Emperor Scorpion Anatomy & Facts

The scorpions body is divided into two main sections. The prosoma and the opisthosoma.

  1. Prosoma: The front of the scorpions main body. The prosoma is the head and thorax of the scorpion
  2. Opisthosoma: The rear of the scorpion main body, or the abdomen of the scorpion

From there, we move on to the other parts of the scorpion.

  • Metasoma: Five segments located after the opisthosoma, or the tail.
  • Telson: The bulb on the end of the metasoma, or tail that holds the stinger
  • Aculeus: The actual stinger. It’s hollow to allow venom to pass trhough it.
  • Chelicerae: The mouthparts of the scorpion
  • Genital opercula: The reproductive area of the scorpion, usually in an oval shape
  • Pectines: The feathery sensory structures found ventrally on teh scorpion.
  • Pedipalps: The “arms” bearing the scorpions pincers.
  • Chelae: The claws, or pinchers.
  • Legs: Used to walk around with…
  • Trichobothrium: The large hairs found on the chelae, used as sensors.

Are Scorpions Venomous?

All scorpions possess venom, but of them only fifty or so species are considered medically significant. Which means, if you get stung, by all but fifty species, you need not worry about running to the hospital. Mild to severe discomfort may be encountered, but unless you have an allergic reaction to their sting, you should be fine. Although many experts suggest that if you’re allergic to bee or wasp stings, you may also want to avoid scorpion stings.


Unlike the majority of the arachnid family, scorpions give live birth. After the babies are born, they stay on their mothers back, usually until their first molt. This stage is called the first instar. The instar, is the period of time between a scorpion’s molt. Starting at birth, the instar continus until their last molt, and they reach maturity. The average being between five and seven molts, for most scorpions to reach maturity. Most scorpions reproduce sexually, however there are a few who reproduce asexually. A few examples being; Hottentotta hottentotta, Hottentotta caboverdensis, Tityus columbianus, and others.

Do Scorpion’s Glow in the Dark?

It is said that scorpions glow in the dark, and this is not quite true. When exposed to certain ultraviolet light, such as from a black light, scorpions will glow. This caused by a protein found on the outermost layer of the scorpions body that fluoresces in UV light. Young, and newly molted scorpions however will not light up.
