Inclusion whit more than six legs - model 2

 
The different steps may contain scientific terms which may seem encouraged - I will recommend to search the word on google. Meanwhile, I am looking for pictures to illustrate each step - It is also the intention that these images will illustrate the foreign words. Can you help or do you maybe have access to such images, then I would be very happy to hear from you. Contact me here
  1. - Four pairs of legs - go to 2
    - More than four pairs of legs - go to 6

  2. - Abdomen with distinct segments - go to 3
    - Abdomen without distinct segments - go to 5

  3. - Conspicuous "pincers" (pedipalps) in front of shorter legs - go to 4
    - Without "pincers," long and slender legs =Opiliones (Daddy-Longlegs)

  4. - Fairly large, the abdomen ends in a stinger =Scorpiones (Scorpions)
    - Small, the abdomen does not end in a stinger = Pseudoscorpiones (Pseudoscorpions)

  5. - Body clearly divided into two main parts (cephalothorax and abdomen) =Araneae (Spiders)
    - Oval-shaped body not divided into two main parts
    =Acari (Mites & Ticks)

  6. - Seven pairs of tiny legs, some roll up into balls
    =Isopoda (Pillbugs, sowbugs)
    - More than seven pairs of legs, they don't roll up into balls - go to 7

  7. - Tiny bodies, 10 - 12 pairs of legs =Symphyla (Pseudocentipedes)
    - Bodies often fairly large, with >15 pairs of legs - go to 8

  8. - Flattened bodies, with one pair of legs attached to each body segment =Chilopoda (Centipedes)
    - Bodies usually tubelike, with two pairs of legs attached to each body segment =Diplopoda (Millipedes)
