Antennae and compound eyes are appendages that insects have and that arachnids lack.Specifically, insects have three (3) pairs of legs and one (1) pair of antennae. In contrast, spiders have four (4) sets of legs and no antennae. They also see through a series of singular, lensed eyes whereas insects have compound eyes.
No, they do not. They have hairlike setae that anchors them to the ground, but no legs. Their skin is light sensitive. No antennae, and no hard surface.
Yes, snails have eyes on the tips of their upper pair of tentacles, which are located on their head. These eyes can detect light and movement.
