The eight-legged scorpion. They're not insects, they're arachnids. In the same family as spiders, ticks, and mites.
— Allen, about Pulmonoscorpius

Pulmonoscorpius (name meaning "Lung Scorpion"), otherwise known as the Giant Scorpion or simply the "Eight-legged Scorpion", is a genus of giant arachnid scorpion that originated during the Late Carboniferous era in what is now Europe. The high oxygen level in the Carboniferous Period allowed this creature (and many others) to grow to very large sizes.

A couple of Pulmonoscorpius were saved and brought to the park in the Series 1 episode Arthropod Swamp. They reside in the Bug Dome.


Era & DiscoveryEdit

Pulmonoscorpius lived during the Carboniferous, over 300 million years ago, sharing the environment with reptiles, amphibians, and other giant insects. Its fossils were discovered at East Kirkton, West Lothian in Scotland in 1994, and it was named by Andrew J. Jeram.  

Physical AttributesEdit

Measuring a little over 2 feet in length, Pulmonscorpius is a giant scorpion much larger than any modern scorpion. They had a protein in the cuticle, in the exoskeleton and it fluoresced and ultra-violet light.

Because Pulmonscorpius was often called "The Eight-Legged Scorpions", this species of scorpion were arachnids as opposed to insects. As such, they belong to the same family as spider, ticks, and mites.

Behavior & TraitsEdit

Luckily, Pulmonscorpius didn't normally sting, let alone attacked, unless they were being provoked. These scorpions had these sense organs under their bodies called pectins, which worked as vibration detectors. They also often spent time under logs.

Pulmonscorpius had tiny hairs on its body, which they used to detect air currents and sensing vibrations. For example, whenever the prey moved, the scorpion moved towards it. Pulmonscorpius also had small claws but a large sting, meaning they killed their prey using venom whereas scorpions with big claws normally crushed their prey. And scorpion venom is toxic. There are toxins in the stinger that can stop your heart beating and your breathing, but it takes several hours to have an effect and turn out to be toxic or fatal to humans.
