Scorpion
Scorpions are not insects, but arachnids related to spiders. They are known for their pinching claws and venomous stingers.
Kingdom: Animalia
Phylum: Arthropoda
Class: Arachnida
Order: Scorpiones
Family: 22 families
Species: Over 2,500 species
Common Name: Scorpion
Most species of scorpion are active at night, or during dusk and dawn. They hide in holes burrowed under rocks, or use burrows made by other animals, during the daylight hours.
They hunt mainly insects, spiders, worms and other invertebrates, though sometimes will prey upon lizards, snakes, or small mammals.
Scorpions themselves are not without predators. Frogs, lizards and snakes, birds, and mammals all prey on scorpions. Meerkats are particularly good at hunting scorpions, and will bite off the scorpion’s tail to avoid being stung. Certain other predators of scorpions are immune to their venom entirely.
Male and female scorpions often engage in a courtship “dance” before mating, touching their pincers together and moving back and forth in unison. Sometimes they were also rub their tails together or “kiss” with their mouth parts. Pregnancy can sometimes take more than a year in certain scorpion species. Unlike most arachnids, scorpions give birth to live young rather than laying eggs. Babies will ride on their mother’s back for protection.
Scorpions are arachnids, related to spiders. They have eight legs, two claws or pinchers (technically known as “pedipalps”), and segmented tails that end in pointed stingers.
Their body is divided into three parts, including the “cephalothorax”, which contains the main head, the “mesosoma” which is the elongated, segmented body, and the “metasoma” or tail.
Scorpions have two eyes located on top of the cephalothorax, and then between two and five additional pairs of eyes on the front of the cephalothorax. Scorpions use their segmented claws to subdue prey and defend themselves. The tail is composed of five segments, and a final portion with venom glands that ends in a stinger. The stinger is also used for defense, and to kill the scorpion’s prey.
Scorpions have existed for over 430 million years. The overall body plan and look of scorpions has not changed very much in that time. Some scientists believe scorpions originated as sea-dwelling animals before moving onto land, though this has been a subject of debate. Scorpions are arachnids, part of a larger group called Chelicerata that also includes horseshoe crabs, sea spiders, ticks, spiders, and whip scorpions.
While a scorpion’s venom is mainly used to help kill their prey, they will also sting to defend themselves. Their venom can be quite potent and in some cases may contain as many as 45 different toxins. Most species have stings that cause discomfort or pain but aren’t seriously dangerous. However, 25 species of scorpion have dangerous venom that can potentially kill a human. If someone lives in an area known to have scorpions, it is always recommended to check shoes and clothes, fill in cracks that could house scorpions, and avoid walking barefoot.
