World’s Deadliest Scorpion

The world’s deadliest scorpion is a scorpion called fat-tailed man-killer. The fat tailed scorpion is of the genius Androctonus. Stings from this fat tailed scorpion are painful and will kill you unless treated with antivenom for Androctonus envenomations. Envenomation is the process by which venom is injected into your body by a sting of this scorpion. A scorpion produces venom to kill or paralyze a prey so that it can be eat it. A scorpion will also produce venom as a defense mechanism against its predators. The fat tailed scorpion, as its name would suggest, has a distinctly fat tail. The stings from this scorpion have venom that contains powerful and potent neurotoxins that will adversely affect the functioning of your nervous tissue, and if not treated, you are as good as dead.

Scorpions Lives In Deserts

The deserts and dry regions of the countries like Morocco, Lebanon, Turkey, Jordan, Saudi Arabia, Algeria, Tunisia, Libya, Egypt, Togo, Israel, India, Yemen, Bahrain, Pakistan, Oman, United Arab Emirates, Qatar, Kuwait, Iraq, Iran, and Afghanistan are home to the world’s deadliest Scorpion – the fat tailed scorpion.

Fat Tailed Scorpion

The fat tailed scorpion is not all that big as you would imagine. No, the fattail scorpion is only 10 cm long but is fast and aggressive depending on prevailing temperatures. Ideal temperatures range is between 28°-36° C during the day.

The fat tailed scorpion has a lifespan of 5 years. This scorpion does not dig tunnels but will usually make scrapes under stones and rocks. Some species of scorpions like hadogenes scorpions can live up to 25 years.

Scorpions Eat Lots of Meal in One Sitting

Scorpions can stay for six good months without food because they have a low metabolic rate, efficient food storage organ, inactive lifestyle, and limited excretion. But when they get a meal, they can eat a lot of it in one sitting. A scorpion uses its pincers to catch a prey. The prey is then given a dose of the venom to paralyze it before being crushed into a meal. The chelicerae are the claw-like structures from the mouth that are razor sharp and are used for eating the meal. A scorpion has external digestion and only the liquid form of the meal is ingested. Solid indigestible materials are thrown away.

Mating Ritual with a Dance and a Kiss

Mating in scorpions is a process of complex courtship and the mating ritual may take between 2 hours and up to 25 hours. The mating ritual starts with a dance called promenade à deux where the female scorpion is led by the male scorpion in search of a place to deposit male’s spermatophore. A spermatophore is a protein capsule containing a mass of spermatozoa. The courtship ritual will include instances of rapid and forceful shaking and vibration as well as cheliceral kisses. A cheliceral kiss is a kiss in which the male scorpion's claw-like mouthparts grasp the female scorpion's mouthparts in an intimate manner. When the pair has found a suitable place to deposit the spermatophore, the male deposits the spermatophore and guides the female at the deposited spermatophore. The female will pick the spermatophore into her genital opercula. Once inside the female, the spermatohore will release sperms which will fertilize the female’s eggs. The male scorpion will watch very carefully, and as soon as the spermatozoa are inside the female’s body, the male will run away very fast, otherwise he will risk being cannibalized by the female scorpion.

Scorpions are Arachnids

The six common classes of animals are mammals, birds, fishes, reptiles, amphibians and anthropods. A grasshopper and a scorpion are in the class of anthropods. A grasshopper belongs to a sub-class called insects (with six legs). A scorpion belongs to a sub-class called Arachnids (with eight legs). Members of the Arachnids include scorpions, spiders, ticks, mites, and solifugae (like camel spider).

The Death Stalker

Another very poisonous scorpion after the fat tailed scorpion is the death stalker. The death stalker is also known as Palestine yellow scorpion, or Israeli desert scorpion. This scorpion has a length of about 5 cm. The venom from this death stalker can kill a child and the sting is very painful. The venom of death stalker contains peptide chlorotoxin which is an ingredient with high potential for curing human brain tumors and aids in regulating insulin for the treatment of diabetes. While you may be told that in Shandong, China, they fry scorpion as a traditional dish, the superior Chinese medicine does however have analgesic and antidote made from scorpion wine and snake wine.

Keeping Scorpions as Pets

Deadly as they are, scorpions are kept as pets by some people. I would not recommend keeping of scorpions as pets because of the following reasons:

  1. A scorpion can stung you and you will feel a lot of pain and you may die.
  2. If stung by scorpion you will seek medical attention and doctor’s fees are high which may be paid by your next of kin after you are dead.
  3. A scorpion can sting other peoples in your neighborhood so you need insurance for this.

Nice website you have got goin'!

Suggestions on March 25, 2016:

I am very glad to have this website. It has provided me with a lot of information. But, it would be helpful if you added a list of facts. You should also add the life cycle to it. Also, maybe considering adding the other scorpion into a different place because some people like me only need to know about one of the scorpions. People would rather focus on one subject rather than multiple. Please put this in your mind. Thanks!

I never knew that. That is interesting.

Wesman Todd Shaw from Kaufman, Texas on April 04, 2012:

Great article you have here! I discovered this hub while writing my own about scorpions. We have a painful little variety of scorpions living here in Texas. I'd never have guessed that some species could live to be 25 years - that is amazing!

I'm going to put this hub as a link in my own - because it is a very nice one!
