I did measure every single spider. All 200 something of them. If this becomes my thesis work, I will be measuring A LOT more of them.
I did a series of measurements:
(From my poster)
Figure 2. spider anatomy showing each measurement taken:
body length (a), abdomen length (b), abdomen width (c),
cephalothorax width (d), and one of each pair of legs (e-h).
I then took each of those measurements and divided them by the body length. That gave me a series of indices- these indices basically told me which body part was most important in determining foraging behavior- as well as which guild will be the most easily recognizable from their morphology.
So, in short, to really answer your question- I was most concerned with a spider’s “shape”. Because once I divided by body length, that is what the index would tell me.. Cephalothorax shape, abdomen shape and so on… except for legs- legs was more about the length.
