Hey there!
A few similarities between Pseudoscorpions and scorpions include:
1. Both are <span>arachnids
</span>2. Have pedipalps in front of their body
3. Have <span>hard exoskeletons
</span>4. Have pear shaped bodies
Although there are some similarities, there are several differences as well. A common difference is that Pseudoscorpions can't sting their prey while scorpions on the other hand, can.
Thank you!
