The Sandworm developed pressure sensing organs allowing them to sense vibrations traveling trough the sand. They began hunting surface creatures by tracking their vibrations. They grew quite large.

They developed specialized muscles right underneath their armor plates. These muscles constantly undergo micro contractions. This causes the armor plates and the sand around them to vibrate. The Sandworm swiftly burrows through the sand. The pressure sensitive organs filter out vibration from these muscles.

This caused the worm to become vulnerable to vibrations near its own frequency. They suffer from senory overload from other worms. Worms avoid each other except during reproduction. 

To circumvent this overload, the worms have developed a reproductive tactic. The males lay a slowly pulsating "egg" that contains their sperm. These eggs pulsate with a certain frequency, drawing the females near them. When they find these eggs, they devour them and inseminate themshelves The female lays proper eggs afterward.
