Scorpion

Scorpion is a type of Arachnid that belongs to the order Scorpiones. They are known for their elongated bodies and a segmented tail that is often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions are found widely distributed over all continents, except for Antarctica, in a variety of terrestrial habitats except the high latitude tundra.

Anatomy

Scorpions have two types of exoskeletons that are composed of chitin. The body of a scorpion is divided into two parts: the cephalothorax (also called the prosoma) and the abdomen (opisthosoma). The abdomen consists of the mesosoma and the metasoma.

Behavior

Scorpions are predominantly nocturnal. They are opportunistic predators of small arthropods, although the larger kinds have been known to kill small lizards and mice. The large pincers are studded with highly sensitive tactile hairs, and the moment an insect touches these, they use their chelae (pincers) to catch the prey.

Reproduction

Scorpions exhibit a complex courtship ritual to mate. Most scorpions reproduce sexually, and most species have male and female individuals.

Venom

Scorpion venom serves to kill or paralyze prey. The venom of scorpions is used for both prey capture and defense.

Human interaction

Scorpions are generally harmless to humans and are often kept as pets. However, a few species in the family Buthidae can be dangerous to humans.
