I had one of those in a tree in the cemetery at the end of my road about 5 years ago. Do you think they might eat dead people? They are definitely carnivorous. Observe its feeding behavior.
Only two eyes-birth defect?
Two eyes good ,eight eyes is just so early days of evilution ,haha .I don’t trust anything with more eyes that me .
Talking of eyes ,what is it in the compound eyes of Dragonflies and Mantises that make they look as if they have pupils ?

Never mind found out it is called a pseudopupil .
There’s only two globes visible, but they’re just hiding all the single-neuron eyes in the back. It’s quite a rudimentary system but it works well enough for a spider that has to bash its head into a tree to catch food rather than calmly waiting for food to come to it.
Perhaps they have evolved to look like feathers to thwart predators that go for the eyes first, such as crows.
