Difference Between Alacrán and Scorpion

Have you ever wondered what the difference is between an “alacrán” and a scorpion? The truth is—there is no difference. They are the same animal. The only distinction comes from language and regional usage: in some countries people call them alacrán, in others they say scorpión. Still, many believe these names refer to two different species or that one is more venomous than the other, which is a common misconception.

In this article, we’ll explain the origin of both names, the biology of scorpions, the effects of their sting, and what to do in case of an encounter.

Alacrán and Scorpion Are the Same Animal

scorpions.html">Scorpions belong to the order Scorpiones, within the class of arachnids (like spiders and ticks). Their most recognizable features are:

• Pedipalps: two claw-like appendages used to grasp prey.

• Segmented tail: ending in a venomous stinger.

There are about 1,500 species of scorpions worldwide, ranging in size from less than 1 cm to as long as 21 cm.

Habitat: Most scorpions prefer rocky or sandy environments, especially deserts and tropical regions. Some species live in caves or even climb trees. They generally avoid light and human presence, although some species benefit from human settlements because of the warmth and availability of insects.

Diet: Mainly insects, but also spiders, lizards, and occasionally even small mammals such as mice. Scorpions can survive for months without food, but water is essential.

Venom: Although scorpions have a deadly reputation, only a small fraction of the 1,500 known species are dangerous to humans. Roughly speaking, lighter-colored scorpions (yellow, beige, white) tend to be more venomous, while darker ones (brown, black) are usually less so.

Regional Use of the Names

• Alacrán

• More commonly used in southern Mexico.

• In northern Mexico, the term sometimes refers only to venomous species.

• In Spain, “alacrán” is considered somewhat old-fashioned and is less used. In rural areas, it may refer to small scorpions, and in some regions it even refers to a type of cricket.

• Scorpion (Escorpión)

• More common in northern Mexico, influenced by the English word scorpion.

• In these regions, some people say “alacrán” for venomous species and “escorpión” for less dangerous ones.

• In Spain, “escorpión” is the most widely used term, though sometimes reserved for larger species, with “alacrán” for the smaller ones.

Characteristics of a Scorpion Sting

The seriousness of a scorpion sting depends on several factors:

1. Species – Only a minority are truly dangerous to humans.

2. Size – Larger scorpions can store more venom; adult females often have stronger venom.

3. Venom amount – Usually only a small dose is injected, but multiple stings increase risk.

4. Location of sting – Direct skin contact delivers more venom than through clothing.

5. Victim’s age and health – Children and the elderly are more vulnerable.

6. Individual sensitivity – Some people react more strongly due to allergies or weaker immune response.

Symptoms of a Scorpion Sting

Mild cases may involve only local irritation, while dangerous species can cause serious systemic reactions. Possible symptoms include:

• Pain and burning at the sting site

• Swelling and discoloration

• Numbness and drowsiness

• Elevated blood pressure, sweating, and salivation

• Muscle contractions in fingers and toes

• Tingling in face and throat, difficulty swallowing or speaking

• Abdominal spasms, vomiting, hallucinations

• Partial or total paralysis

• High fever (up to 40°C / 104°F)

• Internal bleeding and heart complications

• Rapid, shallow breathing

If untreated, severe cases may result in respiratory failure and death, especially in children or elderly victims.

What to Do After a Scorpion Sting

1. First Aid

• Apply a tourniquet above the sting site to slow venom spread, loosening it every 20 minutes to maintain circulation.

• If possible, use a sterile blade or suction device to help remove venom (⚠️ never use your mouth to suck out venom).

2. Medical Care

• Seek medical attention immediately.

• Doctors may administer antivenom serum if appropriate and monitor vital signs.

3. Time Window

• A sting from a highly venomous scorpion can kill within 24 hours without treatment.

• In hypersensitive individuals, death may occur in as little as one hour.

Conclusion

• Alacrán and scorpion are the same creature, just different names.

• Only a few of the world’s 1,500 species are truly dangerous to humans.

• Most stings cause only local discomfort, but highly venomous species can be fatal without prompt treatment.

• Scorpions have existed for over 400 million years and play a crucial ecological role in controlling insect populations.

Understanding their biology and the myths around their venom helps us respect these fascinating arachnids while also knowing how to stay safe.
