerk compulsively and are paralyzed by the venom. They die in the scorpions' rigid grasp. The scorpions then chew the prey into a semi-liquid state, that they can suck up with their tiny mouths.

    While their stings can be painful to humans, they are not considered dangerous. he sting is very rarely fatal, and even then, death is due to anaphylactic shock.
