Types of scorpions

Within the arthropod invertebrates , there is the class of arachnids that includes the order Scorpiones, commonly known as scorpions or scorpions. Yes, you read that right! Scorpions and spiders share the same class since they are evolutionarily related.

How many species of scorpions are there

Throughout the planet Earth there are around 2,000 species of scorpions grouped in 13 families. All of them are characterized by presenting specialized venom to obtain the greatest effectiveness when it comes to catching their prey, but there is no need to worry, only between 30 and 40 species of those 2,000 are scorpions so poisonous as to be capable of cause death to people, the rest can cause some type of allergy or poisoning.

In the following sections we will show you different types of scorpions and also which are poisonous scorpions and which are not.

One of the types of scorpions from Argentina are those of the genus Tityus , in particular Tityus argentinus . Its appearance is easy to distinguish: dark gray body with yellow or brown limbs. Regarding its venom, it presents neurotoxins that affect the nervous system of its prey, even that of humans. However, it is not an aggressive species, it only bites to defend itself.

Morelos scorpion or scorpion

The Morelos scorpion ( Centruroides limpidus ) is one of the most poisonous types of scorpions in Mexico – and in the world. The Morelos scorpion sting causes severe problems in the respiratory system of people. It can measure up to 12 cm and has a brownish coloration, mainly in its pincers.

One of the most typical types of scorpions in Spain is the common yellow scorpion ( Buthus occinatus ), which is also distributed throughout Italy and France. Its name precisely refers to its appearance since it has a yellowish coloration although darker on the body. Regarding its poison, although it is of medium danger, it can be lethal for children and the elderly.

This black-tailed scorpion ( Androctonus bicolor ) not only has a black tail, but its entire body is dark in color and robust in appearance. Its distribution includes Africa and the Middle East and its powerful poison affects the nervous system and can be lethal.

Emperor scorpion

The emperor scorpion ( Pandinus imperator ) is one of the largest scorpion species in the world . Its body is robust, dark in color and measures approximately 20 cm. Regarding its distribution, it is endemic to West Africa. Often, this species is commercialized in the pet market because its venom is mildly harmful, it does not cause major complications unless the person is allergic.

Thick-tailed spitting scorpion

The peculiar name of the thick-tailed spitting scorpion refers to the fact that this species is capable of launching its venom at long distances, causing temporary blindness and eye damage. This scorpion ( Parabuthus transvaalicus ) is found to the south-east of the African continent and can measure more than 15 cm.
