Toxicity to pets
There are over 1500 species of scorpions throughout the world (except Antarctica). In North America, only one species is considered venomous: the Arizona bark scorpion (Centruroides exilicauda, formerly Centruroides sculpturatus). This scorpion is approximately 7-8 cm in length, light brown in color, and nocturnal. The venom in scorpions is a mixture of neurotoxins, proteins, and polypeptides. When dogs or cats are bitten by scorpions, typical clinical signs include drooling, localized pain, itchiness, and redness to the bite area. Rarely, more severe signs of an abnormal heart rate, abnormal blood pressure, dilated pupils, tremors, walking drunk, and abnormal eye movement may be seen. The use of antivenom is controversial, and generally symptomatic supportive care is of benefit.
