Scorpion "Fun Facts"

Fun Facts:

1.The Arizona bark scorpion, is a small light brown scorpion common to the southwest United States. The range of the scorpion is the Sonoran Desert, though less toxic relatives of the scorpion are located throughout the Southern US.

2.An adult male can reach 8 cm in length (3.14 inches), while a female is slightly smaller, with a maximum length of 7 cm (2.75 inches).

3.
The bark scorpion is nocturnal, prefers to ambush its prey, and usually feeds on crickets and roaches.

4. Bark scorpions are eaten by a wide variety of animals such as birds, reptiles, and other invertebrates. Some examples include spiders, snakes, peccaries, rodents, and other scorpions.
5. Arizona bark scorpions have a gestation period of several months, are born live, and are gently guided onto their mother's back. The female usually gives birth to between 25-35 young, and the young will remain with their mother until their first molt, up to 3 weeks after birth. Arizona bark scorpions may live up to 6 years.

6.While nearly all scorpions are solitary, the Arizona bark scorpion is a rare exception: during winter, packs of 20 to 30 scorpions can congregate. (How lucky is that??)

7.Bark scorpions, like most other scorpions, are incredibly resilient. Lab experiments have frozen the scorpions for weeks, and after being thawed, the scorpions emerged unharmed. During US nuclear testing, scorpions, along with cockroaches and lizards, were found near ground zero with no recorded adverse effects.

8. The bark scorpion is particularly well adapted to the desert: layers of fat on its exoskeleton make it resistant to water loss. Nevertheless, bark scorpions hide during the heat of the day, typically under rocks, wood piles, or tree bark. Bark scorpions do not burrow, and are commonly found in homes, requiring only 1/16th of an inch for entry.

9. Centuroides scorpions are unusual in that they are the only genus in the southwest that can climb walls, trees, and other objects with a sufficiently rough surface. Bark scorpions practice negative geotaxis, preferring an upside down orientation, which often results in people being stung due to the scorpion being on the underside of an object.

10. The bark scorpion is the most venomous scorpion in North America, and its venom can cause severe pain (coupled with numbness and tingling) in adult humans, typically lasting between 24 to 72 hours. Temporary dysfunction in the area stung is common; e.g. a hand or possibly arm can be immobilized or experience convulsions. It also may cause the loss of breath for a short period of time. Due to the extreme pain induced, many victims describe sensations of electrical jolts after envenomation.

Which is your favorite "Fun Fact"? They are all pretty AWESOME don't you think?
