Scorpiones

Scorpiones

Scorpiones (pronounced: skor-pee-oh-nees) is an order of arachnids, commonly known as scorpions. They are characterized by their eight legs, a pair of grasping pedipalps, and a narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger.

Etymology

The term "Scorpiones" is derived from the Latin word "scorpio", which is itself derived from the Greek word "skorpios". Both words mean "scorpion".

Characteristics

Scorpions are known for their elongated bodies and their venomous stingers. They have a complex life cycle and exhibit a range of characteristics that are not commonly found in other insects and arachnids. These include a long gestation period, live birth, and the maternal care of the young.

Classification

Scorpions belong to the class Arachnida, which also includes spiders, mites, and ticks. They are further classified into the order Scorpiones. There are over 2,000 known species of scorpions, grouped into 13 families.

Habitat and Distribution

Scorpions are found on all major land masses except Antarctica. They inhabit a wide range of habitats, including deserts, grasslands, forests, and caves.

Medical Significance

While all scorpions possess venom that they use for hunting and self defense, only about 25 species have venom that is dangerous to humans. The most dangerous scorpions belong to the family Buthidae, which includes the notorious deathstalker and the Indian red scorpion.
